It probably depends on the USB / Serial adapter.  Some USB / serial
adapters work with some software and not with other software. Others may
work with the other software.  There may also be a problem with multiple
USB / serial adapters on a hub. The driver software may map the adapters
to different COM ports the next time you start the computer.  The
drivers I have seen have no provision for hard coding which adapter is
which COM port.  Lastly, I'm pretty sure you won't be able to have
different models or versions of USB / Serial adapaters installed at the
same time. Each requires a different driver and installing one driver
requires removing the other driver.

If you are only concerned with running one radio at a time, consider a
mechanical A-B-C-D serial switch.  They should be available for $10 or
so.  You will probably need some gender changers as most of the serial
switches I've seen use female DB-9's all around, and unfortunately, the
4 output (from switch to radios) are the ones that need to be male.

I use the A-B-C-D switch approach in my shack.
