The assignment is an open-ended design exercise to implement the Transmit part of the RS232 serial data transmission process that was formerly the main method of computer communication, both machine to machine and machine to user. It is still available in the form of the COM ports of most PCs, and can be implemented on those where the ports are absent by inserting a USB interface unit. Unlike more recent developments in serial data transmission to and from computers, like USB and FireWire, RS232 is relatively uncomplicated, and hence straightforward to implement in a hardware laboratory or simulator environment.
