I tried this over the weekend and it works just fine.

There is a file /usr/bin/umodem that I assume contains the UMODEM code.
Based on that, I assume the ATE forks off a umodem process and connects
stdin and stdout to it. If that's right, then, theoretically, you could
put a copy of rz inplace of /usr/bin/umodem. The ATE wouldn't know the
difference. No, I haven't tried it but it seems like a safe experiment
(I guess the worse that could happen is that the ATE could crash) so I'll
give it a shot when I get time.

Even if that works, you still only have one protocol available in the
<Shift><Cmd> menu of local commands. Why oh why can't we get the source...
