Serial Port Problem Fedora Core 6

I am having problems using minicom to connect to a Cisco router's
console port with FC6. I am trying to run minicom on a computer which
had FC4 installed with the same hardware and minicom worked fine under
FC4. When I test my serial ports with the dmesg and setserial
commands I don't get the normal output:

root@gpblinux ~]# dmesg | grep tty
Xen virtual console successfully installed as ttyS0
[root@gpblinux ~]# setserial -g /dev/ttyS[01]
Cannot get serial info: Invalid argument
/dev/ttyS1: No such device or address

Under FC4 I get the UART info from setserial and dmesg shows the irq
etc.

I'm sure I'm running minicom correctly because it works fine uner
FC4. I have tried minicom on several different computers with FC6 and
they all have the same problem and the dmesg and setserial command
provide the same output mentioned above.

I suspect that the serial port is not being activiated by default as
was done in FC4. How would I activiate it under FC6?

Looks like you're trying to set /dev/ttyS1.
Try /dev/ttyS0.

I don't run FC, but using mknod:
mknod /dev/ttyS0 c 4 64 mknod /dev/ttyS1 c 4 65
creates the files. Afterward you may need to change permissions or
owner/group. man mknod.
