It sounds like you are having more basic problems than just the ira-2 
device configuration. The /dev/ttyS0 needs to be adjusted for your 
specific setup. The ttySx is dependent on how your system is setup. If a 
'cat /dev/ttyS0' is attempted on a working system the command is just a 
blank line waiting. If the 'cat' is done on an unconnected port (such as 
/dev/ttyS1 on my system) it will display the same as you have shown above.

Here is what is listed for serial ports on my system:

ll /dev/ttyS?
crw-rw---- 1 root uucp 4, 64 2007-11-07 11:58 /dev/ttyS0
crw-rw---- 1 root uucp 4, 65 2007-11-07 11:58 /dev/ttyS1
crw-rw---- 1 root uucp 4, 66 2007-11-07 11:58 /dev/ttyS2
crw-rw---- 1 root uucp 4, 67 2007-11-07 11:58 /dev/ttyS3

You can check your serial ports with stty -F /dev/ttySx. That will 
provide the parameters of the specific port. A port with a working ira-2 
on my system shows:

[root at shuttle1 ~]# stty -F /dev/ttyS0
speed 9600 baud; line = 0;
min = 1; time = 1;
ignbrk -brkint -icrnl -imaxbel
-opost
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke

The unconnected port displays:

[root at shuttle1 ~]# stty -F /dev/ttyS1
stty: /dev/ttyS1: Input/output error.

You need resolve which port you have actually connected the ira-2 device 
first. Then make those adjustments in the configuration.
