Ah, I missed this one. LAT is the protocol by which terminals can talk to a
host machine (Local Application Transport IIRC) so you must be running a LAT
server on the host machine - LATCP is standard on OpenVMS and is an option
under Tru64/DEC UNIX/OSF/Ultrix. It's non-routable and is designed for
single office environments, so while it can be bridged over a WAN things can
get nasty.
To do what you're describing physically you need a mux, not a terminal
server. I don't recall RT11 or RSTS ever being able to run LAT.
"Reverse LAT" is when you have terminal ports like you describe (I only go
as far back as the DLV11J) connected to a DECserver at the machine end and
you set up virtual connections from those remote ports to local ports on
another DECserver at the terminal end - a kind of mux. The DS90L+ can't do
that unfortunately. You need a DS200/300/90TL or third party equivalent.
