  • a control section 116 comprises user accessible controls for allowing the user to command the microprocessor 108 to perform the selective call receiver operations well known to those skilled in the art and typically includes control switches such as an on/off control button, a function control, etc.
  • the microprocessor 108 is coupled to a non-volatile memory 122, such as an Electrically Erasable Programmable Read Only Memory (EEPROM) , and a data interface 118 for controlling and communicating with the non-volatile memory 122 and the data interface 118, in accordance with the present invention.
  • EEPROM Electrically Erasable Programmable Read Only Memory
  • the non-volatile memory 122 and the data interface 118 are also coupled to each other for providing direct communication between the non-volatile memory 122 and the data interface 118.
  • the data interface 118 is constructed and controlled in a manner that meets the standards set forth in two documents entitled "PC Card Standard,” Release 2.0, and "Socket Services Interface
  • PCMCIA Personal Computer Memory Card International Association
  • the non-volatile memory 122 is pre-programmed with a plurality of software driver programs 124, each identified by an identifier 126 that identifies an external computer with which the software driver program 124 is compatible.
  • the non-volatile memory 122 also is pre-programmed with at least one application program 128.
  • the function of the software driver programs 124 is to compensate for the differences among external computers such that the interface between each application program 128 and the external computer when loaded with a compatible software driver program 124 is a viable interface. That is, a single application program 128 will function correctly with any of the external computers for which there exists a compatible software driver program 124.

  • the radio modem 100 is inserted into a PCMCIA slot 304 of the external computer 302, as shown in FIG. 3, the radio modem 100 and the external computer 302 are electrically coupled by the PCMCIA bus 120, allowing communication to take place between the radio modem 100 and the external computer 302.
  • the function of the software driver program 124 (FIG. 1) is to present a consistent interface to the application program 128 (FIG. 1) .

  • the same statement applies to application programs that may reside in the external computer 302 itself. That is, once an application program has been developed for one type of external computer 302 that is compatible with one of the software driver programs 124 of the radio modem 100, the same application program will also function correctly with other types of external computer 302 that are compatible with one of the software driver programs 124 of the radio modem 100.
  • the software driver programs 124 (FIG. 1) are part of the radio modem 100, the software driver programs 124 can be modified at the same time that future modifications are made to the radio modem 100, e.g., to add new features to the radio modem 100, etc. Such future modifications to the software driver programs 124 will be done to maintain a consistent and invariant interface for the application program 128 (FIG. 1) internal to the radio modem 100 and for any other application programs that may have been developed for external use with the radio modem 100.
  • the maintenance of the consistent and invariant application program interface allows an increase of functionality between the application programs and the radio modem, because changing characteristics internal to the radio modem, e.g., real-time clock setting commands, message storage locations, message labels, type of microprocessor used, etc., will not affect the interface to the application programs. As a consequence, it will be possible to allow greater control of the internal features of the radio modem 100 by the application programs without the risk of massive required future modifications to the application software as a result of necessary future radio modem redesigns.
  • changing characteristics internal to the radio modem e.g., real-time clock setting commands, message storage locations, message labels, type of microprocessor used, etc.
  • the cost savings provided by the ability to create a single application program that will operate on a plurality of external computers 302 (FIG. 3) while not requiring major modification for many years makes it ⁇ feasible to develop custom-tailored application programs.
  • the updating of the application software 128 and the software driver programs 124 via over-the-air selective call messages sent to the radio modem allow control of updating to be in the hands of the selective call system provider.
