-/**
- * The TinyOS 2.x base station that forwards packets between the UART
- * and radio.It replaces the GenericBase of TinyOS 1.0 and the
- * TOSBase of TinyOS 1.1.
- *
- * <p>On the serial link, BaseStation sends and receives simple active
- * messages (not particular radio packets): on the radio link, it
- * sends radio active messages, whose format depends on the network
- * stack being used. BaseStation will copy its compiled-in group ID to
- * messages moving from the serial link to the radio, and will filter
- * out incoming radio messages that do not contain that group ID.</p>
- *
- * <p>BaseStation includes queues in both directions, with a guarantee
- * that once a message enters a queue, it will eventually leave on the
- * other interface. The queues allow the BaseStation to handle load
- * spikes.</p>
- *
- * <p>BaseStation acknowledges a message arriving over the serial link
- * only if that message was successfully enqueued for delivery to the
- * radio link.</p>
- *
- * <p>The LEDS are programmed to toggle as follows:</p>
- * <ul>
- * <li><b>RED Toggle:</b>: Message bridged from serial to radio</li>
- * <li><b>GREEN Toggle:</b> Message bridged from radio to serial</li>
- * <li><b>YELLOW/BLUE Toggle:</b> Dropped message due to queue overflow in either direction</li>
- * </ul>

-Description:
-
-BaseStation is an application that acts as a simple Active Message
-bridge between the serial and radio links. It replaces the GenericBase
-of TinyOS 1.0 and the TOSBase of TinyOS 1.1. This base station
-is for CC2420-based platforms (e.g., micaz, telos).
-
-On the serial link, BaseStation sends and receives simple active
-messages (not particular radio packets): on the radio link, it sends
-radio active messages, whose format depends on the network stack being
-used. BaseStation will copy its compiled-in group ID to messages
-moving from the serial link to the radio, and will filter out incoming
-radio messages that do not contain that group ID.
-
-BaseStation includes queues in both directions, with a guarantee that
-once a message enters a queue, it will eventually leave on the other
-interface. The queues allow the BaseStation to handle load spikes more
-gracefully.
-
-BaseStation acknowledges a message arriving over the serial link only if
-that message was successfully enqueued for delivery to the radio link.
-
-The LEDS are programmed to toggle as follows:
-
-RED Toggle - Message bridged from serial to radio
-GREEN Toggle - Message bridged from radio to serial
-YELLOW/BLUE Toggle - Dropped message due to queue overflow
- in either direction
-
-Tools:
-
-tools/java/net/tinyos/sf/SerialForwarder.
-
-See doc/serialcomm/index.html for more information using these tools.
