Hi All,

I have a problem with 6x serial port = card from=20 MonsChip built on MCS9845CV chip.

I use fedora 9 with 2.6.25-14.fc9.i586=20 kernel.

Have 7 lines configured as = follows:

[root at turtle1 ~]# /bin/setserial -avg=20 /dev/ttyS*

Port that works on IRQ 3 comes from = motherboard and=20 it works fine.

All other portsworking on IRQ10 are = from NetMos=20 card and looks to be fine but do not work.

From the PCI side it looks like = this:

[root at turtle1 ~]# /sbin/lspci = -vvvx

00:0b.0 Serial controller: NetMos = Technology PCI=20 9845 Multi-I/O Controller (rev 01) (prog-if 02=20 [16550])
        Subsystem: LSI = Logic /=20 Symbios Logic 0P6S (6 port 16550a serial=20 card)

        Interrupt: = pin A=20 routed to IRQ 10
        Region 0: = I/O=20 ports at c000 [size=3D8]
        = Region 1:=20 I/O ports at c400 = [size=3D8]
        Region=20 2: I/O ports at c800 = [size=3D8]
       =20 Region 3: I/O ports at cc00=20 [size=3D8]
        Region 4: I/O = ports at=20 d000 [size=3D8]
        Region 5: = I/O ports=20 at d400 [size=3D16]
        Kernel = driver in=20 use: serial
        Kernel = modules:=20 parport_serial
00: 10 97 45 98 43 01 80 02 01 02 00 07 08 20 00 = 00
10: 01=20 c0 00 00 01 c4 00 00 01 c8 00 00 01 cc 00 00
20: 01 d0 00 00 01 d4 00 = 00 00=20 00 00 00 00 10 06 00
30: 00 00 00 00 00 00 00 00 00 00 00 00 0a 01 00 = 00

I looked at the other posts and noticed = that=20 'Kernel driver in use: serial' in my case is 'Kernel driver in use: = parport_serial' in some other cases. I am not sure whether this is a = death end=20 or not but have no clue how to change the driver = anyway.

I can configure ports without any = issues but when I=20 try to use minicom to send/receive data it simply does not=20 work.

Could anyone comment on this/help = please?=20

Many Thanks!

Cheers

Marek
