The protocol for mtxorbctld is a simple text based protocol and will be
explained in a modified BNF syntax.

Client to Server Communication is defined as:

STATEMENT := (<COMMANDNAME> <ARGS>)|(<COMMANDNAME>)
COMMANDNAME := cursor|out|define|hgraph|vgraph|big|gio|status
                     |opt|reset|nstart|nstop|home|back|forward
ARGS := <CURSORARG>|<OUTARG>|<DEFINEARG>|<CUSTARG>|<GIOARG>|<OPTARG>
        |<BIGARG>
CURSORARG := <XPOS> <YPOS>
OUTARG := String
BIGARG := <XPOS> <YPOS> <VALUE>
DEFINEARG := Integer <CHARDEF>
CUSTARG := <XPOS> <YPOS> <VALUE>
GIOARG := <GIOPIN> <STATUS>

Server to Client responses are defined as:

STATEMENT := (<STATUS> <ARGS>)|(<STATUS> <ERRORTEXT>)
STATUS := <GENERALCODE><SUBSYSTEMCODE><SPECIFICERROR>
GENERALCODE := 0|1|2|3|4|5|6|7|8|9
SUBSYSTEMCODE := 0|1|2|3|4|5|6|7|8|9
SPECIFICERROR := Integer
ERRORTEXT := String
ARGS := <KEYNOTARG>|<STATUSARG>
KEYNOTARG := <KEY> <KEYNOTTYPE>
KEY := Integer
KEYNOTTYPE := up|down
STATUSARG := ...
