Neither DOS nor XENIX holds any information about the COM ports
in CMOS.

DOS-BIOS supports only COM1 and COM2.

Xenix isn't interested in the COM-port BIOS routines. It has special
device drivers for the ports already built into the kernel.

The kernel support for COM3 and COM4 is just commented out in the
/usr/sys/io/sioconf.c - file.
