Anyone know much about HP terminals (700/96) I have this beast hooked
to a serial port on
my linux box.. I am using a "serial laplink" cable and a null modem
adapter (that should be
two null modems together) I have agetty lines in my /etc/inittab
s1:2345:respawn:/sbin/agetty -L 9600,19200 ttyS1 vt100
s2:2345:respawn:/sbin/agetty -L 9600,19200 ttyS2 vt100
The terminal is set at 91200 and set to emulate a vt100..
I am not sure however if the terminal is "online" or not
Where is that switched? (does online or local make any
sense for a glass tty with no local storage)

There's a function-key label, "REMOTE MODE". You may have to get the
right function-key label set up to see it (play with User and System
keys). "REMOTE MODE" should have an asterisk (*) in it. If it
doesn't, press the corresponding f-key. It's been too long since I
used one of these to remember what keys you use.
Yes, taking the terminal offline makes sense, at least in HP mode; you
can do local editing of the on-screen data and then use the ENTER key
to send it back to the host once you go back online. I used to do
this all the time on the 264X terminals.
BTW, the terminal is DTE. You probably want one null modem between it
and your Linux box, if you can't be bothered to work out the pinouts
and make the right cable.

did the 264x terminals have a little HP tape drive along the bottom
of the display?

My eyesight has gotten pretty poor, it's hard to see those solder cups
on the db25's Once I got this working I would probably make up a cable,
but for now I will use the various nice molded cables I have in various
combinations..

My first worry is that if it's a normal terminal it'll be a DTE (I've
never met a terminal that wasn't wired as such, for obvious reasons!) and
a PC serial port is normally a DTE too. You need 1 null-modem between them.
Get a breakout box (or even one of those little adapter-with-LEDs
testers) and find out which pins the terminal and PC are using as outputs.

Victory over terminal!!! Well sort of.
Yes, it's only one null modem. I have now a 9 pin straight cable+null
modem adapter+genderchanger
and It works. I think I am missing some handshake though.. when I put
the terminal in smooth scroll
it looses characters when I list things or print out something that is
long. Everything works fine
in the faster jump scroll. Just not as pleasing to use.
Part of the problem was finding the one of 3 serial ports on the back
of the computer that was really
live (yes I built the computer, but that was a year ago) :^)

Either a missing hardware handshake or a missmatch between hardware and
software (XON/XOFF) handshakes.....

I have a 700/96 term at home on my D230... We also have a flock of them here
at work on HP9K N-boxes. I believe that by default they are set for ENQ/ACK
rather than XON/XOFF.

EnqAck is also set to YES - perhaps is overides? I'll set it to NO.
hmm nope that didn't do it. Xon/Xoff are control characters.. If I can
interact with the computer then they should work.. ^s and ^q stop and
start
output... hmm

The "pleasure" of smooth scroll wears off.
Anyway, yes, the terminal can be made to do XON/XOFF flow control, but
it will be better for you to figure out the wiring and configuration
to use the RTS/CTS and maybe DSR lines for hardware flow control and
tell the terminal to do that. Then you'll be able to use Emacs without
kludging around having used C-s and C-q for flow control. (That religious
battle is on-topic here, isn't it?)
