All commands can be issued either in uppercase or lowercase. In the command examples, the keyboard input by the user is in bold type.
The notation <cr> refers to pressing the carriage return key (the Enter key) on your computer keyboard. Enter a <cr> to clear the command buffer before starting to enter commands.
Note that the term quantity in the serial interface corresponds to measurement parameter.
