Actually I seem to recall (could be wrong, though) that LA36's were current 
loop, and could not talk to a standard modem. You would probably need an LA120, 
or (slower) LA70(?)
I remember the RDM on a PDP 11/70 - DEC could only dial in if we switched from 
local to remote console (IIRC a rotary switch on the front panel)
