Gary,
Here's most of the SYS$MANAGER:SETUP_TERMINALS.COM we used on a
MicroVAX with a DHQ11. Port 0 was connected to a real modem, for dial-
up terminal access. We hardwired the speed; you shouldn't have to
with a telnet port.

Thanks, Mark. I was planning to try the VH emulation this weekend, in
fact. I'd held off because I wasn't sure I could use a Qbus device
with the Microvax emulator, and thought I might have to build the
11/780 emulation instead.
I have more information on the DZ, too. After much blind and random
experimenting, I found that using this command on the VAX side will
make the TTAx ports behave in a somewhat more predictable manner:
SET TERM TTAx -
/MODEM -
/DIALUP -
/HANGUP -
/DISCONNECT -
/NOAUTOBAUD -
/PERMANENT
Note that these settings go away when the VAX is rebooted, so they
probably should be added to SYSTARTUP_VMS.COM or some other script
that will reset them after a boot.
By setting those flags for each of the ports on the DZ, I get a
consistent result. The telnet session is completely disconnected on
logout, closing the telnet window, and no _TTAx process is left
hanging around on the VAX side. The remaining issue is some slowness
in getting up a prompt when first connecting, and that may be related
to what you've described here. I find that it takes 20 to 30 seconds
for the login prompt to appear after pressing the ENTER key, but after
that everything works well.
I'll give the VH a try, possibly today.
