Serial Door is a program that allows to transfer files directly from one
computer to another, using a serial connection. It has been designed to work
with heterogeneous systems, both equipped with a RS-232 serial port. The
mechanism works by launching Serial Door on both computers, connected to
each other via serial port (e.g. with a null modem cable), and managing
both ends of the communication with just a few settings (essentially, the
port to be used and the transfer speed). The mechanism implemented has been
designed to be as simple as possible, so is not reserved to advanced users.
