How do you find out if a comm port is already in use?

[tobie]

How do you find out if a comm port is already in use before you switch to that port. I am using a script that switchs between many different piece of equipment, and I would like a way to find out if the port is already in use before the script tries to switch and hangs on port already in use.

Thanks

Unfortunately, I have not found a good way to do this in ASPECT, primarily due to Procomm talking to the modem through the TAPI layer. At

I have a script called CheckModem.was that I've used in the past and seemed to work OK. Note that it only works with modems as direct connections do not support the commandmode on command. aspect@aspectscripting.com
