You can first try to play with the several standards settings for an RS232 port COMs :
Parity bit : None, Odd, even
Stop Bits : 1,2
This will make 6 settings to test.
I doubt you'll have to test for 7 bits data...
But, do you know what you're supposed to receive and/or send ?
It's not because it's a serial link that you're supposed to receive text.
There is often serial link on devices for testing/maintenance purpose, which send (or receive) pure binary data/information.
