I have a comment and a question.  

The comment: here at Wesleyan U., which uses lots of VT220's and VT320's,
the recommendation is always to set up the Communications Setup screen
with the Limited (as opposed to Unlimited) Transmit option.  Perhaps
changing your choice there (whichever you've chosen) _may_ help you stop
losing characters.

The question: may I assume that "calling at Trailblazer speed" directly
from the UNIX-pc is essentially error-free for you?  (This I ask because
I'm just now contemplating taking up Telebit on their 1/2-price TB+ offer,
for use with my UNIX-pc, and I don't want to have to run it at 2400 on
account of lost characters at higher speeds.)

Thanks for listening.	-- Fred (FLinton@eagle.Wesleyan.EDU) Linton
