O/T Communications:

Off topic, Communications, I am the worst at this.

I was trying to read serial data from a Cognex camera, and I don’t seem to be able to view it.
I tried swapping Rx and Tx, but nothing...

I wanted to make sure that the USB to serial Com port is working, on my laptop so I ran Hyperterminal, and plugged a Loopback connector to my com port.
The Echo came back good, so I am sure that the Com port is working.
What I want is to be absolutely positive that I can get a signal from a known source, so I thought that I can connect two laptops together.

Is there a way to connect two computers through serial ports using hyperterminal, or RealTerm?
Do you need a crossover cable between them?
Thanks

You need a null-modem cable or adoptor. Because TX (transmit) and RX (receive) is reversed.

I used a 1747-CP3, and it worked great, so at least I know my Com port is good.
Thanks
