Setup a NULL modem network

Quick & Easy way to Transfer Large File from Atari to a PC

Large files here means files that don't fit into a diskette.

You need

    1. Atari - Zmodem software & HSMODEM v7.

    2. Windows - Zmodem software ( I use the one which came with Win95, HyperTerminal).

    3. A NULL-modem Serial cable.

    4. Optional: A TV set ( to relieve some boredom while waiting for the file transfer)


8 Easy steps to follow:

Misc settings

    • Configure RS-232 port to 110 on Atari for 115200 bps when using HSMODEM.

    • On Zmodem, you may need to

        • disable carrier detect ( -D).

        • increase receive & file buffer size (-b 16384 -F 5M).

        • disable multitasking on Atari to maximize response.


Last notes

On my system, Falcon ( 16MHz, 14MB ), I can achieve a transfer rate of over 10K bytes/seconds.

This makes it possible to transfer one Megabyte of data in about 1.5 minutes.
