We are having many mysterious problems with programs that seem somehow
related with the V4 terminal driver. Here is an example.

We have ported VI to VMS. It works fairly well and the bugs remaining are
well defined. Bringing the source over to V4, changing the terminal interface
to what DEC says to do (using passthru instead of passall, setting ttsync, etc.)
and recompiling introduced problems.

Sometimes the terminal doesn't have echo turned off. Sometimes PASSTHRU mode
isn't turned on. Then suddenly one day without any changes in the code ECHO
and PASSTHRU always were set properly. The system wasn't rebooted between
when things didn't work and when they did.

Is this something wrong with the V4 terminal driver or am I having problems
with the C compiler and run-time? Anyone have similar problems?
