[comp.terminals] Ser. term on Sun connected to VAX - problem

weinri@athena.cs.uga.edu (Kevin Weinrich) (06/15/91)

I can't make a terminal behave properly.  I have a CIT224
(DEC VT52/100/220 emulation) terminal connected by a serial
cable to a Sun 4/330.  At the moment, I'm emulating a VT100
(with "VT100 id" set) and my ttytab specifies a VT100.  I can
login fine to my Sun.  From there I'm using Sun's DNI
package to login to our local VAX ("dnilogin abc"), to which
we're connected through the ethernet, and from there I login
to a remote VAX ("set host xyz") which is connected to the
Internet.  All fine thus far.

Alas, when I then run the (Wollongong someversion) ftp
program, almost all of the response tromps over itself --
i.e., each line overwrites the previous one without
scrolling up the page.  That's the problem.

If I go to a (DEC) VT220 terminal connected by a terminal
server to the local VAX ("abc"), then "set host xyz" and
run ftp, everything works fine.  So, the problem is in
a) my terminal (I doubt it; I have the same problem with
a real VT220 terminal connected to the Sun or with using
Sun's te100 VT100 emulator window); b) the Sun (termcap?
ttytab? dnilogin?); or c) one of the connections between
my terminal and the *local* VAX.

Related problem (less important): I can't set my terminal
to VT220 (7- or 8-bit controls) without getting garbled
characters (e.g., "login:" looks like "&#n og*:", but
*works* like login) from the Sun.  This happens whether
ttytab is set to vt100 *or* vt220 (Yes, I am running
"kill -1 1" every time I change ttytab).  I was hoping
that setting the terminal to VT220 would fix the
main problem . . .

Any pointers to which FM to R(T) are welcome; I've tried
to RTFM, but don't know if the info just isn't there or
I'm looking in the wrong places.

Much appreciated,
