Unable to use terminal software

[DanW]

Hello, I am using a WiModem232 on an IBM Aptiva running MS-DOS 6.22. I'm trying to set it up for the first time, however whenever I load up a terminal program such as telix, telemate, kermit etc. i find that i can't type anything into the terminal once the program is loaded, unable to type in AT commands or anything. When I try to type nothing comes up. Was wondering if anyone else was having this problem as well.
