I have found the solution to the problem where, when trying to add another serial port, my modifications to /usr/sys/io/sioconf.c did not seem to make it into the new KERNEL. The problem is that I have VP/ix; if VP/ix is installed, the serial driver that is actually loaded into the KERNEL is the one in vpixio.a, not the one in libio.a. The makefile provided by SCO only puts a modified sioconf.o in the standard serial driver archive. So, even though VP/ix will not support COM3 or COM4, you have to update the serial device driver in vpixio.a (by hand) in order that changes be reflected in the new KERNEL. Thanks to all of you who replied.
