<p><P>PROBLEM TO BE SOLVED: To provide a control method of communication apparatus for easily controlling a processing speed by arranging buffers temporarily storing produced commands in a multi-stage and capable of suppressing a fault due to overflow, and to provide the communication apparatus and a program. <P>SOLUTION: The control method of the communication apparatus comprises a means for monitoring overflow of the buffers configured in multi-stages, a means for informing of occurrence of the overflow of each buffer, and a means for informing of canceled overflow. For example, on the occurrence of an incoming call, a CPU monitors the overflow of each buffer, sets a flag denoting occurrence of the overflow to each buffer wherein the overflow takes place, and stacks an instruction code of the arrival of the call to a buffer of the next stage. When the buffer of the final stage overflows, the instruction code is discarded. When the overflow is released and a free capacity is provided to the overflowed buffer and the buffer of the next stage is idle thereafter, the flag denoting the occurrence of the overflow is reset. The occurrence of the overflow is notified by using the flags. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
