ABSTRACT:
An adapter is provided to interface a full-size keyboard with a handheld computing device. The adapter couples to the serial cable of the keyboard to convert keyboard generated signals to code, such as ASCII code. The adapter has a wireless transmitter (e.g., IR or RF transmitter) to transmit the code via a wireless link to a compatible receiver in the handheld computing device. The adapter enables a user to employ a full-size keyboard to enter data into a handheld computing device having a miniaturized or limited keypad.
