ccs example EX_SISR.C modify problem....?

[jskil7]

rs232 communi.... 12number send -> 4 hundred number reply

Buffered data => 123 456 789 012 <--- (send data )

id=8, r=152, g=229, b=220 <---(receive data)

send char -> receive char -> change int
above problem?.....
I can't find it...... help me

You're not using the EX_SISR.C code in the correct way. You should
use the bgetc() function to get bytes from the receive buffer. Don't
try to access the buffer directly.
