I have a receptionist that is operating with Two PCs attached to two separate Executone/Isotec phones via the Serial Ports on each machine. One is an old Dos machine from the original set up, the other is her current Windows XP machine running TMC in a console window. I am thinking that if I install an additional Serial port in her current machine, I could actually have both phones connected to one PC and answering in two different console windows. The only thing I am not sure how to do is how to tell TMC to use a port other than COM1. Is there a configuration file somewhere in the TMC directory that specifies which com port to use? If so, is it listed by the port name or the IRQ address or what, because I have not been able to find it.

Thank You.
