ZyXEL MODEMS AND ATARIS

All external models of the ZyXEL 2864 series may be connected to Atari comput-
ers. The factory settings should work just fine with your Atari computer.

Cable

The standard Atari ST, Mega ST and Falcon 030 models provide just a single serial
port, while the Mega STE and TT are equipped with 3 or 4 serial ports. Not all
ports provide all of the signals which are needed for truely reliable communication.
On the Atari ST, the port is a male 25-pin connector. On the other models, it is a
male 9-pin connector.
