1 GENERAL DESCRIPTION Telelink™ I is a program cartridge that enables the user to communicate with another computer over standard telephone lines when used with the AT ARI ® 830™ Acoustic Modem. The AT ARI 830 Modem is fully compatible with the Bell 103A Modem and other similarly operated modems. To use the Telelink I cartridge, connect the ATARI 850™ Interface Module and the ATARI 830 Modem to either the AT ARI 400™ or AT ARI 800™ Personal Computer System.
2 CONNECTING THE SYSTEM Refer to Figure 1 if you have the ATARI820™ or ATARI822™Printer, or Figure 2 if you have the ATARI 825™ Printer, and follow these steps below. For complete instructions to set up your ATARI Personal Computer System, please refer to the ATARI 400 or ATARI 800 Operator's Manual and the appropriate operator's manuals for any additional peripheral equipment you may have.
ATARI 815 DUAL DISK DRIVE OR 810 DISK DRIVE ATARI 400 OR ATARI 800 ATARI 850 INTERFACE MODULE CASSETTE Figure 2 ATARI 825 PRINTER Using the ATARI 825 Printer 1. Plug the ATARI 400 or ATARI 800 computer into the ATARI 850 Interface Module at either peripheral port. 2. Plug the printer into ONE of the following: 3. • The AT ARI 850 Interface Module if using the ATARI 825 Printer (see System Diagram). Use printer cable (AT ARI Part No. CA015544) packaged with the printer.
3 OPERATION You can use the Telelink I cartridge with either the AT AR I 400 or the AT AR I 800 Personal Computer System . Insert the cartridge (see diagram below) in the cartridge slot (LEFT cartridge slot on the ATARI 800). The ATARI 400 and ATARI 800 Personal Computer Systems automatically shut off whenever the cartridge door is lifted . This prevents damage to the computer and to the cartridge.
6 Operation 6. Dial the telephone number to the remote system . 7. When you hear the high-pitched tone, place the telephone receiver into the modem cradle. (See Figure 1 or Figure 2 for positioning the handset onto the modem .) B. When you see the modem READY indicator on, you can begin data transmission . 9. Type in the appropriate " logon" code. This code varies with each particular time-share system.
4 ERROR MESSAGES RS232 Error: 138. This means the ATARI 850 Interface Module did not start up properly. Check to see if your disk drives are OFF and the Interface Module is ON before you turn on your ATARI 400 or ATARI 800 Personal Computer System . Printer Error: 138. There is no printer connected to the system, or its power is turned OFF . Printer Error: 139. The printer is switched OFFLINE (AT ARI 825 Printer only).

5 USER CONTROLS The memory buffer of Telelink I can save up to 1.5K bytes of data received over the modem before the information must be emptied to the printer. Generally speaking, when the buffer is nearing capacity (at 1 K bytes), communications over the modem must be suspended and the contents of the buffer sent to the printer. If the printer is not on, a printer error appears. Exactly how suspension of communication for printing occurs depends on whether you are in the Automatic or Manual Mode.
3. When the printer stops, send the restart ( &ml Ql command (as required by the remote system) to reinitiate communication transmission. The following are the various user controls for Telelink 1: PRINTER CONTROLS FUNCTION KEYS used BEFORE you press l!l.ml to take you back and forth between the Automatic Mode and Manual Mode. If you are in Manual Mode and you want to select Automatic Mode, do a Em1.1 9, and vice-versa.
Each computer system you communicate with can differ sign ificantly. It is important that you understand the format of the remote computer. Both systems must be set to the same baud rate (300) and the same duplex (either FULL or HALF). Note: If you want to establish communication between two AT ARI Personal Computer Systems, one modem must be in the ORIGINATE mode and the other in the ANSWER mode. Both systems should use the HALF-DUPLEX mode.
l I 6 CHARACTER CODES The software contained in the Telelink I cartridge converts some of the ATARI AT ASCII characters into ASCII characters . The following table defines the transmission of these special key functions . Keyboard Character Typed l EI 11mB l'mi.
Printable characters received by your AT ARI Personal Computer System are displayed on your screen as the characters defined by ASCII.
7 HELPFUL DEFINITIONS ANSWER MODE: This mode on the modem indicates which terminal is receiving the communication call. In the ANSWER mode you must manually answer the telephone and switch the ANS/OFF/ORIG control to ANS . BAUD: The unit measurement of communication speed, usually measured in bitsper-second.
