Communication terminal device, method of processing data received by same, and computer program product for achieving the method

摘要

When a communication terminal device (10) has stopped operating because it is off-line, data received from a host (90) is stored in a receive buffer (32). A command interpreter (33) interprets the receive buffer content in the FIFO order. An action buffer (34) stores interpreted commands. A command execution controller (38) executes commands in the action buffer in FIFO order. The command interpreter (33) continues interpreting the received data even when operation of the command execution controller is stopped, and deletes interpreted data in the receive buffer to get space for new data from the host device (90).
