Does anybody out there have a callable routine which will
return the status of a printer connected to a Vt1xx or vt2xx?
I don't want to have to re-invent the wheel if I don't have to.
-Thanks

If I recall, I had tried this once. There is a major problem with
the VT1XX series terminals, in that the printer port is a one-way
port, i.e. IT DOES NOT EVER READ ANYTHING... If you have been trying
this with the same results I had you would find this out.
Somebody correct me if I'm wrong, but I think the same problem exists
with the VT2xx terminals too.
I had written a major DCL procedure which would do setups for an
LA50 or LA100 connected to a VT1xx/2xx series terminal. I did the
entire escape sequence for the status checks (see the LA50 programmer's
manual) and I was getting baffled about the lack of response from
the printer. The printer port definitely does not listen to much,
if anything.
Anyway, the only way you can check status of a printer that I know
of is to have it connected directly to the host machine (i.e. spool
it).

Send the "Who are you" sequence and receive the reply via $QIO read and writes to the terminal. You will need to specify PASTHRU as a function modifier on the read. Cheers, Ciaran. | |||||

I tried that quite a while ago on a VT125. All you get back
is the escape sequence for the VT125, no matter the "print controller"
mode. I don't know for sure what happens on other terminals - I
think that you get the same results.
