You are using the original code which doubles the rate you
set with UBRR registers ("set double mode"). Try with 600bps setting in the
first two lines.

one, Im doing a project in which the
sensor mote is connected to a RS232 device. Sensor is having these
properties. Baud rate-1200
bps Stop
bit-1 Parity-none Flow
control-none I have initialized the Mote UART
by async command
result_t UART.init()
{ \\ set baud rate to
1200 outp(767>>8,
UBRR0H); outp(767&0xff,
UBRR0L);
\\ set double
mode outp((1<<U2X),UCSR0A);
\\ set 7 data bits and 1 stop
bit outp(((1 << UCSZ1) | (0
<< UCSZ0)) , UCSR0C);
outp(((1 << RXCIE) | (1
<< TXCIE) | (1 << RXEN) | (1 << TXEN))
,UCSR0B);
return SUCCESS; } Now I have got the data from the
RS232 device and broad cast it to all other motes. The base mote which is connected to
the system gets the data from the TOS Message and prints it on the
terminal Unfortunately, I couldn’t get all
the data some data is missing. Is this because there is some
mismatch in baud rate. Please help me regarding
this Hari Hara Sudhan
