Abstract
A packet data communication device has a lower-layer communication tool including at least a first lower-layer portion without an error-detection and retransmission function, and an upper-layer communication tool having both an IrTran-P function and an error-detection and retransmission function. When the first lower-layer portion is used, the upper-layer communication tool performs error-detection and retransmission of arbitrary-length packet data.
