Hi.
Let's try this:
gaira:/dev# ls -lha ttyS*
crw-rw---- 1 root dialout 4, 64 2008-03-24 04:15 ttyS0
crw-rw---- 1 root dialout 4, 65 2008-03-24 04:15 ttyS1
crw-rw---- 1 root dialout 4, 66 2008-03-24 04:15 ttyS2
crw-rw---- 1 root dialout 4, 67 2008-03-24 04:15 ttyS3
gaira:/dev# mknod /dev/ttyS4 c 4 68
Try to open /dev/ttyS4 to check if the device is there. If not,
perhaps you have a driver issue. You might want to check that
the devices show up in the boot messages.
# dmesg | grep serial
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
