modem always busy on Mandrake 10.0

ditch* · 07-31-2004, 04:35 AM

Hey!

I've been trying to establish a dial-up connection (in vain) on Mandrake Linux 10.0.

I have KPPP as my internet dialer.

When I try to "Connect" or when I "Query Modem", the messages I get are:

"Finding Modem"

then

"Modem Busy"

I've had a suspicion that "Modem Busy" means that the computer is working on establishing a connection, but this doesn't seem to be the case, as I've left it for long periods of time without any results.

What are the possible causes of this?

Thanks a lot!

Greg

PS: I have a 56K Generic modem.

Please post the modem part of the output of the command:

# 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.

try using the modem as root if you can access it but not as normal user is a problem of permissions if this is the problem here are some tips to configure properly http://www.linuxquestions.org/questi...ght=modem+root

Is this a hardware modem, or software driven (requires drivers)?
Brand name / Model number?
Checked in HCL?

Thanks for the help!

This is what I am getting

[grisha@localhost grisha]$ su –
[root@localhost root]# cat /proc/pci

Bus 0, device 9, function 0:
Communication controller: Conexant HSF 56k Data/Fax Modem (rev 1).
IRQ 11.
Master Capable. Latency=64
Non-prefetchable 32 bit memory at 0xf4000000 [0xf400ffff].
I/O at 0x1438 [0x143f].

[root@localhost root]# setserial /dev/ttyS2 irq 11 port 0x1438 uart 16550a
- bash: setserial: command not found

Apart from the problem with the “setserial” command, I am also unsure if I was meant to copy the “uart 16550a” part from you or somehow calculate my own ‘uart’ value

( - I am as new to scripting/programming/coding/Linux as they come!

)

thanks for the help anyway. In the meantime I'll be checking out the links posted

You have a winmodem. File 13 is the best place to put it and get a cheap external serial port modem. I picked mine up for $14.50 and even Windows works better with it.

Linmodems.org
Conexant/Rockwell modem HOWTO

I think they provide a crippleware driver that will let it work slow, but they want more money for the Linux driver.

Thanks for the advice!
