An option attach connector has a first indicator bit combination that alerts the device that a public switched telephone network connection has been made to it. The presence of the first indicator bit combination is a signal to the device that telephone, FAX, and E-mail communications applications are to be conducted over a PSTN link. The presence of the first indicator bit combination invokes the stored computer program to display images of menus, keypads, and visual presentations on the LCD display that are consistent with a basic display layout for both cellular telephone network and PSTN modes, but that include customized presentation features that are unique to the PSTN mode of communications. The presence of a second indicator bit combination different from the first indicator bit combination invokes the stored computer program to display corresponding images of menus, keypads, and visual presentations on the LCD display that are consistent with the basic display layout for both cellular telephone network and PSTN modes, but that include customized presentation features that are unique to the cellular telephone network mode of communications.

A radio telephone which communicates via cellular telephone networks and by direct connection to a PSTN. The radio telephone includes a random access memory for storing a character string comprising dialing digits defining a calling number and DTMF digits representing signalling tones for accessing information to called equipment. The character string includes a delimiting character for separating dialed digits and DTMF digits. In a dialing sequence, the cellular radio will dial numbers defined by the dial digits and send the remaining characters as DTMF tones to connected telephone.
