You could change the binary.  Load the program with debug and search for
all occurrances of the IN and OUT instructions.  Change the ones that
operate on the COM1 addresses (3f8?) to operate on the COM2 addresses.
The only other thing I can think of that would need to be done is to
change where the interrupt vector gets loaded.
