> You will need to get another COM port. If you have a desktop computer, that is easy because you can buy a card to go into an expansion slot. Then you would have COM1 - COM2 - COM3 etc. Now you can also go with a USB to Serial adapter (Elecraft sells one) and then you can add addition COM ports with that do-dad. But, they do work rather nicely in a lot of applications. I blew up mine because of of some RF in the shack. Stopped working. I went with the COM port card. You can get a card with two or four COM ports for around 10 to 30 dollars.
