icant connect to internet from opensuse .

Check if your addon card is detected, run lspci. Also look in the output of dmesg. I can’t tell you what to look for, because I don’t know in advance, but anything that suggests the PCI card was detected.

If the PCI card was detected, you may have to load a module for it.

i conect internet form windows 7 and it say the modem is connet to from COM4 i think in linux is ttyS3 but the suse say can detect modem form ttyS1…,S3

#5

No, no, walk before you try to run. First check if the PCI card was detected. If that works then see if you can load a module to drive it. Only after the module is running will you see the serial devices in /dev.

#6

ok thanks im begginer in suse but how can detect pci card and how can louad moudle . is it have any tutorial or how to ?

#7

Do the steps in post #3.

#8

Please follow key_yap’s instructions.

My post is to say the following:
How did you end up buying a serial card for this purpose? You could have bought a USB-serial dongle and used on one of those USB ports.

i find a driver for this pci card and in manual of driver say :

This installation guide describes the procedures to install and uninstall CH35X PCI to two serial ports,one serial and one parport,
two serial ports and one parport,four serial ports in Linux platform.
1-install and uninstall CH35X PCI boards

(1)-install
<1>-copy ch35x_80x86.o to /usr/sbin
<2>-Add /usr/sbin/ch35x_80x86 at the end of the /etc/rc.d/rc.local.
<3>-reboot
if you inster two serials port board
The ttyS2 and ttyS3 are ready for application.

if you inster one serial port and one parport port board
The ttyS2 and LPT1 or LPT2 ready for application.

if you inster four serials port board
The ttyS2 ttyS3 ttyS4 and ttyS5 are ready for application.

if you inster two serials port and aone parport port board
The ttyS2 ttyS3 and LPT1 or LPT2 are ready for application.

(2)-uninstall
(1)-Remove /usr/sbin/ch35x_80x86 at the end of the /etc/rc.d/rc.local.
(2)-Remove /usr/sbin/ch35x_80x86.o

but i cant find rc.local. file to insert /usr/sbin/ch35x … in file . the manual is for suse 9.3

You can put it in /etc/init.d/boot.local.

But before you do that, run the command by hand to see if it finds the hardware and then you are able to use a serial terminal program with it.

#11

which is command for testing find hardware ?

#12

Just run the program in a terminal window and see if it prints out any good messages and also if it creates some devices like /dev/ttyS0, /dev/ttyS1, etc. If the program crashes or gives an error, that’s not good.
