Abstract
A portable electronic device can receive and transmit lower-case letter codes while it displays only upper-case letters. The device stores data received from a superior model as they are in a RAM. When data display is performed, a CPU determines whether or not each of letter codes contained in the data read out from the RAM is a lower-case letter code. If a current letter code is a lower-case letter code, then the CPU selects an upper-case letter code corresponding to the lower-case letter code and then reads out a character code corresponding to the selected upper-case letter from a ROM for display of the upper-case letter on an LCD. If a current letter code is an upper-case letter code, a character code corresponding to the upper-case letter code is read out from the ROM for display of the upper-case letter. When received data are reversely transmitted to the superior model, the original data containing the lower-case letter codes are simply transmitted as they are.
