I want the serial ports of my Digi ASYNC card to start on COM1, but the adapter will not install correctly. The native serial/COM port(s) have been disabled in the BIOS prior to the installation of the Digi ASYNC card.
At least one serial/COM port must be enabled for the ASYNC driver to install properly. Then you may disable the native port(s) in the BIOS and renumber the Digi COM ports as needed.
