Modem command information

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

Hello list,

I've got a question.

I have a prometheus Cyberphone 14.4 external modem that I would like to use
vgetty/mgetty under Linux with. During my trials, I discovered that it
apparently has a Sierra modem chipset inside. Here's the problem. I'd like
to get documentation on how to use the voice commands with the modem so that
I can either use an already existing mgetty driver or write one for it. It
doesn't respond as an at+fclass=8 as it says that it only supports 0,2. The
problem is further compounded by the fact that Prometheus has gone out of
business and they have a skeleton web site and it appears that Sierra is out
of the modem chipset business as well and I can't find anything on their web
site either. 

So my question is does anyone have any documention on the Sierra 14.4
chipset? Or know of where I might get some? FWIW neither Sierra or
Rockwell vgetty drivers operate the modem properly.

Thanks in advance for any help I can get.
