Upgrading woody from potato.

I have lost my wvdial in new kernel-image 2-4-17 686 When i try to connect
up the following appear

--> WvDial: Internet dialer version 1.42
--> Cannot open /dev/ttyS2: Input/output error

I ran wvdialconf and the system has stopped looking at /dev/ttyS2 only looks
at ttyS0 and ttyS1

Yet in the serial.conf file the following lines are at the bottom

#
#/dev/ttyS16 set_multiport port1 0x107 mask1 0xff match1 0
#/dev/ttyS16 set_multiport port2 0x147 mask2 0xff match2 0

/dev/ttyS0 uart 16550A port 0x03f8 irq 4 baud_base 115200 spd_normal
skip_test
/dev/ttyS1 uart 16550A port 0x02f8 irq 3 baud_base 115200 spd_normal
skip_test
/dev/ttyS2 uart 16550A port 0x03e8 irq 10 baud_base 115200 spd_normal
skip_test

My modem can be found at /dev/ttyS2 using irq 10. I had no problems until I
upgraded kernel from 2.2.17 to 2.4.17. Now I cant connect up yet when I go
back to kernel 2.2.17 I can connect up using /dev/ttyS2 irq10. Can anyone
help!!!!!!!

thanks in advance
