I recently installed an SUSE 10.0 system on my somewhat older computer and now 
have a little problem with the serial ports. 
 
I have an server with 1 normal serial port and a multiport serial card (lspci 
output): 
00:0a.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad 16950 
UART) function 0 (prog-if 06 [16950]) 
        Subsystem: Oxford Semiconductor Ltd: Unknown device 0000 
        Flags: medium devsel, IRQ 10 
        I/O ports at c400 [size=32] 
        Memory at cfff6000 (32-bit, non-prefetchable) [size=4K] 
        I/O ports at c000 [size=32] 
        Memory at cfff5000 (32-bit, non-prefetchable) [size=4K] 
        Capabilities: <access denied> 
 
The system setup only initialized 4 serial ports: 
ttyS0 - external serial 
ttyS1 - probably nowhere connected, but existing 
ttyS2 - serial card port 1 
ttyS3 - serial card port 2 
port 3 and 4 are missing:

Previous there was an SuSE9.1 installed, which detected the serials as: 
 
device       port      irq 
ttyS0        0x3F8     4 
ttyS1        0x2F8     3 
ttyS14       0x400     10       (now ttyS2) 
ttyS15       0x408     10       (now ttyS3) 
ttyS44       0x410     10 
ttyS45       0x418     10 
 
I digged into the system, but did not find out, how the automatic device 
handling works into detail and did not find any solution. I tried setting up 
this using mknod and setserial, but it seems this is no longer possible? 
 
I can provide any additional information if this helps. 
 
Would be nice to get this fixed.
