PURPOSE:To perform inspection and maintenance adequately in accordance with whether the amount of managing information is excessive or not by printing out stored data automatically each time the amount of the data exceeds a prescribed value and printing out information on an overflow when the overflow occurs. CONSTITUTION:Communication control information during transmission and reception is stored in an RAM2. Then, a CPU compares the communication control information in the RAM2, etc., with set storage capacity; when it is greater than the prescribed value, an overflow flag is stored in an RAM1 and when not, the information is stored in the RAM2 without setting the flag. When the amount of information in the RAM2 reaches a prescribed value, it is printed out and if the RAM2 has an overflow, overflow information is printed out before and behind the managing information. |
