PROBLEM TO BE SOLVED: To provide a communication control system that can relieve a load of a CPU of a device to be controlled in a transmission system or the like, adopting the 'Sony disk 9-pin protocol'. SOLUTION: An AV server 30 is provided with a serial communication I/F 1 having a storage means 1a for temporarily storing a prescribed number of character strings sent from a transmission means, a detection means 2 which detects whether or not the interval between characters sent from the transmission means is a time to be judged as a communication error or over, and with a reception means 3 that receives the character string via the I/F 1. The I/F 1 applies 1st interruption to the reception means 3 every time the storage means 1a stores the characters. When the detection means 2 detects that the interval is a time to be judged as the communication error or over, the detection means 2 applies 2nd interruption to the reception means 3. The reception means 3 receives characters of the character string on the basis of the 1st interruption and judges whether or not the reception of all the character string is finished, and judges the presence of a communication error on the basis of the 2nd interruption.
