I love the things, but the only thing I've found is DEC's DECW$TERM and piping this stuff over SSH just isn't the same as something running locally..
I fear DECterm is only thing that supported SIXEL/Regus graphics. Tek 4010/aka Plot 10 was popular, but by the time DEC did SIXEL, graphics terminals and workstations were already taking over and I don't think they got enough market share for 3rd party SW houses to support it.
I asked one of the original Athena guys if he remembers / knows of anything besides DECterm.

Could you expand on how it fails?
Duh, sorry!! Here's the most egregious case:
I've tried to muse a little, but I might be totally off base here.
As far as I know, the hidden wrap flag do exist on xterm, as well as VT200 and newer terminals. So I'm mostly curious about trying to figure out in which way it differs.
(For comparison I can mention that PuTTY does not, and it is one standing issue I have with that program, as I actually use this "feature" in a program I wrote (ZEMU to be precise).)
So I did stumble upon this many years ago, and thought I knew how it worked. Your comments about a VT100 failing, and relating this to that same flag is making me curious...
Also, it would seem that, according to your posting here, John, some letters are doubled on a VT100. Even more weird.
I should probably look at the actual stream of bytes coming in. But if you have any more light to shed, I'm really interested here. But we can take this offlist.

The old man was the first DEC reseller.
The old warehouse is still there. The son tried to get into the PC business in the late 80s and the shop that had all the cool old 'tronics in it closed, since the PC customers did not like the dirty and dark. Like John, other of us "nerdi" knights knew it as a holy place.

At the risk of being extremely stupid, I would also appreciate
being able to run the same tests - just for the sake of knowing
what is being discussed. However, as a simple PDP-11 fellow,
I can't run VMS stuff and all I found was source for VMS.
Did you run the VTTEST code using a PDP-11? If so, which
operating system? Was that a real PDP-11 or E11?
It was Brian's great-escape.tmesis.com setup (which is awesome!!!).
For E11, I used the undocumented (because it's too easy to trip up and the
lack of DNS is annoying) TELNET command in the DOS version (only):
; great-escape.tmesis.com
; log in with VTTEST (no password) to test VT100 compatibility
net start ether-0 dhcp eth0:
def key f1 = "telnet 24.187.213.28"+chr$(13)
def key f2 = "VTTEST"+chr$(13)
So start E11 with this command file, then press F1 to connect, and F2
at the login prompt.
For the real VT100 and VT101, I used Linux. I don't have a getty on my
COM port so I did "telnet </dev/ttyS0 >/dev/ttyS0" and once that started up,
"stty ixon </dev/ttyS0" from another console so that XON/XOFF is honored
(lots of SUBs without that, and if you do it before starting telnet, the
ixon flag gets cleared when /dev/ttyS0 is reopened -- I don't use stty
enough to remember the switch that makes changes stick).
Then "open great-escape.tmesis.com" on the VT100 and you're off.

The plot sickens ... I was starting to feel paranoid and wanted a second
opinion. So I replaced the UA9636/UA9639 driver/receiver chips in the VT101
that's been kicking around my basement for 10+ years waiting for me to get
around to that. Now it fails VTTEST too, but not the same way as the VT100!
(Characters only at the margins in the failing test, but with gaps.) The
132-col tests are all wrong but that's no surprise since the VT101 has no AVO.
Some quick experimentation shows that in the VT101, the rules are the same
as the VT100 ones above as long as the cursor doesn't leave the line where
a char was written to column 80 for the first time. But if it does (by any
means -- DCA, ESC M, <LF>, ESC [B etc.) then the "wrap" flag is cleared,
whether a printing character is displayed on the other line or not.
OK so DEC's *own* VT100 knockoff isn't even VT100-compatible. Nap time!

The target OS is immaterial. The output to the terminal or emulator to be
tested, however, is. You can run VTTEST by simply telnetting to my VTTEST
account at 'great-escape.tmesis.com.' Use the username: VTTEST There is
NO password needed as this is a captive account.
Did you run the VTTEST code using a PDP-11? If so, which
operating system? Was that a real PDP-11 or E11?
If a PDP-11 was used, is there a link available to VTTEST.SAV
(source as well would be even more appreciated if it is in
MACRO-11 or FORTRAN) so I can run the VTTEST code?
Jerome Fine
The VTTEST suite was written in C. Unless you have a C compiler for your
PDP-11s OS, your going to have to translate the test suite's source your-
self to Macro-11 or FORTRAN.
