com1 is my mouse [dev/ttyS0]

com3 is my internal modem modem [dev/ttyS2]

i think both share same irq ie irq 4..

this is not causeing any prob in windows...ie both devices are working fine in win98se

but in linux my modem is not being detected at irq 4

...infact its not being detected at all...and

when lspci -vv is run it shows that a communication device is on irq12....[but it should be on irq 4 but then again..read for more info on device manager stuff below]

this might be the reason why modem is not working..

the dialer program in gnome tells that...cannot open dev/ttyS2...I/o Error

i think
[1] port adress entererd by setserial is wrong [is it 0*03e8 or 0x03e8 ..this is really confusing ..sorry]
or
[2]modem and mouse irq are same ...and that is why the modem is not working...so i`ll have to change IRQ...problem is i dont know how...and ....but then again
am not a hardware engineer.....and then
or
[3]You suggest something

and yes.. in device manager..my modem is listed twice...really ..bamboozeled by this one

once in the modems column [msp3880sp-u 56k modem] com3

and there is a colum called HSF modem..where it is listed as..MSP3880SP-U 56k modem ENUMERATOR....here it shows irq 12

and...m going crazy...and think its so easy in windows...but lifes a lot like linux....need a lot of configuring...and you are never sure its gonna work alright

aztech 56k internal modem..rockwell chipset...manufacturer..conexant


......oh and i never give up....so dont tell me to buy a new modem.....cauz even if i did ..i would still have to configure this modem...and i cant buy a new modem for atleast 6 months...and i wanna learn linux

i have the drivers ...i transferred hen to a floppy...how to install them ...

I had the same problem.

I did this. Added the following:

setserial /dev/ttyS2 irq9

to /etc/rc.d/rc.local. Then I activated the file with the source command.

Problem solved

hey man thanx for the advice ...but i didnt quite get it!!

why irq 9???

and then again how to add the stuff to /etc/rc.d.local/

and i ran a command ithink ls -l /dev /modem

this dev/modem links to /dev/cua2

shouldnt this link to /dev/ttyS2 ... beacuse cua2 is obsolet now and only for backwardcampatibilty[read this of a site]

also i u could tell me how to install the drivvers for the modem..
i have them on a floppy ...file exetension is .tar.gz


i dont know a thing..linux is just a 6 days old on my desktop man...so i know very little about it...could u please xplian in detail,,,and step by step...

i think but don't quote me but by default on most machines, irq 9 is most frequently used as what i have seen with modems. i set my modem on the same irq and added it to my rc.local as well, just so i wouldn't have to type that setserial command each time i booted into linux.
is your modem a hardware modem? like can you manually change the com and irq with jumpers on the modem?

its a software modem.. winmodem

but i have the drivers ..downloaded from aztech site

and i ran a command ithink ls -l /dev /modem

this dev/modem links to /dev/cua2

shouldnt this link to /dev/ttyS2 ... beacuse cua2 is obsolet now and only for backwardcampatibilty[read this of a site]

also i u could tell me how to install the drivvers for the modem..
i have them on a floppy ...file exetension is .tar.gz

modem is pnp..as they say..no jumpers

eeewwwwwwwww.... its a winmodem...

i don't mess with them cause they are a hassle to get working..
but to install a tar.gz file... use this command:
from there after you unzip the file.. there should be a directory where ever you did unzip called what the file name was.....
cd into the directory and there should be a install or readme file.... with instructions on how to install the drivers for that card.

also you can check out www.linmodems.org for more info on winmodems that work within linux.

thanx..i did this

but still doesnt work

i think the problem her lies because of /dev/cua2 linked to dev/modem

i want dev/modem to be linked to /dev/ttyS2

i read on a sitethat cua devices may be causing the problem

can u pls tell m ehow to link the same

Sorry, Chiragw I thought you were talking about a hardware modem, one where you can change the IRQ settings.

The default, I believe is 4, but most machines have 9 available as a spare.

What I did was manually change the jumper on the modem card itself to 9.

Linux uses the default 4 but you can trick it into using 9 with the setserial command. But like Trickykid says, if you don't want to execute that command every time you boot, you have to enter it into a script file and then activate that file.

You use an editor(as root), I used gedit, to add the proper line to rc.local(there's a place near the bottom of the file set aside for someone to add things). Next you open a terminal window, cd to the proper directory then enter the following command: source rc.local. It'll ask you do you want to overwrite <something something>. I forget the name of the file, I think it was etc.issue, anyways, you enter y for yes and you're done.

But since you don't appear to be using a hardware modem, I really don't know how to advise you further. I've only had my Linux for a couple of months and just scratched the surface.
