Abstract: One of a first voltage and a second voltage may be selected based on input from a basic input/output system (BIOS). One of the selected voltage and no voltage may be output to a carrier detect (CD) pin and a ring Indicator (RI) pin of a serial communication port, based on the input from the BIOS.
