Basic Protocol
All data is transmitted as asynchronous serial characters, suitable for transmission and reception by a UART. The asynchronous character
is fixed at 8-N-1 (8 data bits, no parity, one stop bit). Only two baud rates are supported: 9600 baud and 19200 baud.
All data is transmitted in framed packets. The host Controller is assumed to be a user PC running a terminal emulator program or an
ASCII dumb terminal that is in charge of the process of monitor and control. The Controller is the only device that is permitted to initiate, at
will, the transmission of data. Targets are only permitted to transmit when they have been specifically instructed to do so by the Controller.
All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed
characters are considered printable.
All messages from Controller-to-Target require a response – with one exception: This will be either to return data that has been requested by the
Controller, or to acknowledge reception of an instruction to change the configuration of the Target.
