serial modem connection

[mishcopal]

Over the last 3 weeks I have spent every night trying to make Fedora 5 recognize my D-Link serial port connected modem.

I have a Compaq p4 which I want to install Fedora 5 on. When I install Red Hat 9 it will recognize the modem and connect to my ISP without problems. Fedora 4 will recognize the modem but is unable to connect to the ISP. I have tried 2 different downloads of Fedora 5 from the Internet, 1 copy from a computer magazine, and 1 commercially purchased software package with the same frustrating result.

I have also tried Solaris 10 which said there was a problem with one installation disk, which prompted me to change the CD drive, and try Fedora again, but the end result is the same.

I can get as far as kppp querying the modem via the serial port before it ‘locks’ up. It does not detect the modem using /dev/modem.

You have a good program if you could make it work

when you try /dev/modem, is there actually a /dev/modem device file?
Usually /dev/modem is a link pointing to one of the ttyS0,1,2,3 files

Try setting KPPP to use /dev/ttyS0 as the modem device or /dev/ttyS1
(it depends on what serial port you used) instead of /dev/modem
since it's possible you don't even have /dev/modem

thank you very much for your reply - have tried /dev/modem and cannot find any device.

/dev/ttys0 gives 'no modem found'

/dev/ttys1 gives 'connecting to modem' before kppp 'freezes' and has to be forceably shut down and a 'reboot' is required because it leaves a file on the system that even though i delete it, kppp will not run again

mishcopal: are you booting up the PC and then later powering up the modem or
is the modem powered up and all the cabling is hooked up to the PC at the time
the PC is booted up? udev is what makes the device files under /dev in FC5,
I just wonder if maybe udev doesn't make the /dev/ttyS# files if the
modem isn't alive at boot time. But that's a hint I read about on a ubuntu
forum so I'm not sure if that relates to fedora

I guess that's unlikely because my PC doesn't even have serial ports
to plug a modem into and my /dev directory has the ttyS{0,1,2,3} files

have you actually used "ls" to confirm the serial devices are there under
/dev before you try kppp? Expect to see:

ls -l /dev/ttyS?
crw-rw---- 1 root uucp 4, 64 Jun  9 20:07 /dev/ttyS0
crw-rw---- 1 root uucp 4, 65 Jun  9 20:07 /dev/ttyS1
crw-rw---- 1 root uucp 4, 66 Jun  9 20:07 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 Jun  9 20:07 /dev/ttyS3

The thing about needing a reboot for kppp to start again might
be related to secondary processes kppp starts: pppd is the
big one. pppd makes a lock file(s) in /var/run/ppp. If kppp has
a problem, make sure /var/run/ppp/*.pid files are gone
and the pppd process itself is killed off. When you reboot,
there's a init script that cleans up /var/run and /var/lock
areas of these lock files and the reboot cleans out hung
processes for sure too.
I can't actually try any of this right now because my PC is
legacy free and doesn't even have a serial port (I have
a nice external modem though from earlier pc's)

Thank you very much your efforts. I spent another 3 hours on it and have it now working (?)

I have disabled the firewall and all internet security and now i can find the modem on /dev/ttyS0

It is a little s l o w but will now dial out and connect to my ISP and i can download pages / surf etc

now if i can only get the 'update software' to work everything would be as it should be

i would like to thank everybody very much for their help
cheers
