[fa.info-vax] DECnet and remote terminals...

From: Kevin Carosso <engvax!KVC@cit-vax>

Unfortunately, there is no way to get disconnectable terminals using
DECnet's SET HOST at the present time.  The RTDRIVER does NOT use the
standard TT class driver, but instead contains a lot of duplicate code
to perform the functions that the TT class driver performs.  Unfortunately,
not ALL the code is duplicated, and this includes the disconnectable
terminal support.  (At least, this is what I have concluded after looking
at the drivers a bit.)  I think that the way SET HOST works precludes using
the VMS terminal port/class driver mechanism to create network terminals
that are identical in functionality to "normal" terminals.  This means that
the RTDRIVER tends to lag a bit behind the TTDRIVER.

At DECUS, someone from DEC did mention that VMS 4.2 contains several
enhancements to the DECnet remote terminal support, but I heard no specific
mention of what those enhancements were.  With any luck, they will support
virtual terminals.  Again, I did NOT hear that disconnectable remote terminals
were in 4.2, I'm just hoping they are!  (just in case anyone misreads this)
