Abstract

A method and apparatus for automatically transferring control of a portable radio communication device (101) having an internal processor (108) and a first data port (118) comprise transferring (412, 414) control from the internal processor (108) to an external computer (103), the external computer (103) having a second data port (128). In the portable radio communication device (101) the internal processor (108) detects (406) a signal at the first data port (118), the signal indicating that the external computer (103) is coupled to the portable radio communication device (101) through the first and second data ports (118, 128). In response, the internal processor (108) transfers (412, 414) control of the portable radio communication device (101) from the internal processor (108) to the external computer (103).
