ABSTRACT:
A method, system, apparatus, and computer program product are presented for enabling a hidden port in a computing device. A determination is made as to whether the computing device has a hidden port, which is a port that is externally inaccessible to a user of the computing device and is not dedicated for general input/output (I/O) purposes. If the computing device has a hidden port, then the computing device is configured to use the hidden port for general I/O purposes and possibly also for debugging purposes. The user may optionally specify a data value that can be used to indicate whether the user chooses for the hidden port to be enabled for general I/O purposes and/or for debugging purposes. The hidden port optionally may or may not be enabled based on whether the computing device is a legacy-free device.
