hyperterminal or analogue on OpenVMS

Alex Chupahin — Tue, 01 Apr 2008 12:15:35 GMT

Hello!
Is there a terminal emulator program for OpenVMS
to access any hardware (UPS switch etc) via null-modem cable ?

SET HOST /DTE

Try "set host /dte". For more options look at the VMS help for set host /dte.

Hello Alex,

Have you tried "$ SET HOST /DTE"? We use it in similar situations.

Hi Alex!

C-Kermit is probably the best you can get.

I use SET HOST /DTE (normally from a DECterm)
for interactive use (because it's always
there), and Kermit if I need to script
something (like restarting my Cisco 678 DSL
modem/router automatically).

If you could attach your serial device to a terminal server, you open up options such as TELNET or SET HOST/LAT. Lantronix still makes "modern" terminal servers ie. you wouldn't have to go to the wrecking yard and dig out a DECserver!

Still unclear.
This command should be followed by device name.
It is unclear what is the device for com port 0
/dev/ttyS0 in Linux notation.

Depending on the system model and where you have physically plugged in the cable, it's most likely TTA0:

$ SHOW DEVICE TT might help you.

hmm, still unuseful

I have fta2:. I'm not sure it is com 0.

I have no '@' key - cant press ctrl/@

C-Kermit is for transfer files between hosts via null-modem cable, isnt it?

No useful utilites such as minicom ?

Re: hyperterminal or analogue on OpenVMS

Art Wiens — Tue, 01 Apr 2008 17:45:18 GMT

Sorry, a SHOW DEV TT doesn't show them for some reason. Try a SHOW DEVICE TTA and SHOW DEVICE TTB. The built-in serial ports are usually OPA0: (but you don't want to use the console port), TTA0: and TTB0:

Compare it with your description of your
system model, which still rates at a perfect
zero on the usefulness scale.

> I have no '@' key [...]

What's Shift/2 on your keyboard? Perhaps
some description of _all_ your hardware would
be useful.

> C-Kermit is for transfer files between
> hosts via null-modem cable, isnt it?

Among other things. Perhaps you should
follow that link and read more about Kermit.

> No useful utilites such as minicom ?

Don't need any. As you can see, everyone
(else) does just fine with SET HOST /DTE.

Were you planning to ask how to build a cable
without telling us about any of the hardware,
too?

Re: hyperterminal or analogue on OpenVMS

Alex Chupahin — Tue, 01 Apr 2008 17:57:53 GMT

Thank you. But I have no TTA etc

I have
OPA0: Online 0
OPA1: Online 0
OPA4: Online 0
MPA0: Online 0
OPA2: Online 0
OPA3: Online 0

Still dont know how to send ctrl/@
I have pc-style keyboard without @
(symbol @ is generated by shift/2)

> Still dont know how to send ctrl/@

Oh. You must mean _this_ "Ctrl/@"

Press Ctrl/\ to quit, Ctrl/@ for command mode

Try Ctrl/Space.

WHAT IS THIS SYSTEM?

Re: hyperterminal or analogue on OpenVMS

Art Wiens — Tue, 01 Apr 2008 18:09:07 GMT

My ES47's don't have TTA0 or TTB0 devices either, but I also don't have a serial connector on the back of them either.

One more request for you to disclose a few more details of what kind of system you're working on.

How would minicom know what to connect to if you had it?!

I assume that it's psychic, unlike me.

> Ok system is Jensen [...]

And what's that? I don't know the project
code names. What does it say on the front?

What does it have for serial ports on the
back?

Are you using a DECwindows interface (with
a DECterm), or a real serial terminal?

Pulling teeth is easier than this.

> I cant see any command that help me with it

Don't say Ctrl/@, or, if you do, try Ctrl/Z,

Then start typing.

Let me guess. The cable doesn't work.

Fairly easy. Much more easy.
I setup serial device (ttyS0, speed) and
feyyuu - I am in the console of the device.
I dont understand why this very simple operation should be so complex in VMS.

BTW Jensen has two integrated RS-232 serial ports.
I just check on the Itanium rx1620 - have one serial RS-232 also.
