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 Regards, N.- -- http://arhuaco.org
