摘要：Serial communication is by default meant for computer to modem communication. One fascinating idea presented in this paper is the ability to effect serial communication between two computers. We desire to maximize the serial ports such that file(s) can be transferred directly between two computers connected with a serial cable and connectors. The essence is to widen the understanding on how this kind of communication can be made possible. Our methodology configures a null modem cable in a way that the transmitting computer is deceived that it is transmitting a modem. A C program is then written to manage the transmission. Test transmission shows that file(s) can be effectively transmitted using serial communication.
