SOFTWARE INSTRUCTIONS ARE FOUND EITHER ON SCREEN OR IN A .DOC FILE ON DISK. Even if you're in a hurry to start using your new modem, please take a few minutes to read the following instructions carefully. They've been written to guarantee that you get the most from your equipment and that it provides you with years of excellent service. Congratulations on making a smart buy. With your new Aprotek Minimodem-C, communications software and your computer you can use the telephone system to enter the exciting world of data communications. With the enclosed software, you'll have immediate access to the latest business reports and stock market quotations. You can do your banking, read recent news stories, receive weather and sports information, make airline reservations, play games, and go shopping. You'll have access to hundreds of databases on every subject: movie reviews, library files, business records, consumer reports, encyclopedias, software reviews and more. You'll be able to exchange messages or programs with other computers or make contact with computer users everywhere. Any information you receive can be saved on diskette. If you have a printer, you can also make a printed copy. A FEW RULES: The Federal Communications Commission (FCC) has established rules governing how modems may be connected to the telephone system. Before connecting your modem you must tell your local telephone company that you intend to connect an FCC registered modem to your telephone line. They'll ask you the following information: 1. Your telephone number. 2. Your modems' FCC Registration Number and Ringer Equivalence (both are located on the underside of the modem.) 3. The USOC telephone jack needed for the connection: RJ11. (If your home is equipped with the older 4 prong telephone jacks, you must buy a RJ11-to-4 prong adapter from your local computer dealer, electronics dealer, telephone store, or hardware store.) FCC rules also require you to notify your local telephone company before permanently disconnecting your modem. The telephone company may make changes in its service and operations from time to time. If these changes will affect the operation of your modem, they'll notify you before doing so. THE RIGHT CONNECTIONS First make sure you have the right equipment; specifically a Commodore 64 or 128 with television or video monitor (color or b&w); a Commodore 1541 or 1571 Disk Drive (for loading the software); the Aprotek Minimodem-C with supplied seven foot attached telephone cord; the communications software diskette. [end page 2] [start page 3] Connect Minimodem-C to your phone line and Commodore: 1. Make sure your computer is OFF before connecting the modem. 2. Insert the modem into the User Port of your C64 or C128. Be sure to insert it completely into the computers connector, and be sure that the LEDs and top label are facing up. 3. Connect the modem to the telephone line by plugging the other end into the phone wall outlet. If you wish to use a phone on the same outlet, you may wish to acquire a "Y" adapter, available through Aprotek or a local phone or electronics store. NOTE: If you have problems with the telephone line after connecting the modem to the phone line, disconnect the modem. If it's responsible for the problem, don't use it until the problem is fixed. The telephone company is not responsible for a disturbance caused by non-telephone equipment. They may charge you for a service call if the problem is not in their equipment. Now load up your communications software, and set the modem selection and parameters as required. If you are not sure of what to set for the parameters, start with 8 bit word length, no parity, and one stop bit. We can now try "talking" to Minimodem-C. First, go to the 'terminal' mode of the terminal program. Type in "AT", then hit return... Minimodem-C should reply "OK". This will show that you are communicating with the Minimodem. Simply load the terminal software and follow the on-screen instructions. For basic modem usage you do not need to read any further. The rest of this manual is directed towards the advanced user. It is NOT necessary to understand the rest of this manual in order to use Minimodem-C. The following information is given to help the advanced user gain complete control over the full range of power that Minimodem-C has. Terminal mode vs. Command mode Minimodem-C has two different operating modes. Command mode is the mode that the modem is in when you are not connected to any on-line service. If you are connected to an on-line service, the modem is in 'terminal mode'. There are two ways of changing from terminal mode to the command mode. If Minimodem-C detects a loss of signal, it will go to command mode automatically. Or you