+Description:
+
+TestSerial is a simple application that may be used to test that the
+TinyOS java toolchain can communicate with a mote over the serial
+port. The java application sends packets to the serial port at 1Hz:
+the packet contains an incrementing counter. When the mote application
+receives a counter packet, it displays the bottom three bits on its
+LEDs. (This application is similar to RadioCountToLeds, except that it
+operates over the serial port.) Likewise, the mote also sends packets
+to the serial port at 1Hz. Upon reception of a packet, the java
+application prints the counter's value to standard out.
+
+Java Application Usage:
+ Linux: java TestSerial.class [-comm <packetsource>]
+ Windows: java TestSerial [-comm <packetsource>]
+
+ If not specified, the <packetsource> defaults to sf@localhost:9001 or
+ to your MOTECOM environment variable (if defined).
