mServer provides various kinds of interfaces that the user end
program can connect to, for example, TCP port, physical serial port,
and virtual serial port. The mostly used interface is virtual serial port.
In mServer, map MD-309 to virtual serial port, then open this virtual
serial port with COM or other serial port software to communicate with
the serial port devices that connect with MD-309.
