Hi Prem,
As Christian pointed out, to reduce the transmission range you have to
reduce the transmission power. In Tinyos 2 with a platform with the
cc2420 (such as MicaZ and the Tmotes), you can use either a flag in the
makefile:
CFLAGS += -DCC2420_DEF_RFPOWER=1
or you can dynamically change

It sounds like you have Cygwin related issues. Did you install MoteWorks

If by no data you mean a value of zero, you are correct...
Those last 00 00 should be your two bytes of data.
