escape characters

geir_2 — Thu, 24 Feb 2005 05:02:46 GMT

Hi,

For many years ago, when I worked with VMS, I had a paper with usefull escape characters. These could be useful if you want to configure scroll bars, double size, hight, cursor position etc on a vt-terminal.

It would be great if someone could help me to find the escape characters. If you have some examples it would be great.

Thanks!

Please check out www.vt100.net, there are a lot of manuals, esp. the programmer manuals contain info about all esacpe sequences.

Geir,

As well as the link Karl suggested (an excellent
site) you may want to look at the SMG routines
available. The advantage of these is that they
offer some degree of device independence.
There is a manual available at
http://h71000.www7.hp.com/doc/73final/5935/5935PRO.HTML
This of course assumes use of a language capable
of calling SMG. Using DCL will require knowledge
of the escape sequences.

Regards
Dave

Hi,

thanks for the asnwers.

Look at the following links:
http://www.vt100.net/docs/vt100-ug/chapter3.html#S3.3.2

The answer is:
ESC [ Pn; Pn r

The first parameter is the line number of the first line in the scrolling region; the second parameter is the line number of the bottom line in the scrolling region

But it still does not work. I don't know why.

Thanks again

Geir,
[n;n r is a level 4 code which is valid only for VT400/VT500.

Hello Geir.

You can also find this data inside the VMS itself.
Take a look at the file sys$system:SMGTERMS.TXT
