  • Electronic postage meter having an out of sequence checking arrangement
    Patent number: 4785417
    Abstract: An improved postage meter includes a method for checking the particular operation being carried out by the meter to determine whether it is in the appropriate sequence under the given conditions. A stored program word associated with each routine to be monitored is stored in RAM whenever the routine is operating. The word can be checked as many times as desired during the operation and if a match does not occur between the stored word and the word associated with the executing routine, appropriate error recovery can be initiated.
