ABSTRACT:
A field programming tool for a personal communications device, provides an automatic, capability to update computer programs stored in the device. The personal communications device includes an electrically programmable read only memory (EPROM), that stores the operating system programs and the applications programs to be loaded into a random access memory (RAM) for executed by a central processing unit (CPU) in the device. A reprogramming card is provided for the device, containing pre-stored new programs that are to be loaded into the EPROM of the device. A method is provided for automatically loading the new programs from the reprogramming card into the EPROM, in an accurate, foolproof manner. This is accomplished using a sequencing program stored on the reprogramming card and loaded into the RAM of the device, where it is executed. An option attach connector alerts the device that the reprogramming card is connected to the PCMCIA slot of the device. It's presence is a signal to the device to begin the automatic operation of reprogramming the EPROM with the new programs stored in the reprogramming card, using the sequencing program in the reprogramming card.
