cannot open /dev/modem: device or resource busy


wvdial ppp0

cannot open /dev/modem : device or resource busy

I can use this modem in Windows. I had FC5 installed and I recieved this
error. I though I'd try FC4 and still this error. I know this is a hardware modem and has worked with linux in the past. Can someone please point me in the right direction. Thanks.

/dev/modem is a symbolic link to some other device. Use this command to check that /dev/modem is actually linking to the device your modem is on:

ls -l /dev/modem

Another possible problem area is /etc/wvdial.conf. Could you post your /etc/wvdial.conf with your user name and password xxxxxx out.

just a question is there some reason like hardware ( like VERY old hardware) keeping you on the dead and unsupported fedora 5 .5 hit " End of Life " on May 31, 2007. Fedora 10 is about to be released .

What kind of modem is it 56k dial up, dsl,or what .Some "built in" win modems use MS windows code to run them . and will require "ndiswrapper" to use the win code .But there are NO rpm's or working repo's for fedora 5 so you will need to build ndiswrapper from the source code and install ( by hand some rpm's and build others) all of the dependencies for the compiler .

The modem is dial up modem. US Robotics 56k, hardware modem.

One other note. I looked in the dev directory and there is no listing for modem.

ls -l /dev/modem
file does not exist



How can I find the address of the modem. and then link it to /dev/modem

Hi,

By chance is this modem a external modem hung on the serial post?

No it's an internal hardware usr robotics modem

I know it works because the system is dual booted with windows. It has worked with linux in the past.


wvdial.conf

[Modem0]
Modem = /dev/modem
Baud = 460800
SetVolume = 0
Dial Command = ATDP
Init1 = ATZ
Init3 = mTM0
FlowControl = NOFLOW

[Dialer Freenet]
Username=
Password=
Phone=
Stupid Mode =1
Init1 = ATZ
Init2 = ATQ0 V1 E1 SO=0 &C1 &D2 + FCLASS = 0
Inherits = Modem0

You do not have a dialer named ppp0 in wvdial.conf so therefore the command

wvdial ppp0

will not work. You do have a dialer called Freenet so try the command:

wvdial Freenet

You have set the baud rate to 460800. No dial-out modem will run that fast.

Thanks to all that replied. I have the modem working now. I'm using Fedora Core 4 because I can't download due to the slow speed. I will upgrade and buy a newer verion of Redhat Fedora on Ebay.

have a look here
http://fedoraproject.org/wiki/Distri.../OnlineVendors
also it is not Red Hat fedora
Red Hat 5.2 is a commercial ( for cash$$$) distro
fedora 9, and soon 10 are not commercial
also when you buy a new computer some can have Linux preinstalled
like Dell with Ubuntu
