I have two radios using two serial ports. I can switch between radios and all the rig control function work ok. I have CW keying via the serial port whick works well with one radio. I cannot find how to set up the second radio using the same type of interface cable using the second serial port. The only option I can find in the preferences is to use the LPT1,2,3 for the second radio.
The question is how do I set both radios up the same, using two serial ports for CW keying? Cheers John ZL1ALZ
