Hi Nilesh,
Depending on what you are trying to do you may or may not be able to use this port. If your program waits till it hears some thing from the radio and then sends it to the UART, this will work ok. If your program polls the UART for data and then sends it over the radio this will also work ok as well.
The problem comes about when you want to be listening to the radio and the UART at the same time. Like say you code is trying to do something like TOSBase; The mote can not do this because it can not listen for data from both the UART and the radio at the same time.
Hope this is helpful,

Hi All,
I am trying to interface the Tmote to a PC using the 2 UART pins on
the expansion slot. We are not using the USB port as the PC board does
not has one and only has a COM port for serial communication. I wanted
to know if someone has tried this before. Also which all interfaces one
has to use to configure packets and receive data from PC? Please share.
Regards,
Nilesh
ps: I am using MAX3235 for RS232 - CMOS conversion.
