Some commands require parameters to be sent after the command has been accepted by the scanner. Commands and parameters are listed separately if the handshaking method requires they be sent separately.

Parameters denoted by n are two-byte parameters (ranging from 0 to 65,535 decimal), with the lower byte preceding the higher byte. Where necessary, the lower byte is denoted by L and higher byte by H.
