dear
      I was using atmega 32 usart to receive data from a RS485 bus .
A master is transmitting the message to many slaves(atm32). The 
problem is: message to different slaves have different length .so 
please suggest an idea to enable the slave to receive data  of 
particular length only

The protocol you use should have an addressing system to talk to
the slaves as all the RS485 systems I know of do. This means that
only the slave which has a corresponding address to the one in the
data packet will recaive the data, all others will ignore that packet.
