Thread: Is there a program that can read used com ports?

I'm not sure if it's possible, but have you tried monitoring it with HyperTerminal?

Here is a short for you. I am not 100% sure if it work, but by logic, it should.
Xport3. Yes, that right because all it does is create a multiple virtual port of a "real port". Connect phonco to one port and hyper terminal to the other port and monitor.

My phone is not here with me, otherwise I'll test it with xport3 and virtual port.

i tried xport but it wont do what i need. I cant send a port to another virtual port its gotta read from the original.

How about this http://www.kmint21.com/serial-port-monitor/
I just google for comport sniffer and that is one of the link.

Just make a Y-adapter that routes the data to two physical COM ports. The second port would not be able to 'talk' or transmit to the phone, just listen in. You could use HyperTerm (gag), TeraTerm, or similar to capture.

As long as the second program only monitors the RxD line, and can't transmit to the phone thereby confusing it, then it should work. We used to do it in the lab years ago.

Okay I looked up the pinout to make sure. Just connect pins 2 (RxD) and 5 (ground) from the incoming DB9 connector to another.

You can buy the DB9's at Radio Shack or similar store and build it, or if you have two serial cables laying around that you don't use anymore (one should be wired as straight-thru rather than null modem) then you can hack something together using those.

again the splitter wouldnt work. But zorro fixed what i needed the serial duplicator for. thanks