can use the 'escape code' to escape to the command mode. This is one second of silence, followed by '+++', and another second of silence. This unusual sequence will never be found during on-line communications. The command mode is used for modem initialization, dialing, and changing various registers, among other things. All commands (with the exception of '+++', and 'A/'), start with the letters AT, which signals 'ATtention'. The letters 'AT' may then be followed by a string of up to 40 characters in length. Example - ATL3DT5551212 will set the speaker to high volume, then tone dial the number '555-1212'. While in the terminal mode, Minimodem-C will be in one of two sub-modes; Originate or Answer. When modems communicate with each other, one modem will be in originate mode, and the other will be in the answer mode. When calling an on-line service, Minimodem-C will automatically default to the originate mode. There is however, a dialing command to force Minimodem-C to place a call in the answer mode. This will be needed in very rare cases to call an originate mode only modem. (See 'Dialing Commands') [end page 3] [start page 4] MODEM COMMAND DESCRIPTIONS AT - ATtention command. All modem commands with the exception of 'A/' and '+++', must begin with this command. A/ - Repeat previous command. Do not follow this with . +++ - Escape code sequence. One second of silence, followed by three plus signs, followed by one second of silence. Do not follow this with . (Escape code set by S2, silence guard time set by S12) DIALING COMMANDS D - Dial a number. This command is normally followed by either a 'P' or a 'T' command. P - Pulse dial. T - Tone dial. , - Pause for two seconds. (Pause time set by S8) ! - Signal a 'Flash' tone. / - Wait for 1/8 second. @ - Wait until silence is detected. W - Wait for a second dial tone. This is useful in dialing long distance through a long distance service. ; - Return to Command mode after dialing. R - Reverse mode. This is used to call an originate only modem. OTHER COMMANDS A - Answer a call without waiting for a ring. This command is normally used to switch from a voice call to data. B0 - CCITT V.22 mode. B1 - Bell 103 and 212 modes. (Default) CCITT V.22 is the European phone system standard. Bell 103 and 212 are the American phone system standard. C0 - Transmit carrier off. C1 - Carrier on. (Default) Specialized commands not normally needed by most users. E0 - Command characters not echoed. E1 - Command characters echoed. (Default) Control whether the modem echoes back to your screen the command characters you type. This command is used by many software programs. F0 - Half duplex. F1 - Full duplex. (Default) Half duplex is normally only needed if you are communicating from your terminal to another computers terminal program. Half duplex echoes what you type directly to your screen. If you are getting either no characters or double characters, switch duplex. H0 - On hook. (Hang up) H1 - Off hook. (Pick up the phone line) The ATH command is commonly used after a +++ escape to terminate a call. The ATH1 command is a special command not normally used. I0 - Minimodem product code. I1 - ROM checksum. I2 - Internal memory test. These commands are used during factory testing only. [end page 4] [start page 5] L1 - Low speaker volume. L2 - Medium speaker volume. (Default) L3 - High speaker volume. These commands may be used to change Minimodem-C's speaker volume to personal preferences. M0 - Speaker always off. M1 - Speaker on until carrier detect. (Default) M2 - Speaker always on. Used to change the speaker operation to personal preferences. Many software programs use ATM0 to turn off the speaker. O - Go to on-line state. O1 - Remote digital loopback off. (Default) O2 - Remote digital loopback request. Specialized commands not normally needed by most users. Q0 - Result codes displayed. (Default) Q1 - Result codes not displayed. Minimodem-C will normally reply with the results of any command issued to it. These commands are normally used by software programs. Sr? - Request current value of register r. Sr=n - Set register r to value n. These two commands will allow the reading or setting of S register values. The complete description of the 'S' registers is in the next section. V0 - Digital result codes. V1 - Word result codes. (Default) Minimodem-C can give the results of a command in either digital or word format. Many programs find it easier to work with digital result codes, rather than words. The complete list of result codes is in the Appendix A. X0 - Basic result codes. (Default) X1 - Extended result codes. Result code 'CONNECT 1200' enabled. X2 - Enables dial tone detection. X3 - Enables busy tone detection. X4 - Enables both dial tone, and busy