vt220/ANSI terminal programming

[A. Daniel King_1]

I'm trying to use ansi escape sequences to save and restore cursor positions on a vt220 terminal. I understand that I get:

[s - for save
[u - for unsave (or restore)

For testing, I'm calling printf from the HP-UX command line like this:

$printf "\033[s\033[HTEST\033[u" > /dev/pts/tw

The TEST text comes through fine, the change to the home position works, but the save/restore fails me.

Ideas?

Thanks in advance!

Hi:

Rather than rely on hardcoded terminal codes, you should avail yourself of 'tput'. have a look at the man pages for 'tput(1)'.

Regards!

Very cool with tput. I'm now pass-through printing, too (tput mc5, tput mc4).
