Actually, given that all I want to do is display what the serial port is receiving, could I just do that in Apple BASIC? Does it have something along the lines of fgetc() ?
Applesoft could probably do the job fine, as long as the data rates weren't too high for it to keep up. GET A$ will get the next character in the string A$. It will wait until there is a character to get (which means you can't do something else while you wait). -michael NadaPong: Network game demo for Apple II computers!
