i am using http://robokits.co.in/shop/index.php?main_page=product_info&cPath=2&products_id=368 this motor in my project .
when i am writing data to motor using arduino via tx and rx .. it is responding to data character like "R1212" .. but while i am trying to read the value from motor .. i am not able to get anything ..
please help me .. i am stuck in my project work

void setup()
Serial.println("Y"); // to reset the values of servo motor
Serial.println("R1212"); // go to this relative angle .. ( and it worked )

// here is the problem while reading from motor .

Serial.println("R"); // comman byte to be read

int c = Serial.read();

void loop()
