I think I did before, but I confess I didn't spend much time on it. My
pride and joy was certainly the rewritten ei.c driver (implementing the
200-UT batch protocol), and the clever workaround to an egregious KRONOS
bug where it would get stuck in a POLL/REJECT loop (I merely sent a dummy
command viz "Q,I" -- discarding the response -- because KRONOS was
expecting a command instead of the correct REJECT being nothing to send
from the batch emulator).
At the time, Unix got blamed because the smaller non-Unix /40s (running a
standalone program) worked fine for some reason; my guess is that it
implemented the broken protocol somehow.
