Abstract
The present invention discloses an apparatus and a related method for achieving the purpose of improving the computer performance while inputting characters by using personal digital assistant (PDA) devices. The parallel port of the computer is connected with the PCMCIA (Personal Computer Memory Card International Association) card of the PDA device, and then a handshaking scheme is applied to establish a connection between the PC and the PDA device. After the connection has been successfully established, the input characters are transferred from the PDA device by parallel transformation without increasing the loading of the computer.
