But we have hit one snag that is just...weird. Either of the two
RSX-11M-PLUS machines that we've tried (an 11/70 and an 11/53) both do
this. From one specific terminal server, when we connect to the LAT
service, it gets a connection (and LCP shows it as connected) but there
is no login prompt. It is completely unresponsive.
The other two terminal servers work just fine, and other machines
(several VAXen, two Linux machines, etc) can connect to that LAT service
just fine, meaning we get the ">" immediately and can log in.
My RSX-11M-PLUS configuration for LAT is bog standard (and all my
LAT services are in group 0)

I don't remember changing the Lantronix settings either

Do you have any thoughts on this?
Nothing springs to mind at this stage. In my "working life" I managed a fleet of
DECservers (200/MC, 90, 500), Vista VCP 1000 and Lantronix using TSM - and had these
operating on a campus LAN and with LAT bridged over slow speed WAN links (9600bps)
back in the day.
