PURPOSE: A method for controlling a data output in an OS(Operating System) is provided to operate a function of cutting off an output from other task at the same output level as an output level setup function, thereby preventing output data from being mixed. CONSTITUTION: When power is applied(510), a board is in OS load standby state(512). A CPU decides whether an OS load is necessary(514). If so, the CPU loads an OS to an RAM from a workstation(516). The CPU executes an output level setup function(518), and accumulates application programs in the RAM(520). In a prompt state(522), if a user inputs a command(524), the board performs the corresponding command(526). If an output cut-off function is operated by other task, the board decides whether an output function is transmitted from the other task at the same output level(530). If not, the board stores output data in a queue(534). The board stores the output data(536), and outputs the stored data by the output function(538). |