tone detection. The default basic result codes are OK, CONNECT, RING, NO CARRIER and ERROR. For software programs that can handle the extended result code, ATX1 will allow CONNECT 1200. The ATX4 command can be very useful if you are dialing from the terminal using the AT commands. This enables both the dial tone and busy tone detect, and will make it easier to determine if the number is busy. Y0 - Long space disconnect disabled. (Default) Y1 - Long space disconnect enabled. Specialized commands not normally needed by most users. Z - Software reset. This restores all default values. The dip switches are also read. If you change any dip switch settings while the modem is powered on, you must reset the modem with ATZ. S REGISTERS These registers are internal to Minimodem-C, and can be read from or written to in order to change the way it operates. Any changes will be retained as long as the modem is powered up, but will be lost when you turn the power off. The format for reading the registers is ATSr?, where r is the register number that you wish to examine. The format for changing a register's contents is ATSr=n, where r is the register number you wish to change, and n is the number you wish to change it to. For example; ATS0=3 will set Minimodem-C to auto-answer on the third ring. ATS0=0 will not answer at all. Defaults are listed after the description. [end page 5] [start page 6] S0 Auto Answer ring number. This register controls the number of times the modem will allow the phone to ring before answering. The value can range from 0-255. (S0=0) S1 Ring Counter. Counts the number of times that the phone rings before answering. Automatically resets itself. This is a read only register. (S1=0) S2 Escape code character. This register holds the value of the ASCII character used as an escape code. The value can range from 0-127. (S2=43) S3 Carriage return character. This register holds the value of the ASCII character used to indicate a carriage return. The value can range from 0-127. (S3=13) S4 Line feed character. This register holds the value of the ASCII character used to indicate a line feed. The value can range from 0-127. (S4=10) S5 Backspace character. This register holds the value of the ASCII character used as a backspace. The value can range from 0-32, or 127. (S5=8) S6 Wait time for Dial tone. This register controls how long the modem will wait for dial tone after seizing the line. Measured in seconds, the value can range from 2-255. (S6=2) S7 Wait time for Carrier. This register controls how many seconds the modem will wait for carrier before reporting 'NO CARRIER'. The value can range from 1-255 seconds. (S7=30) S8 Pause time. This register controls how many seconds the modem will pause when encountering a comma (,) during a dialing sequence. The value can range from 0-255. (S8=2) S9 Carrier detect response time. This register controls the length of time in tenths of a second that a carrier must be detected before being accepted as a valid carrier. The value can range from 1-255. (S9=6) S10 Delay between carrier loss and disconnect. This register controls how long, in tenths of a second, before the modem will disconnect after a loss of carrier is detected. The value can range from 1-255. (S10=7) S11 Touch Tone duration time. This register determines, in milliseconds, the duration of the tone dialing signal. The value can range from 50-255. If you get no connections because the modem is dialing too fast, you can slow the dialing by changing this register. (S11=70) S12 Escape code guard time. This register determines, in 1/50 second intervals, the delay time before and after the '+++' escape code. The value can range from 20-255. (S12=50) S13 UART status register. This is a read only register which contains the status of Minimodem-C's UART (Universal Asynchronous Receiver/Transmitter). The individual bit- mapped definitions are as follows: UART status register bits 0-7 bit 0 - undefined bit 1 - undefined bit 2 - 0 parity disabled 1 parity enabled bit 3 - 0 odd parity 1 even parity bit 4 - 0 seven data bits 1 eight data bits bit 5 - undefined bit 6 - 1 buffer overflow flag (causes ERROR result code to be sent) bit 7 - 0 8th data bit set to space (if bit 4 = 1) 1 8th data bit set to mark (if bit 4 = 0) [end page 6] [start page 7] S14 This is a read only register which contains the status of different options. The individual bit-mapped definitions are as follows: Option register bit 0-7 bit 0 - 0 switch 5 off 1 switch 5 on - holds state of switch 5 (auto-answer) at power on or reset time. bit 1 - 0 local echo disabled 1 local echo enabled bit 2 - 0 result codes enabled 1 result code disabled (quite command) bit 3 - 0 digit result codes displayed 1 word result codes