stty undef

[Eric Malzahn]

We have several control keys that reek havoc on our system. Can I set these to undefined with stty? Namely, these are the intr and stop functions. I know how to change them, but how do I change them to be ?

Thanks!

Hi Eric:

See the man pages for 'stty':

# stty -isig

...will disable the checking of characters
against the special control characters INTR
and QUIT.

Regards!

From man stty:
control-character c Set control-character to c, where control-
character is erase, kill, intr, quit, eof,
eol, eol2, werase, lnext, min,or time (min
and time are used with -icanon; see
termio(7)). For systems that support job
control, susp and dsusp characters can also
be set. For systems that support shell
layers (see shl(1)) swtch can also be set.
If c is preceded by an (escaped from the
shell) circumflex (^), the value used is the
corresponding control character (for example,
^d represents Ctrl-d); ^? is interpreted as
DEL and ^- is interpreted as undefined.

Looks like ^- should do the trick.

HTH,
Pete
