Either that, or the port is broken. I seem to remember mine breaking a
couple of times, and me repairing it. But any further details have been
forgotten. I only remember that it wasn't hard to figure out or fix.
I assume you have tried shorting pin 2&3 of the serial port, and nothing
happens when you type...?
Open it up. There is a large board at the bottom which if I remember
right, is pretty much all of it.
Oh, I should mention - I don't remember there being more than one rotary switch for speed selection, but check to make sure there isn't a separate for Tx and Rx, and them being set differently for split speed...
Just out of interest, how hard would it be to get hold of this TRAX software platform that uses VT62 in it's block mode (it runs on "high end PDP-11s")?
Anybody ever program anything for it?
I've never seen or heard of anyone using it. I think it was available a very short time on the market.
It is mentioned in one of the processor handbooks that covers the 11/70, but basically no other DEC documentation even mentions it.

Is it possible to use say Arabic or Hebrew script on VMS - I don't mean for DCL of course but for editing text files etc.
Or does this require DECWindows?
VT240, VT330, VT340. All are glorious, and all are here.
Glad to hear. I bought a mint VT340 last week after watching it for months on ebay. Maybe I overpaid for it? ($200), but Im in Australia and they just dont seem to turn up that often.
I have an VT420 courtesy of Saku Setala but unfortunately the screen barely works so I've decided to try something else on my client box (OS X):
1. Terminal.app emulates the display side of VT220 etc very well
2. The problem is sending keys like the keypad and PF1-4, DO, HELP etc
3. However, Terminal.app lets you map any key to any escape sequence you want
4. So I'll purchase a full size Mac USB keyboard, print some labels (PF1, DO, etc) create a Terminal.app profile that sends the relevant control/escape characters on the newly labelled buttons and I should be pretty close to having something resembling a terminal with an LK keyboard.
The beauty of this is that it's light and will work with my laptops without a problem.
If I get this working I'll post the key mappings for Terminal.app on my website for any other OS X users here.

I know I'm in the process of being hooked up, but I think it will be great to be able to access DECUS via DECnet. Does anyone offer a news feed via HECnet?
Regards,
Daniel.

What can be done (non-destructive suggestions only, please) with a
VT-62? This is NOT a VT52 (although it looks like one). The VT62 is a
block mode terminal that, I think, actually speaks DDCMP. AFAIK it's
incapable of being a plain ASCII terminal unless there's some hack I'm
unaware of.
Have you tried it? I had a VT62 on my PDT-11/150 in college and I know
there was supposed to be a block mode, but it also worked fine as just a
VT52 clone, but with a speaker for keyclick/^G instead of a clacker, ESC T
switches you to reverse video and ESC U switches you back, and after column
72 there are tabs at every column. Other than that it's exactly a VT52 IIRC.
No idea if mine had been jumpered or had the ROMs switched or anything
to make it so normal. I bought it from an ex-DEC-employee (DEC dumped
a lot of the PDTs to their own employees) and I suppose it's possible
he got a special version.
I used a VT62 for more than 10 years in the late 80s and early 90s. Yes, they work exactly as you write, John. VT52 compatible, but with a different BEL sound, and capable of inverse video.
I wrote a termcap entry for it, but I'm not sure if I still have it around.
If they were capable of block mode, then it must be as Lee wrote, there must be a switch somewhere inside for it. Mine worked like any asynchronous serial interface. Plain RS-232. Not sure about any modem signals, but doubt it. Didn't run too fast. 9600 bps max maybe?