displayed bit 4 - 0 enable command recognition 1 disable command recognition bit 5 - 0 UK 33/67% make/break ratio 1 US 40/60% make/break ratio bit 6 - 0 CCITT V.22 1 Bell 103/212A mode bit 7 - 0 Long space disconnect disabled 1 Long space disconnect enabled S15 Flag register. This is a read only register which contains the transmission mode, duplex, baud rate, and connection status. The individual bit-mapped definitions are as follows: Flag register bit 0-7 bit 0 - same as setting of bit 4 bit 1 - same as setting of bit 5 bit 2 - 0 answer 1 originate bit 3 - 0 half duplex 1 full duplex bit 4 bit 5 baud rate ----- ----- --------- 0 0 undefined 1 0 110 0 1 300 1 1 1200 bit 6 - 0 no connection 1 connection established bit 7 - undefined S16 Self Test register. This register allows you to conduct analog, digital and DTMF testing on Minimodem-C. The values allowed are 0-2,4. These functions, as well as other test functions, are described as follows: [end page 7] [start page 8] TESTING MINIMODEM-C Product Code, Check Sum, Internal Memory - I0, I1, I2 To display Minimodem-C product code, TYPE: ATI0 (I zero) The two left digits represent the product. The right digit is the product's revision number. To display the modem's ROM check sum, TYPE: ATI1 This value is used for testing the modem when it is manufactured. To test the modem's internal memory, TYPE: ATI2 If the internal memory is functioning, OK is displayed. If it is not, ERROR is displayed. Testing Answer and Originate Functions Off-Line Analog Loopback You don't have to be connected to the telephone system to test Minimodem-C answer and originate functions. First, disconnect the modular telephone plug from the wall jack. To test specific answer mode functions, TYPE: ATS16=1A To test specific originate functions, TYPE: ATS16=1D In both cases, a CONNECT result code is displayed. At this point, start typing on your keyboard. If the correct characters are displayed on your screen, your Minimodem-C is working correctly. To end the test, TYPE: +++ When OK is displayed, TYPE: ATH Note that S16 is automatically set to zero. Do an On-Line Analog Loopback if you are on line with another user, and getting a lot of errors, TYPE: +++ to return to command state. Then, TYPE: ATS16=1O Remember that the O command puts the modem back on-line. Start typing on your keyboard. Everything you type should be transmitted to the other modem and displayed on your screen as well. If the information is correctly displayed on your screen, then both your transmitter and receiver are working properly. The problem is either in the phone line or with the other modem. To end the on-line test, TYPE: +++ When OK is displayed, TYPE: ATS16=0 and press the return key to put Minimodem-C back on-line in normal mode. [end page 8] [start page 9] Testing the DTMF Dialer TYPE: ATS16=2 Ordinarily, the spacing between touch-tones is determined by the value set in register S11. But when you enter this command, the value set in register S11 does not apply. The tone is transmitted until you press another key. This allows time for measuring the amplitude of the signal. This command is used only at the factory. Digital Loopback Command The purpose for digital loopback is to allow the other user to determine whether his modem is working properly. To begin the test, TYPE: +++ to return to command state. Then, TYPE: ATS16=40 Note that you must be on line for this command to work. The other user begins typing, looping his data back to his screen through your Minimodem-C. You will not see what he is typing. APPENDIX A RESULT CODES DIGITAL CODES WORD CODES DESCRIPTIONS ------------- ---------- ------------ 0 OK Command executed without error. 1 CONNECT Connected at 300 or 1200. Connected at 300 if X1, X2, X3, or X4 commands are in effect. 2 RING Ring signal detected (see note). 3 NO CARRIER Carrier signal not detected or lost. 4 ERROR Illegal command. Error in command line. Command line exceeds 40 character buffer. Invalid character format at 1200 baud. 5 CONNECT 1200 Connected at 1200 baud. Results from X1, X2, X3 or X4 commands only. 6 NO DIALTONE Dialtone not detected and subsequent commands not processed. Results from X2 or X4 commands. 7 BUSY Busy signal detected and subsequent commands not processed. Results from X3 or X4 commands. 