what should be there in that putchar
for the sprintf to work ??
that is how should i need to transfer
the data to that variable ?

If it is going to be serial port
communication, i would have to
use the sbuf in the putchar routine
and check for the TI bit and i have done
it as u can c in my program. But , how is
that in sprintf ???

Sprintf in KEIL does not cause any problems.
