Simple, DEC terminals like to use Xon/Xoff flow control protocal
and will run ok without it if the baud rate is low enough.
You have two choices either hardware flowcontrol, or enable
and use xon/xoff. I'd suggest the latter as it's the common way
for DEC systems.

Subject: Attaching a VT100 to a PC....
OK, I managed to dig out a VT100 out of storage. Of
course the first
path
I burrowed all the way back led to a VT103, so I had to
dig an even more
difficult path.
Anyway, I've got it hooked up to the Intel 810e board I'm using for my
Desktop PDP-10 project. I've got Linux set so I can log in and do
stuff.
The terminal seems happiest working at 9600. Under
TOPS-10 V7.03 I can
do
a DIR in a small directory and everything is fine, but
if I run it in a
big
directory such as SYS:, then I get slightly garbled
data. Same thing if
I
run a SYSTAT, it's garbled, especially the last
part.
I'm not up on Serial stuff and I've seen simular results hooking up one
of
my VT420's to Sun Sparc. Is the problem my
cabling, or what? At the
moment I'm using what looks to be a LapLink cable (or the equivalent).
For
the finished project I plan to build a custom cable.
