This command causes the controller to do a software reset. A software reset re-initializes all variables back to their pre-assigned values and initializes all positions to 0. Saved settings and system flags are preserved across resets, but not saved positions. Therefore commands like HM require a power cycle instead of a reset. To re-initialize settings to default, use SS X before the reset (see documentation for the SS command; note that on Tiger SS is a card-addressed command).

Additional Notes about usage on Tiger

RESET is usually a Broadcast command but can be used as a Card-Addressed Command as well. When addressed to a specific card, it resets that card and then the Comm card (required to communicate with the reset card) without affecting other installed cards.
