Serial Port Commands & Status Byte
The commands structure for communication is a single character terminated with a carriage return. When
a command is issued, the system echoes back its current status in the form of a status byte, terminated
by a
<CR>, e.g.
x00<CR>… xFF<CR>, or echoes back a string, also called
Status Byte
, like “
Part
Number:
p <CR>
”, indicating the command typed. The status byte is reported over the serial port as a
combined 8 bit value of two ASCII format bytes, followed by the a carriage return (
<CR>)
. If an unknown
command is issued, the system echoes back “Unknown Command”.
The table below lists typical
serial port commands.
