We are upgrading our VAX 11/750 from 4.2BSD to 4.3BSD.  We
have both a DEC DMF-32 and an Emulux DMF-32 emulator.  Both
DMF-32's work fine under 4.2, but under 4.3 the Emulux DMF-32
is losing characters while DEC's works fine.  The problem occurs
at 300,1200,9600, and 19.2k baud, although less frequently
at lower baud rates.  The characters that are dropped are
somewhat repeatable, if I do an ``ls'' of my home directory,
the same characters are missing every time.  On the other hand,
with nothing running on a terminal but sysline, most of the time
it works fine, once in a while the first character of the message
is dropped.  We spent some time looking at the RS-232 control
signals and we are fairly sure they are not a problem.

Hopefully someone out there has solved this problem or can 
shed some light on it.

Thanks in advance,
