I have installed Fedora Core 7 on my machine.
I am trying to connect to the COM1 port of an appliance to the Serial
port. (ttyS0)

I am using minicom to view the Serial port output.

On using serialport command, I am getting the error "Cannot get serial
info: Invalid argument" for ttyS0

[root@localhost ~]# setserial -g /dev/ttyS[0123]
Cannot get serial info: Invalid argument
/dev/ttyS1: No such device or address
/dev/ttyS2: No such device or address
/dev/ttyS3: No such device or address

I am unable to diagnose how may I enable the serial port output.
A quick help would really be appreciated..
