I have a Televideo 912C and a General DataComm Gen Net Terminal Server. I
want to make these two machines talk to each other. I think it would be
really cool to be able to display a Trek game or something. But I have a
couple of problems. First of all, I'm mostly a PC guy. I don't know
anything about these machines. Secondly, I don't even think the ports on the
back of the Gen Net are RS-232C. If they are, there's a protocol problem or
something, because what gets echoed back isn't what I type. (I type several
characters before one is echoed, and the echoed character is usually an
odd-looking non-character.)
I don't know the password on the server, and I don't know how to operate its
control keyboard. Here's something else weird--you have to actually remove
the front cover to turn it on and off!
Here are some pictures of these machines http://mywebpages.comcast
net/fastluck1/Televideo.htm. Check out the terminal--it looks really cool.
Can anyone give me information on operating these machines, or point me in
the right direction?
Thanks in advance,
John

If you give Google the name of the terminal and tell it you're feeling
lucky, you will be.

Sorry, I know nothing about the terminal server. Have you tried changing
the baud rate on the terminal?

Since we're talking about Televideo terminals here, I think I'll pipe up with my
situation.
I have a Televideo TS-800A workstation, wihch IIRC is basically a TVI-950 with a
daughterboard containing
a Z-80 CPU and an RS-422 serial interface for a floppy disk. Apparently this "dumb
terminal" could also
run CP/M for some basic tasks.(?)
Unfortunately, I too do not have the manuals for it. It's been a while since I played
with it, but I
think I was able to set the serial line parameters (baud rate, word length, parity, stop
bits). I
remember connecting it to the RS-232 port on the back of a PC running a VT-100 emulator
and I was able to
type text across both ways.
Does anyone here know where I can find some documentation on this terminal (setup, escape
sequences, etc)
so I can do more than just type "hello world" on this thing? I'd also like
to try out the Z-80
daughterboard, but I don't know if I need to first find an RS-422 floppy disk drive,
or if the terminal
can download it's bootstrap code and OS right off the serial cable.

IIRC, it would download its OS from something like a TS-806 or TS-816
located at the other end of the RS-422 line. My dad's practice (he's an
optometrist) used to have a bunch of the things before the TS-806 died. I
used to have a manual for the TS800A, but that got tossed out at some
point unfortunately :(, probably when my parents moved. The TS-8?6 would
then run some sort of database server usually, and serve
data/disk/printer out to the diskless TS800A's
Thanks to Don Maslin, I now have a TS-816 that I need to work on
resurrecting - the hard drive was crashed when I got it, and it's tape
drive (it has no floppy drives) needs at least a new tape-present lamp.