8 NO ANSWER Silence not detected and subsequent commands not processed. Results from @ command only. NOTE: When Minimodem-C detects a ringing on the telephone line, it sends a RING result code. However, it will answer the call only if it is in auto-answer mode or is given an A command. [end page 9] [start page 10] Appendix B MINIMODEM-C COMMODORE SIGNAL INTERFACE The following shows the signal interface between the Aprotek Minimodem-C double-sided 12-pin-card-edge connector and the computer's User Port. Pin Signal Description --- ------ ----------- 1 Gnd Circuit ground 2 +5V +5 volts DC from the computer 12 Gnd Circuit ground A Gnd Circuit ground B RXD Receive Data from the modem C RXD Receive Data from the modem E DTR Data Terminal Ready F RI Ring Indicator from the modem H CD Carrier Detect from the modem J HS High sped detect from modem M TXD Transmit data from the computer N Gnd Circuit ground Appendix C DIP SWITCH SETTINGS There is an 8 position switch on Minimodem-C. Access to the switches is through the top cover. Be sure the power is OFF in Minimodem-C and it is unplugged from your computer. Open the cover by pressing on the side of the plastic case opposite the LEDs. The switches are near the computer connector. Use a small pointed object (but not a pen or pencil), to change the switch settings only when you are certain of the function of a particular switch. Be certain that only those switches you intend to change are switched, not the adjacent ones as well. Functions and defaults are: SW1 Switch 1 & 2 are used together. Only one of the two can be turned on at one time. SW1 ON puts Minimodem-C into the Hayes emulation mode. SW2 must be OFF when SW1 is ON. Conversely, SW2 ON Puts Minimodem-C into the 1670 mode and SW1 must be OFF. SW3 (Default OFF) Causes result codes to be sent to the computer as words. When ON digital codes are sent (see result codes in Appendix A). This setting can also be changed by entering the "V" command (see "Other Commands") SW4 (Default ON) Causes result codes to be sent. Otherwise (when OFF) commands sent from the computer are performed but the result of the commands are not sent back to the computer. SW5 (Default OFF) All characters received from the computer are echoed (to the screen). When ON the characters are not echoed unless Minimodem-C is set for half duplex and on line. This can also be changed by the "E" command. (See "OTHER COMMANDS") SW6 (Default ON) Auto answer disabled when ON. When this switch is turned OFF, Minimodem-C will answer an incoming call on the first ring. This function can be changed by writing to the S0 register. Any number of rings (to 255) can be selected. SW7 (Default ON) When ON Minimodem-C is in the "DTR" or Data Terminal Ready mode. Some Commodore software does not set the DTR signal line on the interface and this switch allows you to force it on. SW8 (Default OFF) When OFF Minimodem-C has a rotary dialing ratio of 40-60 make-break and supports Bell 103 and 212A modes. When ON the European standard of 33-67 is used and supports CCITT V.22 and V.21 modes. (This does not signify that Minimodem-C is approved for use on European phone systems.) This function can also be changed with the "B" command. [end page 10] [start page 11] FCC Notice The Federal Communication Commission has established technical standards regarding radiation of radio frequency energy emitted by computing devices. The Aprotek Minimodem falls under the rules for class B computing devices and the following information must be supplied in accordance with 47 CFR 15.838: This equipment generates and uses radio frequency energy, and if not installed and used in strict accordance with the installation and operating instructions contained in this manual, may cause interference with radio and television reception. The Aprotek Minimodem has been type-tested and found to comply with the limits for a class B computing device in accordance with the specifications of subpart J of part 15 FCC Rules, which are designed to provide reasonable protection against radio and television interference in a residential installation. However, there is no guarantee that interference will not occur in your particular installation. If this modem does cause interference with radio or television reception, which you can check by simply turning the modem on and off, you are encouraged to try one or more of these corrective measures: -- Reorient the receiving antenna. -- Move the modem away from the receiver. -- Plug your computer system into a different outlet, so that the receiver is on a different branch circuit. If necessary, consult the dealer who sold you this modem or an experienced radio/television technician for additional suggestions. You might also find a booklet prepared by the FCC helpful. Entitled "How To Identify and Resolve Radio and TV Interference Problems", it's available from: U.S. Government Printing Office Washington D.C. 20402 (Stock number 004-000-00345-4) FCC Regulations FCC regulations prohibit using your modem in the following ways: 1. The modem must not be connected to a telephone which is part of a party line. (a telephone line shared by two or more subscribers). 2. The modem must not be connected to a coin-operated telephone. 3. The modem must not replace your telephone. There must be at least one telephone connected to your telephone line. If you have only one telephone wall outlet, you can satisfy this requirement by installing a "Y" adapter, then connecting both Minimodem-C and telephone.

