Abstract
When a communications terminal has stopped operating because it is off-line, data received from a host is efficiently stored to a receive buffer so that receive buffer full states cannot easily occur. A data interpreter interprets the receive buffer content in the input order. An action buffer stores interpreted commands. A command execution controller executes commands in the action buffer in first-in first-out order. The data interpreter continues interpreting the received data even when operation of the command execution controller is stopped, and kills without storing to the action buffer any real-time commands detected by the data interpreter.
