I have some suggestions.  Try to run a loopback on the serial port(s).  
Also maybe try to use the other serial port on the system if you think 
the system is the problem.  Also check your CMOS setup to verify the 
ports are using standard settings for COM1 (3F8 IRQ4) and COM2 (2F8 
IRQ3).

Good Luck, Greg
