Abstract
A control unit controls a data processing system port to communicate with different peripheral devices. The control unit determines the type of peripheral device that is being serviced and whether the port apparatus is transmitting or receiving data, and accordingly, activates a program to load a particular count into a counter. Upon reaching a specified count, the counter activates the control unit to control the sampling time of the incoming signal and to determine the interval of time or frequency of the transmitted data information signals.
