Well, that pretty-much answers that...<br><br>

...and this reminded me of one of the ways we used to run our VAXstations

I think it will all work (and someone please tell me I'm wrong if I've
mucked-up again):<br><br>
* I boot my PC with Linux running its own X GUI (and I assume this really
means an X server is running there... somehow).<br><br>
* I then run SIMH in an xterm window (or in the background - on a
console) which gives me a SIMH-based VAX host running on the same PC
(maybe including the 'throttle' thingo that was mentioned earlier in the
week to help ease the load? Haven't tried that yet).<br><br>
* Linux will already have a connection to the 'primary' network card in
the PC. I'll set it up with static IP, as that's just as
easy.<br><br>
* The SIMH-based VAX host is set-up (according to the original article)
to have a 'private' connection to the 'secondary' network card that's
installed in the same PC.<br><br>
* Connecting the 2 network cards via a crossover twisted-pair cable will
effectively give me a peer-to-peer network between the Linux environment
and the SIMH-based VAX host over TCP/IP.<br><br>
* Somehow, I run the DECterm image on the SIMH-based VAX host and specify
the Linux X display as the display device for the DECterm.<br><br>
This is sort of the flavour of what RickC's scripts and command
procedures seem to do... <br><br>
I have yet to install the 'secondary' network card in the PC... but I'm
just checking my thinking before I go to too much trouble :)<br><br>
BTW... What do we do about keyboard emulation? Using any of
the xterm/terminal software in Linux with VAX is a horrendous
nightmare... although I've managed to get the BS/DEL key working in
xterm; too many things to change in too many places... and I have
no idea about how the EDT keypad gets mapped.<br><br>
Anyway, many thanks for the help.<br><br>
