Abstract

A method in a communications receiver (20) for handling a selective call message comprises the steps of measuring a parameter of the selective call message (104, 116) and selecting whether to provide the selective call message to a display (118) or a communications port (106) in response to measuring the parameter of the selective call message (104, 116). The communications receiver (20) can function as either a pager or a radio frequency (RF) modem. A controller (66) determines the parameters of the message and operates the communications receiver (20) as a pager or as an RF modem in response to the parameters measured.
