ATARI 830 Modem

The ATARI 830 Modem is a Bell 103-compatible modem that enables you to communicate over the switched telephone network with another terminal equipped with a similar modem. The ATARI 830 Modem requires an ATARI 850 Interface Module that is used in conjunction with it.

The modem usually connects to port 1 of the interface module. The modem, under the control of the interface module, produces tones that are sent out as electrical signals over the telephone lines. Messages are received by the modem as tones that it decodes and sends to the interface module. The incoming/outgoing traffic is managed according to the programmed functions of the interface module.
