Hello ,
I was wondering if someone can help me with the following problem,

I would like to install two identical Agere PCI softModems at same machine,

Is it possible the 2 modems share the same driver?

My intention is to connect both modems to PABX and each one will use different analog lines.
I intend to dials from the first and the second answer the call.

I succesfully install for one PCI modem using agrsm driver and Slax distro like below:

# make
# make install
# modprobe agrmodem
# modprobe agrserial

# ln -s /dev/ttyAGS3 /dev/ttySAGR
# ln -s /dev/ttyAGS3 /dev/modem

But When I connect the second modem , both stop working.


The two Modems are using different IRQ's(below) but when I'm try to connect with ATZ command , it blocks and did not return ever.


For candidate card in slot 01:04.0, firmware information and bootup diagnostics are:
PCI slot PCI ID SubsystemID Name
---------- --------- --------- --------------
01:04.0 11c1:0620 11c1:0620 Communication controller: Agere Systems Unknown device 0620

Modem interrupt assignment and sharing:
--- Bootup diagnostics for card in PCI slot 01:04.0 ----
ACPI: PCI Interrupt 0000:01:04.0[A] -> Link [LNKA] -> GSI 19 (level, low) -> IRQ 20

For candidate card in slot 01:06.0, firmware information and bootup diagnostics are:
PCI slot PCI ID SubsystemID Name
---------- --------- --------- --------------
01:06.0 11c1:0620 11c1:0620 Communication controller: Agere Systems Unknown device 0620

When I take one modem off , the other works propely,

I appreciate any tip,

thanks in advance

You cannot install 2 identical pci modems in same machine.

You can install modems with different chipsets - like 1 Agere Softmodem and 1 Conexant, etc.

Aloha! Richard.
