144 AMSP Modem Fax D/V/S Sound Card

144 AMSP Modem Fax D/V/S Sound Card

Post by Chri » Tue, 15 Feb 2000 04:00:00



Have just begun installing RH 6.0 Linux on my Packard Bell Pentium 75
(decided to learn Linux).  I can't get sound to work.  My sound card and
modem are one and the same, the 14.4 AMSP Voice Fax Modem with onboard
sound.  What do I need to do to implement sound?  Any help at all would be
great, evenif I have to fudge things around.

Thanks!

Chris

1. Intel 144 fax modem on an HP9000/715 w/HPUX

: I am able to call out using 'cu'.  I can connect to another modem, log in to
: BBSs and everything.  However whenever I call in to the HP, the Intel will
: answer connect and then twiddle its thumbs.  One symptom is the SD and RD
: lights never flicker no matter how hard I hit the keyboard.

This is symptomatic of a race condition between the modem and the getty.
The modem presents the word "RING" as data to the system.  If the modem is
configured to force CD, or if the getty has been configured (or is poorly
written), so that it ignores CD, it will receive the RING, and echo it back
to the modem, which at this point has not detected carrier, and so is still
in command mode.  It rejects the echoed "RING" as an invalid command, but
echoes it back to the system...........
On most modems, this causes the SD and RD lights to blink furiously, but not
on the Intel.  Try a breakout box to examine the state of the SD/RD lines.

You could program the modem to not return result codes (ATQ1).
Or, you could program the modem not to echo (ATE0)
If you change modem echo/result codes, you need to adjust your Dialers entry.

From Unixware /etc/uucp/Dialers on my system:
