Menu system with vgetty

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

I'm trying to develop a menu system using vgetty.

I've read through everything I can find in the source package, and it
appears that for me,
the best way to go is to set up voice.conf with a perl script as the
call_program, and
then do everything else myself.

Having decided to use Perl, I looked at the Modem::Vgetty module, and
tried to use that.
Turns out that the useful bit is pretty seriously broken, so I've
started work on a module
based on that, but a little more to my taste (simpler, and no messing
with event handlers).
I now have something that should serve my needs quite well, but...

I have a function ask_string, which is intended to play a message file,
and read in a
DTMF string that is entered as a response. The problem is that if I key
at a reasonable
speed, the system doesn't seem to be able to handle it. With autostop
on, it gets at most
two characters before the stopping interferes with the DTMF reception,
and with autostop
off I seem to be able to get 3 characters.

My questions are:

1) has anyone else done this before?
2) is anyone else interested?
3) who understands vgetty well enough to be able to answer questions on
what it does in
certain situations?
4) how much work has been done on vgetty post-1.1.18 in this sort of
area?
5) how often is vgetty likely to be updated in future?




Cheers,



Nick
