You don't say what operating system you are using, which makes it necessary
to give (at least!) 3 answers:
The only VAX OS that I KNOW has a DLVJ1 driver is ELN. The ELN DLVJ1 driver
is NOT meant to drive an interactive terminal; it's used to talk to various
low-data-rate real-time devices that connect to an RS232 port.
There is no supported VMS driver for a DLVJ1, nor have I ever heard of anyone
writing one. It would be a pretty simple thing to do, but the result would
not be very useful: The DLVJ1 has no internal buffering - well, one char-
acter's worth - which means that it requires a LOT of attention; you have to
respond to it QUICKLY, or characters are lost. General-purpose timesharing
systems are not designed to deal with that kind of device, and basically don't
do it very well.
I have no idea if there is a Unix driver for a DLVJ1. Probably someone has
written one, but for the same reasons it's not a useful interactive terminal
port on VMS, it's not likely to be too useful on Unix, either.
