USR Hardware Modem listed as "Unknown/Others"

[Guest Rob Runkel]

I just finished installing Mandriva 2006 from the ISOs, and I'm having problems with the modem not being

recognized. the modem is a US Robotics Hardware modem, model 5610, v. 90 thats installed in a PCI slot....

The modem worked under RH 9, but no luck so far w/ M2006.

 

When I use the system configuration gui, I get a list of detected hardware -- everything shows up - soundcard, etc., except

for the modem. If I look under "Unknown/Other" the modem shows up, even though it is "Unknown". The entry

reads something like this:

 

US Robotics/3Com 56K FaxModem 5610

PCI Bus: 1

PCI Device: 2

Communication_class: Communication_serial

 

Any idea how to get this working in kppp or elsewhere? I've googled for an answer, and I see some folks using

the setserial command, but I hate to dive in w/o knowing exactly what to do....

 

any help appreciated - Rob

You might be worthwhile checking this site for info on the modem:

 

http://www.linmodems.org/

 

and for hardware:

check to see of Mandriva supports it.

I have used a 5610B with Mandriva 10.1 and 10.0.

 

To determine the IRQ and IO ports being used by your modem:

#cat /proc/pci

 

Then use setserial command (you may need to install the setserial rpm)

 

setserial /dev/ttyS0 irqXX port XXXX uart 16550A

 

This would set up COM1. Use ttyS1 if you want COM2.

 

You will need to add the setserial command to /etc/rc.d/rc.local file to make this permanent.

daniewicz, many thanks.....I have it working....here's the whole process, in case anyone else wants to know.

 

a) cat /proc/pci

 

using info from mandriva's hardware gui (Bus PCI #1, PCI Device #2), I looked through output from the cat cmd

and found the IRQ (=11) and I/O Port (=0xc000).

 

b) less /var/log/messages

 

using the IRQ and I/O port from 'a' above, I looked through the output from the less cmd and saw that the

modem was on ttyS4 (COM5); I also verified that uart=16550A

 

c) I installed the setserial rpm from CD #3 of Mandriva 2006 ISO

 

d) setserial /dev/ttyS4 irq 11 port 0xc000 uart 16550A

 

I issued the setserial command and tested; then added it to /etc/rc.d/rc.local

so that the change is permanent

 

e) in kppp, I made sure the modem device was set to /dev/ttyS4

 

now to get DNS working correctly.....thanks again daniewicz
