You're talking about connecting one RS-232 connector on the radio to two COM ports on the computer, right? You need to think about which lines are driven at which end. TxD, RTS and DTR signals are all created at the computer to be read at the other end; connecting line drivers from two different COM ports to the same receiver on these lines might not work. RxD comes from the radio to the computer; splitting it out to two COM ports might be OK, but wouldn't serve any purpose.
I think it'd be safer just to route DTR and RTS to one COM port and leave its RxD and TxD unconnected, and route TxD and RxD to the other COM port and leave its DTR and RTS unconnected. 73, Rich VE3KI W4AFP wrote: > Do you think there would be a problem in letting both signals pass > through to both COM ports?
