- EXAMPLE #2 SIMPLE NULL MODEM FOR 1ST TRANSFER IBM=>8-BIT
-
- This is just a quick and dirty transfer program I wrote. It uses
- a slightly different cable & will work for getting a real
- telecommunication program to the 8-bit. It'll transfer any file,
- including binary, BUT ONLY TO THE 8-BIT!
-
- First run this program on your IBM or clone to set the serial port
- speed.
-
- 10 OPEN "COM1:300,n,8,1,RS,CS0,DS0" FOR OUTPUT AS #1
- 20 CLOSE #1
-
- After running it type SYSTEM & hit RETURN For transferring stuff
- you'll just run the Atari program;
-
- RECIEVE.LST
-
- Then use MS DOS "COPY FILENAME COM1". After the clone finishes
- the transfer, just hit any key on the Atari to wake it up & save
- the program. I had to shut the screen off to keep the timing
- right. The IBM thinks it's just hooked up to a serial printer so
- it'll dump the file as is.
