But this WiModem232 works just fine on your Apple IIc, so it definitely is working correctly. There is a dip switch on the SSC that controls this. I made a note a few months ago about this very issue in the Apple IIe setup thread. Did you see this?:
*** NOTE *** IF YOU DO NOT SEE ANY RESPONSE FROM THE MODEM, ESPECIALLY AT 300 BAUD, TRY FLIPPING DIP SWITCH 7 OF SW1 (THE FIRST DIPSWITCH BLOCK) TO THE OPPOSITE POSITION!
This dip switch controls the output echo that is used by ProTerm and some other terminal programs as a means to know if the incoming characters should be sent to the display or not. If its the wrong direction you won't get anything output to the display, but everything works. Your system was working fine for a long time, and the WiModem232 works fine in your Apple IIc. Maybe your dip switch got changed or is dirty.
