Hi folks
I'm fooling around with some subs to get detailed cutting and chip to chip times independant of one another. I'm almost there, but I currently have a DPRNT function in one of my subs sending through RS232, it works fine in outputting my data, but my issue is, that I don't want to have my PDA (I'm using PDA for data collection) or anything else permanently connected to the machine, only when I want to collect data. But when program hits POPEN and DPRNT commands with nothing connected or drawing data, it bombs out with error '085 NO DR SIGNAL' on POPEN or if I connect device but don't have it 'sucking' for info or connect a blank cable, it hangs on DPRNT. Is there a way I can have my sub check for RS232 connection, and if nothing there, use a simple GOTO to skip POPEN and DPRNT?
Hope that makes sense.
Cheers
