Re: pci faxmodem device file


If you're using a new kernel, why not give devfs a go?  I've been using devfs
for a while now, and it's never given me any problems.  Whenever I get a
driver installed, most of the time the proper device file appears in that
directory.  However make sure you have devfsd installed first!  I've been
using it for a while, and still don't know how to use the mknod command!

Hope that helps,
