MOXA Serial Port Names
Each MOXA serial port is referenced as port number in terms of programming. The
port numbers are automatically assigned, once the port numbers are decided when
configuring the ports of the board.
For example, if 8 ports are configured and the starting port number is 1, then the
mapping of serial port numbers will be as depicted in the following picture.
