Hi, I have read the documentation but can't work this out. I have a radio which has a virtual serial port (COM8) that uses DTR to key the transmitter on and off. I need to re-direct COM8 to a physical port (COM1), and set DTR off initially. Then toggling DTR on COM1 will control the transmitter. I would appreciate any help on how to do this. Thanks, Graham
