I don't understand the relationship between that code, which uses a baud rate of 57600 and the thread title.
My app sends servo positions every .01 seconds (100x per second), it is packed within 3 bytes (0x00,0x00,0x00) where the first byte represents the wich of the servos it's gonna move and the other two bytes include the actual servo value.
It only needs to send data when it changes, which would likely significantly reduce the amount of data sent. You are sending three bytes, when one is sufficient. You could reduce the amount of data by 66%. The value that needs to be sent is the servo position. Perhaps you've even noticed that 0 is a valid position. Send 0, instead of 0x04, to send the servo to position 0, and get rid of 0x03.
