Display computer with on-screen identifiers for multiple serial ports for avoiding physical mislabelling of ports

Abstract

In a display computer with multiple serial ports, there is provided an on-screen facility for identifying each of the serial ports with a numerical identifier. A process is provided responsive to a change in the status of a connection to any serial port that displays the identifier for that serial port. The change in status takes place when connecting to the serial port. The process may be effectively used in systems having their serial ports extended through a universal serial bus. The identifiers for the serial ports may be stored in a look-up table from which the appropriate identifier may be obtained and displayed upon the connection of a peripheral device to a serial port. Among the many advantages of this on-screen serial port identification is the assurance that the user will not be confused or obstructed by any errors in the physical labelling of serial ports in the manufacture or assembly of computer hardware. Such mislabelling is often the result of unintentional cross-overs in the wiring of the multiple serial ports.
