Thanks, Wirt -- lemme elaborate a tad:
We have this thing (a Hitachi 704 "Chemical Analyzer" for anyone who
know about 'em) working on a 969 running MPE/iX 5.5, and are now trying
to test it on a 918(6.5) prior to upgrading. Accoring to Those Who
Know, the instrument requires ENQ/ACK, and when we migrated from a
948(4.5) to the 969(5.5) we (apparently) had to write a little TTUTIL
file to make it happy. Looking at that same file, I see that it looks
like it was just set up to not expect or send anything (NULLs
expectation/xmit) so maybe this was the way around the handshaking
issue.
So now we're trying to figure out what why it doesn't work on 6.5 with
precisely the same terminal set-up and DTC configs. The mention of
ENQ/ACK came up again, and now after further investigation, I'm
scratching my head and mumbling. (Common occurrence, of course, just
more pointless in this particular case.)
Suggestions? Anybody?
Thanks,
Curtis

I'm nearly 100% sure that the ENQ/ACK protocol went away with the
arrival of
the first RISC machines and simply doesn't exist any longer.
