How to check com ports?

[Aaron1100us]

I have a cable plugged into my one and only serial port in the back of my computer. I'd like to know which com port it is and find a way to see if it detects the cable I have plugged into it.

I'm trying to program a ham radio using a cable that plugs into the radio and plugs into the serial port on the back of my computer. My computer does not see my radio. I don't know if my cable is bad or if I'm not using the right com port. The radio program needs to know what com port you are using, 1-XXX. I have no idea what com port # I'm plugged into and if it even works.


Is there any way I can test all this and know what com port is what? Thanks

You should be able to get the COM port number from the BIOS. Most likely, since you only have a single one it will be COM 1.
