Hi,

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 properly again.

Any help would be greatly apprechiated.
