 anyone has access to other working terminals, VT3xx/VT4xx in
 particular, I'd be most grateful if you would take a few minutes to
 run the test program. 
 I have a VT420 set up for my kid to play with.  I'll borrow it and
 submit a pull request with the results.
 
I have a VT525 in my home office that I use to read the mail (including
this and other mailing lists) when I don't want to fire up a workstation.
(It's quick, simple, and I get check/send a message without much fuss).
Would results from that terminal help?
