Despite the fact that every term program under the sun seems to support
Tek 4014/5, I cannot find a description of the control sequences anywhere
(just a reference to the termcap entry, but I want the *graphics* control
sequences, not the terminal ones). Does anyone know where I might find a
listing of them?
Until then, I'll use GNUplot ;-P

Yes. :-) I just dug up my Tektronix 4114 Display Terminal Operator's
Manual and found the following beginning on page C-4: List of Escape
Sequences; each escape sequence is listed alongside it's corresponding
command and setup command. For example:
Ec(I)(A)<int> Set-GIN-Cursor None
.
.
.
Ec(L)(X)<xy> Set-Dialog-Area-Position DAPOSITION
Is that what you're looking for? If so, e-mail me your snail-mail
address and I'll send you photocopies of these escape sequences.
BTW, Does anyone on this list have, or know where I can obtain,
service data for my Tektronix model 4014 terminal?

New subject: The Missing 6809 UniFLEX Archive
OK, for all I know everyone that is interested in such stuff already knows
about this. However, I just ran across this, and it sounds like something
of interest to some of the list members (basically because it's apparently
software for 6809 SWTP boxes).
Remember I've no idea what this stuff is.

::Remember that the original Tektronix unit was a vector display (not a
::raster scanned unit), so the whole thing is based on drawing vectors.
I was still hoping though! :-)
What I ended up doing was the same thing you suggested, sending the
vector twice. I made up a mini-"RLE" mode where it would turn a line
of black pixels into two vectors rather than a vector pair for every
point, and together with a contrast adjust that turned down dithering
it came out very well. It's not too quick but then neither is the
C128 or the Mac IIsi.
pnmtotek :-) is in Perl. I can share it with the list if
people like; it's short and a terrible example of Perl programming.
I'm sure people can improve on it; I'm just going to see if I can
turn it into C first. It takes any P6 portable anymap from, say
djpeg or NetPBM, and displays it in Tek.
::It would be a lot more fun to use a real Tekky terminal for this ;-)
Yeah, but when all you have is Commodore Kermit and a IIsi with
NCSA Telnet 2.6, you take what you can get ;-)

The Tek 4014 had a mode called "Point Plot State". In this mode, only the final
vector endpoints are plotted. You enter "Point Plot State" from "Vector
State" or "Alpha State" with the FS character.
Some Tek 4014 emulators do not implement "Point Plot State" correctly or at all,
so you may want to plot your points using normal "Vector State" commands. For
this, just send a GS character followed by the point location (dark vector) followed by
the point location again (light vector with zero length).

Tony,
I believe you are correct regarding the EGM. Thanks for clarifying that point.
Regarding the line length, I presume most users use "word-wrap" for their email
readers. This allows the reader to format the screen as desired (similar to the way web
browsers handle text). I believe all HTML compatible email programs have this capability.
The big advantage of handling email this way is that when the line lengths increase due to
the > or > > or > > > which stack-up with each reply, the email remains
completely readable and well formatted. (I'm sure everyone has received the email
which is littered with tons of > > > > > > > > > and barely
intelligible.)
If this is a general problem for other readers, let me know and I will add the line breaks
for any additional posts to this group.

The Tek 4014 had a mode called "Point Plot State". In this mode, only the
final vector endpoints are plotted. You enter "Point Plot State" from
"Vector State" or "Alpha State" with the FS character.
According to the manual, this mode (and incremental plot mode, etc) is
only available if you have an EGM (Enhanced Graphics Module, Option 34)
installed in the 4014. This appears to consist of an extra PCB (Discrete
Plot Card) and replacements for a lot of the other boards.
I think I could justify that a 4014 emulator need not support this mode :-)
Some Tek 4014 emulators do not implement "Point Plot State" correctly or at
all, so you may want to plot your points using normal "Vector State"
commands. For this, just send a GS character followed by the point
location (dark vector) followed by the point location again (light vector
with zero length).
This is the documented way to do it on all 4014s.

Tony,
As I said, you are right about the EGM. It was an option. No argument. I was only
trying to help the original poster.
Regarding this off-topic email issue, I say, "do whatever you want." I will do
things your way when I post here. But, I hasten to add that the comments I've
seen here make clear to me that I have failed to explain why wrap works fine
for me. I only get the > > stuff at the beginning of paragraphs. I can cut out
paragraphs and paste without the tedious editing. But, I repeat to eveyone...
"Do whatever you want."
Also, I never put any HTML in my email posts. But I receive email containing
HTML everyday. So how can you say HTML has no place in email? If you ever
need to imbed formatted data in your email such as a table or use any character
attributes such as color or bold, you need HTML. (Yes, you can use attachments
or use some other work-around, but that's rather inconvenient.)
Only my opinions.

Well, I've never seen one of these terminals, but that's what the manaul
says...

(similar to the way web browsers handle text). I believe all HTML
compatible email programs have this capability.
This is not meant to be a flame, but I am tired, so it may come out like
one. If so, I apologise.
HTML is a markup language. It's not strictly a formating language, and
IMHO it has no place at all in e-mail. Period.
Not all e-mail programs (or the editors that they call) have any
word-wrap capability. Of those that do, as soon as the reply-marking '>'
characters are inserted, it's essential to preserve line breaks so that
those markers always come at the left of the physical line. Otherwise the
mail soon becomes totally unreadable. Word-wrap therefore makes little
sense for e-mail.
