The problem is that 123 version 3.0 did not conform to the DOS Protected Mode
Interface (DPMI) that Windows requires DOS-extended programs to use.  123 3.0
used an older specification called VCPI (Virtual Control Program Interface).
What you should do is upgrade to 123 Version 3.1, which uses DPMI and is able
to run from enhanced mode.

Check your PIF file to see if you have the Uses COM1 (or COM2 or whatever) box
checked.  If it is, then Windows assumes the program uses the COM port.
Perhaps all the extra times Windows is asking about the COM port are due to the
fact that you may inadvertently have the Uses COM1 box checked in many of your
PIF files when it is not necessary.