To view the instructions for CCGMS, hit F4, then 'L' to load the instruction file into the buffer. When CCGMS asks for the name of the file, type "instructions". To view the instructions, you may now hit F4 again. Type "V" to view on screen or "P" for printer. There is a message from the author of CCGMS that may be viewed by hitting F7, then 'V'. Multiterm also has a doc file which can be read or displayed. (mt.doc) On this disk are also several other terminal programs for your use. Multiterm 128 is no longer included, due to our successful search for terminal programs that are more powerful and easier to use. All programs on this disk are menu driven and self-explanatory, thus usually need no instruction manual. While the terminal programs included with your Minimodem-C are all excellent programs; you are not limited to using only these programs. All correctly written terminal programs will work with Minimodem-Cs. If you are experiencing difficulty getting one of these programs to work with a Minimodem-C, contact your dealer, local Commodore User's Group, or call us at (503) 582-2120 (weekdays 8-5), ask for customer service. See reverse side for Beginners Instructions COMMON QUESTIONS AND ANSWERS FOR APROTEK MINIMODEMS: Q: I can't Up/Download from a Bulletin Board... A: This is not a problem of the modem, there are two main types of protocols, Punter and Xmodem. Cannot be interchanged. Q: I can't get the AT10, AT11, AT12, tests to work... A: Look closely, should be ATI0, ATI1, ATI2. Q: I can get the answer mode test to work (pg 8), ie. AST16=1A, but I can't get the originate mode test to work, ATS16=1D. A: You are still in the answer mode test, you must send the escape code sequence, one second of silence +++ then one second of silence. Q: I can't get QLink to work with Minimodem. A: Be sure to set the QLink disk to a 1670 modem. Do this by loading up the change access program, and switching to the 1670 modem type. (LOAD"CHANGE ACCESS",8,1) Minimodem-C should be set to the default switch settings. Minimodem-C24 on 1670 mode. If using a Com-modem adapter, 1670/Hayes switch to 1670. If using USR-232 set switches to modem A, modem B, and Normal. Q: When I type "AT", I get "syntax error". A: You must have a terminal program loaded up, and be in the terminal mode to talk with Minimodem. CCGMS - Load and run, you are now in terminal mode. Multiterm - Load and run. Hit 'T' for terminal mode. Q: What lights are supposed to be lit when first connected to the phone system? A: 1200 Baud (if at 1200 baud), Off-Hook, and Ready Lights. Q: Can I leave my Minimodem plugged in all the time? Does it interfere with any other software? A: Minimodem was designed to be plugged in at all times, and does not interfere with the running of other programs. (Ignore the Minimodem lights when running other programs) Q: Can I use Minimodem to dial a number only? (Such as an automatic dialer). A: Yes, put a semicolon ";" at the end of the number to be dialed, this instructs the Minimodem to return to command mode, and not look for a carrier. Q: While online occasionally odd characters show up on the screen. What's wrong? A: This is a result of static on your telephone line. It will not affect Up/Downloads. If garbage is extensive, have it fixed or dial up another connection. [end front side of read me first sheet] [start reverse side of read me first sheet] BEGINNERS INSTRUCTIONS The following is a step by step procedure to allow you to log on to a Bulletin Board or On-Line Service using CCGMS. 1. With the computer off, plug your new modem into the User Port of your Commodore computer. The User Port is the port on the left back side of the computer. Be sure that the LED lights and top label are facing up. Make sure that you plug it in all the way in and be sure not to disturb or move it during operation. 2. Plug the modem telephone cord into a wall phone outlet. If you wish to use a phone on the same outlet, you may wish to acquire a "Y" adapter, available through Aprotek or a local phone or electronics store. 3. If you are using a Commodore 128, you should switch to C-64 mode before loading this program. Load the terminal program by typing load"ccgms*",8,1 and then depress the return key. As soon as the program is finished loading, type run, and hit return again. 4. The first screen is the terminal mode screen. The command menu for this program can be found by depressing the F4 key.
