Unable to correct typing mistake from the console.

[Choowie]

Hi there,

I have a Perl script which I launch from a serial port console. The scripts
asks for a bunch of questions and then modifies configuration scripts. I use
the <STDIN> functionnality to read what the user typed in.

The problem is, when in serial console, I must not do any typing mistake.
The Delete of Ctrl-H key do not operate.

What should I do to have these keys working?

Thanx for your help.

You need to set the erase character correctly for your terminal using stty.

man stty

You need to set the erase character correctly for your terminal using
stty.

man stty

IMHO, the stty is set correctly. The Delete or Ctrl-H key work perfectly in
shell. It just doesn't work anymore within the Perl script. Do you think I
would still need to investigate on stty?

I did investigate further more. You were right
The trick is to have a "stty -F /dev/ttyS0 erase ^h"

Thanks.
