Dell PC --> Sun 4/150 serial link problems

[Brian Wolfe]

This is for a friend of mine who doesn't have usenet access...  I posted
this a few days ago, but our comp.sys.sun newsgroup is unreadable so I'm
not sure if this made it through.

If some kind soul could forward any of the helpful articles to me via mail
I would be eternally grateful.

Thanks in advance,

Brian.

Brian,

I need to connect my DELL 200 (AT-clone) to ttya (or b) on my SUN4/150.

I'm using PROCOMM as a terminal emulator with VT-100 turned on. Also
using: 9600 * 7 1 where * is various tries at parity. Also, using a 9 to
25 pin expander for the puny serial port of the AT. Have also tried with
and w/o a 3 pin null modem.

SYMPTOMS: When using the null modem, 9600 O 7 1, I am able to logon to the
SUN, but am not able to see any echo of my activities. That is, the
terminal (PC) screen remains dark.

DIAGNOSTIC: Last week I plugged an H19 into ttyb using the 3 pin null
modem and it connected perfectly.
