hsfmodem picks up line but does not dial

Hi,

I'm trying to use hsfmodem on a Feisty box. Hardware as follows:

CLASS="Class 0780: 127a:2014"
NAME="Communication controller: Rockwell International HSF 56k
Data/Fax/Voice Modem "
SUBSYS=122d:4055
SUBNAME=" Aztech System Ltd MSP3880-W"
SUBven=122d
Test="./scanModem test 127a:2014 122d:4055"
IDENT=hsfmodem

I downloaded and installed
hsfmodem_7.60.00.09full_k2.6.20_15_generic_ubuntu_i386.deb - no problems
so far.

The modem is connected to the internal analog line of a AVM Fritz.Box
Fon 7050. External line is ISDN so I can't try without the Fritz.Box.

Then I tried with 'cu -l /dev/modem' the follwing AT command sequence:

$ cu -l /dev/modem
Connected.
ATZ
OK
ATDT1234567
<modem picks up the line, I can hear the dialtone...>
<after about a minute the PBX switches to busy sign>
NO CARRIER
AT &F X1
OK
ATDT1234567
<same as above>
NO CARRIER

During this, the driver did not receive any interrupt, according
to /proc/interrupts:

$ cat /proc/interrupts 
           CPU0       
[...]
  0:         40   IO-APIC-fasteoi   hsfpcibasic2

BUT: If I try to call the modem by phone, there are interrupts
in /proc/interrupts:

$ cu -l /dev/modem
Connected.
ATZ
OK

RING
ATA
<picks up the line>

$ cat /proc/interrupts 
           CPU0       
[...]
 20:         40   IO-APIC-fasteoi   hsfpcibasic2

So I don't think it's an interrupt problem, but I also tried to boot
with pci=routeirq, acpi=off and noapic, all with no success.

Finally, for your information I added the output of `sudo hsfconfig -d`
(/tmp/hsfdiag.txt).


Thanks in advance!
