Re: Modem problems after kernel upgrade

["J.A.Serralheiro" <mrserra@ci.uc.pt>]

well
probably you have 3 serial ports. two on board and one for your modem.
one way to find wich ports are detect is listing /proc/ioports

3f8 states as ttyS0
2f8           ttyS1
3e8           ttyS2
238           ttyS3
that is, if you stick with the normal settings in /etc/serial.conf

You can assign any I/O port to any ttySx. 
Because you board is pci, isa pnp will not interfere.

Chek /proc/pci and see what io address your modem is using.  If its pci it
will be listed. if not listed, its not detected.
then,  edit /etc/serial.conf accordingly. Even if on start up the module
serial.o assigns your modem to ttyS4, you can override this.
see the setserial man pages for more details
