Problem with setserial ! Somebody can help me?

[Hipsoterus]

Hi..
First, sorry for my english.. I'm brazilian..
and.. I know that it is a Forum of Nvidia Drivers and Graphics for Linux, but here
have somepeople very expert in linux and I think can help me...

I have a modem U.S. Robotics 56k .. a Pci modem.. and it don't response in linux ( Mandrake 9 )...
Yesterday I install the setserial package ( setserial-2.17-6mdk.i586.rpm ) using:

rpm -ivh setserial-2.17-6mdk.i586.rpm

worked!!
So, I enter

cat /proc/pci

and there, in the end, say:

Bus 2, device 9, function 0:
Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 2).
IRQ 11.
Master Capable. Latency=32. Min Gnt=12.Max Lat=128.
I/O at 0xdf00 [0xdf3f].
Bus 2, device 10, function 0:
Serial controller: US Robotics/3Com 56K FaxModem Model 5610 (rev 1).
IRQ 11.
I/O at 0xdff0 [0xdff7].

I see, the Esonic Audio PCI ( I don't use! ) is in the same irq of my modem..
But.. I tried use the setserial:

setserial /dev/ttyS4 port 0xdff0 irq 11 uart 16550A

and don't work... showed it:

/dev/ttyS4: No such file or directory

Somebody can help me??
What's wrong?? How can I use my modem??

Linux without internet, don't have a lot of fun..

Thanks for all!

ttyS4 is COM5. Is your modem set up on COM 5? I sort of doubt it... Try ttyS0, ttyS1, ttyS2, etc. instead. Your motherboard's serial ports are probably going to be the first few COM ports, so if you have 2 serial ports, then start at ttyS2 (0 and 1 are likely your motherboard ports).

I believe (could be wrong) that most 56K modems by USR are Winmodems, though, which sucks for us Linux users. Maybe www.linmodems.org can help? Worth a shot anyway.

Modems in linux are still a very messy problem. You should visit linmodems.org and look for information specific to your modem.

In case you haven't heard the term, a linmodems is a 'winmodem' that works with linux. A 'winmodem' is a software controller modem, meaning windows does most or nearly all of the work for it to function.

On you modem, you will find the 'chipset' name and id numbers, this will be necessary in order to find out if a certain set of drivers will *actually* work for your modem.

This is a How-To document on making linmodems work.

A lot of reading may be necessary to work it out, unfortunately there is no easy short install answer.
