[Fwd: Vgetty question]

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

Hi Yoann,

I see your problem :-)

But I don't share your optinion. If I am not wrong you request to
rewrite the complete vgetty code - to get something which would help you
not to reinvent the wheel.... Do you see the contradiction? If you can
use it - do so. If not...
(And please send answers regarding this paragraph not to the list, but
directly to me ;-)

Why not trying to find a compromise? I can imaging that some pipe
interface would be sufficient for your needs. Start to collect the
information you'd like to get from vgetty - and than have a look at the
possibilities. And please don't start arguing about 'good' and 'bad'
programming languages/skills. 

I am sure it's not that hard to change vgetty to look at a some port for
requests or to send status to some port - just write that bit of code
and contribute it to the vgetty project. If Marc doesn't want to spend
time on it, well, he's not paid for it, is he?

'bidirectionnal communication through the modem'
You might be talking of 'chating' using the modem mic and the modem
speaker.
OK. Easily done with vgetty, perhaps a new voice mode must be invented
;-). I am sure you can get that. But, what do you want your program to
do, once the communication is established? Perhaps it is enough to dial
and write something on the X display like 'please take your telephone
and press any key afterwards'.

If vgetty continues to listen to the line it might 'fish out' DTMF tones
and busy signals. Does your modem receive DTMF events (even in 'at#vtx'
mode?!?)?
You can test that with sending DTMF sounds while some greeting message
is beeing played. The modem definitely can't send voice data to your
program while receiving voice data from your program (full duplex voice
mode between computer and modem is NOT possible (with my 'rockwell
compatible modem')). Soundcard solutions might work using additional
hardware.

Regards, Steffen
