Hi,
I have recently installed linux 9.0 after completion of installation, It has asked me that " modem hardware is detected, whether shoud REMOVE CONFIGURATION or DO NOTHING..etc.
unfortunately I selected REMOVE CONFIGURATION. due to that  I could not configure my dialup modem. I have filled all ISP related stuff like username, password,phone numer...
Can any one tell me how to make my linux to detect my modem is new hardware? or is there any way to configure modem.?.
I am not able to activate my modem, always says error message of /dev/modem not found.
waiting for help
regards
sivasankar

The device name for modem is /dev/ttyS1 or /dev/ttyS0 depending on the COM port to which your modem is connected.

well I have connected to com1 port.
How do i add my modem as a new hardware?.
because i believe, it has not detected the modem, due removal of configuration during first start(after all packages are installed and initial configuration done).
I could not able to activate my modem at all...!!!

kudzu detects and configures new and/or changed hardware on a system. When started, kudzu detects the current hardware, and checks it against a database stored in /etc/sysconfig/hwconf, if one exists. It then determines if any hardware has been added or removed from the system. If so, it gives the users the opportunity to configure any added hardware, and unconfigure any removed hardware. It then updates the database in /etc/sysconfig/hwconf.



command:

# kudzu --class MODEM

should remove modem from kudzu database

but try first look to /etc/sysconfig/hwconf

Unplug the modem
Login as root into your system. If you are in the GUI screen like KDE, run the terminal program. It is in the System Tools menu.
You will get # prompt
At the # prompt, give the following:
# ntsysv
You will see the list of services.
Check if kudzu is active. If not, make it active.
Connect the modem again
Restart your system and see if the hardware is getting detected.

For COM1: the modem is /dev/ttyS0

Please check the following file after logging in as root
# tail -100 /var/log/messages
and look for the messages having ppp in them. You will get to know the error if any when the ppp service is started.
