Commands are sent as <PROGRAM MESSAGES> by the controller. A <PROGRAM MESSAGE> consists
of zero or more
<PROGRAM MESSAGE UNITS> each separated by a <PROGRAM MESSAGE UNIT
SEPARATOR> which is the semi-colon character ‘;’ (3BH).
A
<PROGRAM MESSAGE UNIT> is any of the commands in the REMOTE COMMANDS section.
<PROGRAM MESSAGES> are separated by a <PROGRAM MESSAGE TERMINATOR> which is the new

<RESPONSE MESSAGES>. A
<RESPONSE MESSAGE> consists of one <RESPONSE MESSAGE UNIT> followed by a <RESPONSE
MESSAGE TERMINATOR>
, which is the carriage return character followed by the new line character
(0DH 0AH).
Each query produces a specific
<RESPONSE MESSAGE> which is listed along with the command in
the REMOTE COMMANDS section.
<WHITE SPACE> is ignored except in command identifiers. e.g. `∗C LS' is not equivalent to `∗CLS'.
<WHITE SPACE> is defined as character codes 00H to 20H inclusive with the exception of the
codes specified as ARC interface commands.
The high bit of all characters is ignored. The commands are case insensitive.
