Abstract

The proposed system alternates the language of a bilingual keyboard of a compatible personal computer with the help of a switch which is connected to the serial port of the computer. The switch is placed between two singals of the serial port which are not used by peripheral devices for data. One of the signals is kept at logical 1 by the software and for this purpose either the RTS or DTR signals may be used. The second signal is grounded through the resistance R1 and for this purpose one of the signals CTS, DST, DCD or RI may be used. The capacitor C1 is used to handle the debouncing of the switch, so that no more than one interrupt is caused by each pressing of the switch. Whenever an interrupt occurs, the interrupt service routine changes the translation table of the keyboard from one language to the other.
