I implemented LAT once.

The only public documentation I know about is pre 5.x microfiche
VMS sources.  Everything else is pretty much restricted by license,
and DEC closed down the fiche documentation as well when it figured
it out.

I assume you have a DecServer you want to use as a terminal server.  8-).

You will need a VAX to download the code to it as well, or you will
need to implement MOP and MOP-MOM to boot it.

It is almost worthwhile rewriting the download code (the thing is a
68k box, and you can cross-compile the code under BSD using GCC).


Typically, LAT is considered DEC proprietary and is unavailable without
a license.

I believe the DECServers, if downloaded by a VAX, will also support
non-LAT CTERM protocol connections -- CTERM is much easier to implement,
and you can buy the documentation for it and the underlying protocols
for about $180.00 for all the books you would need.


I don't think anyone is planning on reverse engineering LAT and then
releasing it publically any time soon; DECNet would be a nice thing
for BSD to have, though...
