Standard Code for Information Interchange) is a character-encoding scheme based on the ordering of the
English alphabet. This is the simplest communications protocol. It transmits only ASCII characters and uses
ASCII control codes. It implies little or no error checking.
The HPR Lite commands are made up of three or more characters followed by a carriage return (Enter key).
Generally, the first three letters designate the command and the remaining letters/digits designate the
command's parameter. The commands are not case sensitive. Space needs to be inserted between the
command and its parameter. The backspace key can be used to correct an improper command. The
responses to the commands confirming the requested action or setting parameter change are sent back by
the reader.
The following is a list of the available commands.
