If you are working with a PC-based platform:
The third and fourth instance of COM simply change the registry, adding
new instance of the same COM driver. Check that the I/O address and
interrupt configured for those port are correct and, if you need to
share the same interrupt (usually 3 or 4) between the same serial port,
you should enable the serial ISR (I don't know if it's enabled by
default).
If you are working with another platform:
Check that the interrupts for the 2 additional port are handled in your
OAL and translated to SYSINTR that are different from the ones used for
the other 2 ports. Check also that the I/O addresses don't overlap.
