WiModem232 on Apple //e with SSC no longer displays any output

Since you are able to send commands and have the WiModem232 respond I really think this is just a configuration issue of some kind.

I'm reasonably confident that it's a configuration issue as well, but all I've got is a bunch of Apple systems to test with.  I'm going to give another shot to figuring it out this weekend.
