Quick & Easy way to Transfer Large File from Atari to a PC ( Windows ).

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: 
Step 1   Connect up the cable  between Atari & PC.
Step 2 Atari Install HSModem
Step 3 Atari Configure RS-232 port to max port speed.
Step 4 Atari Run Zmodem software on your Atari to receive file. (with -rz )
Step 5 Win Run Hyper Terminal & open the comms port.
Step 6 Win Configure RS-232 to max port speed.
Step 7 Win Select transfer files using Zmodem, select your files to transfer.
Step 8   Watch TV while waiting for file transfer to complete.

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.
