Very Computer

Hello,  I'm in the middle of a small personal project and I need to know
what all the escape codes for the Digital VT-100 terminal are so that I can
catch those and emulate the effects on my PC (can you guess I'm building a
communications package?)

Anyways, I'm sure the complete listing of VT100 codes is documented and is
available in public domain via FTP but I don't know what the name of such a
file would be.

Could somebody please tell me where to find this information?

Thanks o'bunch

   I know you've probably gotten many of these requests but
when you get the file (or the address) could you please forward it
my way.  I'm looking for something like that to make some animation
files. and they're difficult to find..i have a couple (2) but that's it
i can clear the screen and the other screws up your characters on a vt100.
that last one crashes my home computers comm program but works on the
vt100, on the mac it just ignores it.
see ya

Ths will have more escape codes than you'll ever need...

it's called a torture test for vt100's and it does about everything
and even documents itself on the screen.

It's at the ftp site.....irisa.irisa.fr

and in the subdirectory  /pub/vt100

it's called torturetest.vt

there are also many others available from there.

NoNoNoNoNo.  I want a LISTING of what escape sequences do what on a vt100,
not a list of escape sequences for a vt100.

I.E. something like...

    (ESC)[;H(ESC)[2J    will clear the screen and home the cursor
    etc, etc...

right now I'm working with termcap and /etc/termcap but its a little
cryptic to figure out.  I wish I could get my hands on a DEC vt100 terminal
manual that is more like what I want.

thanks,

The VT100 escape sequences follow the ANSI X3.64 standard, which you
can order from ANSI (212 - 642 4900), resp. your national standards body.

Until the next Great Disk Space Crunch, a file containing a summary of
the control codes of the ANSI standard "X3.64 -- Additional Controls for
Use with the American National Standard for Information Interchange"
is available for anonymous FTP from the host CS.UTK.EDU  (128.169.201.1).

The file is:

    pub/shuford/ansi_x3_64.txt

There is a companion ASCII table:

    pub/shuford/ascii_table.txt

If you really want to understand all the codes, you'll still need to
read the full standard, but perhaps this will help you get started.

There is other information of potential interest in this directory,
gleaned from various network postings, certain archive sites, and
things various people have sent me.  The information is by no means
exhaustive, but perhaps it may help you get started.

        I guess they should be able to get you a copy or two?! Afterall, DEC
_DID_ support VT100 on their DECstations. Right?! Maybe they will put the
VT100 on the list of supported terminals on their Alpha box too! :) :) :)

But in the mean time, hope this would help!!!

NOTE:   Most of the escape sequences have defaults for the parameters,
        if the values are outside the range or omitted.  The action is
        not necessarily the same for out-of-range parameters and for
        omitted parameters, but it is usually not `the sequence is
        ignored'.  For example, in the cursor position sequence, the
        default for the row and the column is 1, if either or both of
        these is 0 or omitted.  But if either one of them is greater
        than the number of rows or columns, then the cursor moves to
        the last row or column (as appropriate).  Likewise for the Set
        Scrolling Region sequence;  if the row and column are omitted
        then the effect is to set the entire screen to be one scrolling
        region, NOT!!! as some emulators implement it, to ignore the
        sequence or, worse, to set it to a 1-line scrolling region (!!!).

One minor pet peeve.  An awful lot of the VTxxx emulators out there don't
really emulate a VT100 very well - this includes a lot (probably _most_)
of the commercial products.  I know that it can be tricky to get all the
little details right - I've written them myself, but I _do_ wish that
anyone who is writing one of these things would get hold of some copies
of the VTxxx torture test/demo files and try running them through their
emulators.  You may be surprised at how poorly a lot of the emulators out
there handle the little details ... some of them are so bad that they are
not really useable as VT100 emulators;  they are more of a satire on a
VT100 than a real emulator.

| Try to get a copy of the "Terminals and Printer Handbook" from DEC.
| It has a number of appendices which cover the various terminal models
| and their escape sequences.

Various people have suggested this and a number of other sources for the
information.  What I'd really like to see, though, is a list of all the
*undocumented* escape sequences, and what they do.  I recall that there
are several which will make various flavours of VT10x terminals do some
truly bizarre things.
