In one of your past messages I've seen the output of one of your MONGENs, but
had no time to check it. The only thing I've noticed is that there seem to be
no defaults provided by the program itself, or at least not in the help text.
MONGEN for 7.04 monitors is somewhat different because it was simplified and
made more clear, but the relevant settings are still all there. The following
is the output in MIC format (that is an executable script) of my standard
MONGEN which works flawlessy. I do not remember anymore where I took values
from for parameters where no default is used, anyway it does its thing. I have
not forgotten everything, so if you have questions try to ask me. :)

Thanks - Dave already sent me V3.3A BL40. Is yours the same version?
It's the same size .SYS file as Dave's.
And FWIW, I can report that you can indeed define services on the DS200.
I did manage to get it working as a console server for the PDPs, although it
took a bit of fiddling to get all the settings right. Hint: be sure to
define the port as ACCESS REMOTE. And it looks like you also have to set it
to AUTOBAUD DISABLED even if you define a baud rate.

I didn't think a DECserver could do this (or at least not an old,

Hello!
I'll say. I have a collection of 90L-Pluses here. Getting them to work
is an interesting problem. I'm basically trying to find the rack that
they use to enable a more normal Ethernet connection to them, but it's
slow going.
If you have a collection, i'll take one! ;)
Also, did you ever get those SCSI controllers to work?

Upon further investigation, the problem is with OPR.EXE. It WILL NOT
execute on my generated monitor. The one provided with TWONKY works fine
though.
.... Make sure that ORION and other Galaxy processes are all there and that
none of them shows a "^C" or "TO" status (IIRC). Also compare processes
between TWONKY and your installation and see if there are any differences.
It looks like I'm not linking something in to the monitor or not enabling
a certain feature. It'd be helpful if TWONKY provided the output from the
MONGEN dialogue...
OPR is just a client that talks to a daemon process so maybe it just stalls
because the daemon is not working, not responding, or not there.
Compare contents of SYS:SYSJOB.INI too.
HTH,

Not sure what I'm doing wrong as to what's keeping it from...doing anything. (I'm fairly certain what's happening is that it's not outputting to CTY)
