Using Hyperterminal to test null modem cable
Posted on 2002-06-05
I have a null modem cable connected to serial port of a laptop and going to serial port of NT server. I open hyperterminal on both machines and need to test connectivity of the two comm ports from laptop to server to verify they are able to communicate with each other. I am not familiar with use of hyperterminal. When I type in it no characters appear on either one. They both say they are connected and the lights on the null modem are all lit green, so i assume the cable is correct. In order to test connectivity shen I type characters in laptops hyperterminal shouldnt I see them on the servers hyperterminal program. ANy ideas what I am doing wrong or if I am even doing this correctly.
