Catching Bits In BASIC
I own an Atari 1040ST. I would like to know how to accept data bits through the parallel bus using GFA BASIC or assembly language. Are there certain POKEs that I can do for this?

It's quite easy to do this in GFA BASIC. Here's a short program that reads a byte from the keyboard and displays it on the screen. Any other input device can be read in the same way; just change the device number as indicated.
device = 2 ' device = 0 Printer Port ' device = 1 Serial Port (RS-232) ' device = 2 Keyboard ' device = 3 Midi CLS DO IF INP?(device) THEN a = INP (device) PRINT CHR$(a); ENDIF LOOP
