here's the "why", the port only connection can not be
translated.


The Lat architecture is built around the use of Service names. In nearly
all cases the Terminal server is the master and the VMS node (or host) is
the slave. The terminal servers collect service names advertised by
the hosts, and initiate connections.  If a host wishes to connect to 
a Terminal Server (T/s), then it can either look for a service being
advertised by the terminal server, or it can send a solict, inviting the
T/s to try and connect to the Vax.

Print jobs and LTA devices can normally point to either service names or
node/port combinations. The actual LTA details determine the kind of
connection request.


For inbound connections to a service, as they are linked to a vty we can 
easily remap them to a Telnet virtual terminal and carry out the payload
transfer from Lat to TCP. But for a host-initiated connection, the host
is asking us to make a connection from port x to the LTA device. Because
we are having to actually allocate the physical tty as one end of the
connection, we have no way of re-directing that datastream, so basically
our hands are tied.
