Serial card not working

[juerg]

I can't get a serial extension card (EXSYS PCI EX41092) to work. After installation according to the manual using "setserial" I get the "modem busy" answer from KPPP. What am I doing wrong? (kernel is 2.6.5 if that should matter).

Output from more /proc/pci
Bus 1, device 2, function 0:

When I try to install a modem at ttyS3 or ttyS2 with KPPP, I got the message "modem busy" and the following 3 lines in the console:
Opener: received OpenLock
Opener: received OpenDevice
Opener: received RemoveLock

ttyS0 (the built in port) is working properly. Just the two serial ports on the extension card are "dead". When I write to the port, nothing arrives there. mgetty says that the modem is busy. What can I do to get this card working?
Thank's for all help!

this page helped me to get this card to work...

I used kernel 2.6.8 (SuSE9.2).

You have to change the file:

/usr/src/linux/include/linux/pci_ids.h

like mentioned

and file:

/usr/src/linux/drivers/serial/8250_pci.c

instead of the mentioned

/usr/src/linux/drivers/char/serial.c


Hope you succeed,
