problem with 536ep modem

soup21 · 03-20-2005, 09:02 PM

hello friends
Again a problem with modem intel536ep in suse 9.2.

I have some experience with suse 9.1 in daily usage, And had used that modem with knoppix(debian) linux very well, but when I want to use it with suse(9.2), it didn't work as follows:
I installed its drivers from distribution from suse download site but in using kppp, it disconnected just when the modem connects and before checking username/pass with my ISP.
I also tested modem with minicom, it is amazing; when minicom begins, after sending the initialization string to modem a series of infinite line-feed characters from modem is sent to minicom and no commands can be sent to modem from keyboard.

I also installed the modem driver presented in the intell.com site(after removing previous one) but nothing changed.

But it works correctly under the knoppix(debian) with the drivers for debiadn from intel.com site on the same computer!!!

Can anyone help.
Thanks so

# Configuring a real hardware pci modem
To configure a pci modem, open an x terminal and su - to the root account:

Code:

[fancy@tinwhistle fancy]$ su -
Password: 
[root@tinwhistle root]# cat /proc/pci

Look for your modem in the returned list. Look for something similar to mine:

Code:

  Bus  2, device   2, function  0:
    Communication controller: PCI device 151f:0000 (TOPIC SEMICONDUCTOR Corp) (rev 0).
      IRQ 5.
      I/O at 0xc400 [0xc407].

With this info, I use the setserial command:

Code:

[root@tinwhistle root]# setserial /dev/ttyS2 irq 5 port 0xc400 uart 16550a

Then I test the modem with the internet connection wizard and it works. I edit /etc/rc.d/rc.local and enter the setserial command:

Code:

[root@tinwhistle root]# pico -w /etc/rc.d/rc.local

My file for an example

Code:

#!/bin/sh
# Redhat /etc/rc.d/rc.local file
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
# configure modem
setserial /dev/ttyS2 irq 5 port 0xc400 uart 16550a

Now, it remains configured after a reboot.

Hello

Thanks BUT you probably know that nowadays winmodems ( or linmodems ) (such as intel 536ep ) do NOT simulate a true COM port that can be configured with the setserial command.
They only can work with their OWN drivers.

No other solutions ???!!!!

Can anyone get me a page of intel site to report this problem to them ?

Hello again

No one has any suggestion

Any comment appresiated.

Google is your friend.

Google hits

soup21 · 04-04-2005, 07:58 AM

Hello , again
Thanks BUT i tried already all of them, The problem is in the Intel 536ep driver itself.
That driver can work well with the suse 9.1 BUT not with 9.2

Yet any comment will be appreciated.
thanks

A cheap external serial port will work with all operating systems. They work much better than win-modems.

I have a win<something> or some other kernel module driver I have to install.
# Compiling/installing kernel modules
You will need to have installed:
1. The developmental packages (compiler)
2. The kernel-source code that matches your running kernel
3. The module source or install code

Check out your system and look under the hood and see if you installed the stuff you need to do the job. Open an x terminal and type in this sequence of commands to see what kernel we are running and see if you have the kernel source installed:

Code:

[fancy@tinwhistle fancy]$ su -
Password:
[root@tinwhistle root]# uname -r
2.4.20-28.7

I am running kernel version 2.4.20-28.7. Do I have the proper source code?

Code:

[root@tinwhistle root]# cd /usr/src
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          136 Jun 12 14:53 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#

I do have the same kernel version source code installed in the directory /usr/src/linux-2.4.20-28.7 and there is a symbolic link named linux-2.4 pointing to it.

If you don't see something similiar to this (but in color), you will need to install the kernel source.

NOTE: I noticed that Red Hat didn't make the symbolic link /usr/src/linux that all of the INSTALL files that I have read mentioned that I need. I may as well make one now to save editing the files in the source code every time I need to compile anything concerning the kernel. So, I'll make that link just now:

Code:

[root@tinwhistle src]# ln -s linux-2.4.20-28.7 linux         
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          160 Jun 12 15:46 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun 12 15:46 linux -> linux-2.4.20-28.7
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#

Ah, there it is, so that's done.

Next, did I install the compiler?

Code:

[root@tinwhistle src]# gcc -v          
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
[root@tinwhistle src]#

Yes, I have a compiler installed.

If you don't have those two things installed, you have to install them first off your install CD.

If they are installed, download the source and happy compiling.

Make sure you carefully read the README and INSTALL files after extracting and before compiling/installing.

Hi,

I think there are people having it to work with suse 9.2
[edit I just tried under suze 9.2 pro this week-end, worked
nearly out of the box]
do a google for this site only http://linmodems.technion.ac.il/

There should be plenty of ideas there

Let us know if you solve your problem

Hope this helps
