ABSTRACT:
A device for coupling a host computer to a serial communications device. A dual port register set is coupled to the CPU bus of a host computer. The dual port registers receive the control signals and data from the host computer. This information is immediately available to be read by a serial communications controller. In this invention, one channel of a two-channel serial communications controller is implemented to receive the parallel data and convert it to serial output. The parallel data is also provided directly to a microprocessor interface for use by a local microprocessor, if desired. The present invention eliminates unneeded conversion steps and reduces the amount of circuitry required to implement serial communications functions.
