Title:
Modem volume not turned off by AT&FH0M0.
Status in “system-tools-backends” package in Ubuntu:
Invalid
Bug description:
When going online with ppp0 the modem can be heard dialling and
negoiating regardless of the `Modem Volume' setting in network-admin.
Changing the volume setting shows a corresponding change in the chat
file's Hayes commands but they're not having an affect although I
succesfully get online.
I think the problem is the chat file has commands after the `&F' reset
factory defaults command. It seems my modem (from Demon Internet in the
UK) prefers the `H0M0' to be on a separate AT command, or as part of the
D[TP].
Here's the default /etc/chatscripts/ppp0 which is always noisy.

Here's my edited version which is always silent.

I tried this one to see if a delay after the &F before the DT would give
time for the &F effects to settle down but it too was noisy.

One other interesting thing, chat's syslog shows that the trailing `0'
of `H0M0' is often missing from the text received from the modem.
send (ATZ^M)
send (AT&FH0M0^M)
expect (OK)
-> ATZ^MAT&FH0M^M
OK
-- got it
send (ATDT08089916001^M)
timeout set to 75 seconds
expect (CONNECT)
^M
ATDT08089916001^M^M
CONNECT
But not always, here it was echoed back but it was also still noisy so
the lack of `0' doesn't tally with the lack of `ATM0' behaviour.

send (AT&FH0M0^M)
expect (OK)
ATZ^MAT&FH0M0^M

Please split the `&F' from the following commands so they have an effect
on a wider range of modems.
