Portable information terminal/method for renewing programs using PC card with utility programs on PC card displayed for selection according to control signal from controller

摘要

A portable information terminal capable of updating a program using a PC card, and a method for updating a program using the same, are provided. The portable information terminal is capable of updating a pre- stored program using a card in which a new program to be updated and a utility program for performing an updating operation are stored. The terminal includes a card unit for reading or writing the new program and the utility program stored in the card, a program storage unit for replacing the pre-stored program with the new program stored in the card and storing the new program, a memory for temporarily storing the new program and the utility program read by the card unit, and a controller for controlling the execution of the utility program stored in the memory so that the new program stored in the memory can be stored in the program storage unit. Thus, a program is correctly updated without an additional special device.
