PCMCIA modem works in Suse 7.2 but not in EE 6.10 using kppp

[Uwe Brauer]

Hello

I tried to use a pcmcia card modem, I have been using successfully in
an old Laptop running Suse 7.2.

Now here in Kubuntu 6.10 

dmesg tells me:
pccard: PCMCIA card inserted into slot 0
[17181357.752000] pcmcia: registering new device pcmcia0.0
[17181357.796000] 0.0: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

However kppp does not find a modem in ttyS0!

Is there any other tool I could use?

thanks
