Can't get modem recognized

[J Y <jhy@x-mail.net>]

Although I am able to use the modem in Mandrake & SuSE I can't get 
Debian 3.0 to see the modem. It (the modem ) is located at /dev/ttyS4. I
used ppp config to set up and the info is in there correctly. KPPP
doesn't work and when I use pon at a terminal window I get a message
that says 'unrecognized option /dev/ttyS4'. Why can't I set this up in
debian? Do I have to actually move the modem from the pci slot it's in?
  Thanks
