I need to send simple signals through the parallel port of one windows
machine (which displays stuff in a screen) to another (which records
signals from a person viewing the screen). I can open or close the
parallel port using
open file "LPT1:" for write
close file "LPT1:"
The open command gets through to the receiving machine. However, when I
try to write data to the parallel port using
write ... to file "LPT1:"
the machine hangs and requires a shutdown before it will respond
Any help would be greatly apprechiated.
