ABSTRACT:
A method for operating a local device to permit a host computer to assert control over the local device via a communication port. A control available time window of prearranged duration is set up in the local device in response to a power on start condition. During this control available time window an Assert Control signal is received from the host computer. An Acknowledge Control signal is sent to the host computer upon receipt of the Assert Control signal during the control available time window. Then the local device responds to any control commands and data received from the host computer. Finally, the local device initiates processing of a normal local device application processes when no Assert Control signal is received during the control available time window or after the host computer has finished sending control commands and data to the local device.
