ACPI Device keeps Com 1 port busy

[PoopDog]

I need to use my serial port (Com 1) and I'm unable to because a PNP
device ID = ACPI/PNP0501\1 is keeping Com 1 in use (busy).
Is there a safe way to disable it? The old software, for this device I
want to use, is looking for Com 1 ONLY and can't access it.

Thanks for your reply,

In the com port setup, you may be able to change the port number
of your hardware com port from 1 to 2 so it will be available for
other applications as com 2.
