I've just recently aquired my *own* PC, rather than fooling around with the computers the school so nicely lets me use. Here's the question: How do I set the DTR line inactive after some terminal program has finished with the serial port? Here's the reason: I have a 'black box' I built about two years ago (when I was still living in a dorm) that switches an RS-232 line according to the state of the incoming DTR line on two ports. This lets my roomate and I share one modem, and have automatic null-modem if we both bring up comm programs. Now that I have two computers of my own, I want to be able to do this again. However, PC's don't appear to kill the DTR line when the port goes inactive, (Maybe it's the program I'm using. Any ideas?) which means the PC grabs the port forever after I use the modem once. Please *mail* me any answers you may have, and I'll sumarize. Dave Williams dawill@hubcap.clemson.edu "Huh? What? Could you repeat the question?"
