Knoppix and kppp

mrob · 03-19-2005, 06:26 PM

I have been trying to configure kppp on my copy of Knoppix 3.2. When all the values are added I click "connect" and the following error message is displayed:

Error-kppp
kppp can not find:
/dev/modem

How can I set the correct device?

It depends on which port your modem is on
try to change the configuration from /dev/modem to

/dev/ttyS0 #this is the window$ COM1
/dev/ttyS1 #this is the window$ COM2
/dev/ttyS2 #this is the window$ COM3

(these are the most common)

If you want to use the modem as the device "/dev/modem", you ought to make a symbolic link by this way

%ln -s /dev/modem /dev/ttyS1 #or the correct one

You should also make sure you have a supported modem and that you have the driver module for it. A lot of winmodems are now supported by the Linux kernel, but many more aren't.

emathias and masonm, thanks for the response. I'll try the link. My modem is a USR 56k Performance Pro Modem.

I set the modem to ttys2, com3. Now when I try to connect a message is displayed that:

The modem is busy

As far as I can tell nothing is using the device.

This "might" be an unsupported WinModem. Check http://www.linmodems.org/
for a comprehensive list of supported and unsupported WinModems, as well
as links to the drivers (a number of which are closed source and as such
are not and cannot be part of the main kernel).

I think that it is an internal modem. Some modems failed to get detected . You might find some help in the site said by emathias.

Does this mean that Linux doesn't support a USR PCI moden?

emathias · 03-20-2005, 07:46 PM

???? or is that USR does not support linux ???
go there and see by yourself

If a one makes things compatible with M$ it is not the fault of Linux.
