Hi all,
For those interested in Sixels, I ported the code (quick and dirty)
from ftp://ftp.cs.utk.edu/pub/shuford/terminal/all_about_sixels.txt
to Javascript and combined it with Flot and a JQuery terminal:
http://rullf2.xs4all.nl/sg/sg.html
You then get a Javascript terminal, with a display function; some examples:
js> example$
js> display(example$)
js> display(Array(5).join('CA at ACGOG'))
js> display('HECNET')
and
js> display(digital$)
Considering the run time to display the latter image, photos should
perhaps not be too detailed...

The second part of this is actually making the files visible in the specific library. For this users need write access to the directory (and possibly extend access). In order to find the files, you need read access. For removing files from a directory, you need write access to the directory.
So obviously, you either allow both entering and removing, or neither.
That's what I ended up doing, I trust there aren't too many griefers on HECnet that'll go and delete random files.
But seriously, if you find something cool or want to post an image of yourself, send it to CHIMPY:[.DROPBOX]. I've got a few alpha EXEs up there and a couple of pics of myself in SIXEL and JPEG formats..

But some UNIX getty's DO speak Hayes AT so it's not that far-fetched an idea..
So, how do the Unix getty know that there is a hayes modem on the serial line, and not a terminal?
Config files and/or command line options - some of them even know how to pass FAXES along to a fax receiving program.
Not saying this should be in VMS, just that it has existed in the real world for a long time.

The only example of VMS speaking Hayes I know of is when using SET HOST/DTE
with something like a /MODEM=xxx qualifier and the corresponding user-provided
DTE_xxx.EXE in SYS$LIBRARY. See SYS$EXAMPLES:DTE* for more information. :)
OpenVMS VAX V7.2 has a couple DTE_*.MAR sample files, while OpenVMS Alpha V8.3
has a nice DTE_AT.C dialer. Maybe other versions have others and if I'm not
wrong there should be something quite useful in the DECUS libraries too...
HTH, :)

Would you expect VMS to spew out hayes commands when you connect a
terminal?
Actually the VMS dialer interface is well documented (isn't all of VMS
like that??) and long, long ago I wrote a dialer for Hayes modems. It lets
you use the SET HOST/DTE/DIAL=... command with Hayes compatible modems.
If you really need it I could probably find a copy.

Also, it wouldn't have to do it on EVERY port, something like SET TERM/HAYES TTA0: would enable Hayes phone answering on that port only.
That could definitely be done, except I wouldn't expect any answering as such done in any other way than auto-answering. It would be a bit silly to perform the answering manually, even though you could in theory do it.
Also, even though the Hayes command set is sortof standard, there are slight variations, which makes it rather tricky to do something generic.

Uh... Why would it? There is no difference between a modem and a terminal here. They both come in to the machine over a serial line, and then VMS expects you to log in.
Yes, the modem should be set up correctly, and then it's just a piece of equipment in the communication path, which is totally transparent.
The wiggling of the DCD is how a modem (or terminal) tell the computer that it is connected.

No, this is why I advice to set the modem up with sane defaults before hooking it up :)

Yeah, I'd hook up a terminal first, set ATS0=1 (autoanswer) and then store the defaults in the modem's NVRAM. That way the modem just raises the DCD line when a connection has been made.

Yeah, that's the way to go. I'm tempted to buy an ancient Nokia GSM phone, get a data number for it and a serial adapter, and plug it into my DS300..9600 bps dial up access, woo hoo!
I kinda still enjoy dial up... are there any active modems on 'the net'? Sampsa, you and I tried this once, a long time back... not sure if we ever connected, but I didn't have POTS at the time...
So if I install this thing (it'll cost me about 15 euros a month) how much use do you think I'll get (i.e. how many inbound calls).
Mark, this would be a great demo at various vintage events, ISDN over GSM talking to a DECserver that connects to a VAXcluster :)

I'll give it a whirl when I get outta work this evening (assuming time permits!).
I'll dial out with my Commodore 64 :)

You can try SLAVE which is connected via a dial up. Not tried it in a while but it should still work OK.
