Com3 to Com1

I have a com1 port that is dead (on the motherboard). I bought a PCI Serial Bus that shows up as Com3. I have a program that needs to access COM1. How do I change Com3 to show up as com1? Subquestion: if I can't change it, how do I fake out the computer into thinking that Com3 is Com1?

I found this:


but I don't know how to use it. I keep getting unrecognized command errors at a cmd prompt.

Hi DrDamnit

What you should do is disable your (faulty) Com1 port in your computer's BIOS settings, then hopefully the PCI port will 'jump into its place' and solve your problem.

The exact procedure for accessing/changing the BIOS (Setup) settings varies between computers, consult your computer/motherboard handbook. Often pressing the 'del' key as the computer comes on will work.

Cheers & good luck
