1.Square brackets “[ ]” are part of the command.
2.Use uppercase letters for all commands.
The cards in a MultiTasker™ system are capable of performing various functions, as well as providing feedback to the user or control system. Commands instruct a card to perform specific actions or request information about the status of the card. Some commands do both simultaneously.
A command that instructs the card to simply perform an action will generate feedback of “[ ]”. The open bracket immediately followed by a close bracket indicates the card received a valid
command. If the command requested information from the card, the feedback generated by the card is the acknowledgement of having received a valid command. Invalid commands generate feedback of “[ERR001]”.
After processing a command, an “OK” or [ERR001] will be returned as feedback if ‘F’ is included at the end of a command string.
Commands ending in ‘S’ will be saved into memory. Commands not ending in ‘S’ will still be executed, but will not be restored when the system is reset or powered off, then on.
