Re: modem works in sarge but not etch or lenny

If this is the wrong list, please tell me where to repost it.

I have a V1456VQH-X pnp ISA card that I only use for sending and receiving
faxes.  It worked in Sarge but I have not been able to get it to work in my
Lenny/Sid box.
I reinstalled sarge on a different partition and the modem still works so it
is not a hardware issue.  I believe it is a kernel issue since it works with
kernel2.4 and not with kernel 2.6.  Although it works in 2.4 (sarge) I have
not been able to find any log messages or dmesg output to tell me exactly
what the kernel is doing iwth it.  All I know is that minicom with
/dev/ttyS1 returns OK when I type AT.

I also went to an old partition with etch i(2.6.2.6.18-3-k7 #1 SMP Mon Dec 4
17:23:11 UTC 2006 i686 GNU/Linux) and it also doesn't seem to work.

dmsg returns the following:

isapnp: Scanning for PnP cards...
isapnp: Card '56K PnP DATA FAX VOICE Modem'
isapnp: 1 Plug & Play card detected total


So it does seem like the kernel finds it.  When I go to
/sys/devices/pnp1/01:01/name I find "56K PnP DATA FAX VOICE Modem"
and the file /sys/devices/pnp1/01:01/01:01.00/resources has "state =
disabled"

After "echo AUTO > resources"  the file resources contains:
state = disabled
io 0x2e8-0x2ef
irq 5

When I try running scanModem from linuxant it tells me that I need some
proprietary driver from them but, as I said, the card worked in sarge.  I
don't know whether there was a decision to stop supporting some devices or
this is a bug or I am just not configuring things right.  (If it is a
configuration issue that would also indicate a documentation bug.)  I would
like to post a bug but am not sure to which package it would go. I guess to
the linux-image2.6 package.

Any guidance would be appreciated.

Thanks,

First, see if minicom can take the modem off-hook and on-hook:

ATH1
ATH

The modem should say OK for each of those, and you might hear the modem as it changes states. Try to identify the modem:

ATI
ATI1
ATI2
ATI3

This helps ensure that you're talking to the device that you expect to control eventually. Then try to dial your ISP like so:

ATDT555-1234

You might hear the modem dialing. Since you probably don't talk PPP, you can just hang up before it makes a connection by hitting ENTER or doing the "+++ATH" thing.
