ABSTRACT:
An electronic device has a physical port, and a control circuit coupled to the physical port. The control circuit is arranged to electrically sense the physical port, and operate the physical port as one of an Ethernet port and an RS-232 port based on electrically sensing the physical port. In some arrangements, the physical port operates as an Ethernet port at one time and an RS-232 port at another time. In some arrangements, the electronic device senses for Ethernet signals and RS-232 signals concurrently. In other arrangements, the electronic device senses for Ethernet signals and RS-232 signals at different times in an alternating manner.
