i have been wondering what is baud rate. could someone explain?
thanks,

Baud Rate is how fast the communication is between boards or flow rate of data.
At slow speeds, only one bit of information (signaling element) is encoded in each electrical change. The baud, therefore, indicates the number of bits per second that are transmitted. E.g, 300 baud means that 300 bits are transmitted each second.
At higher speeds, it is possible to encode more than one bit in each electrical change. 4,800 baud may allow 9,600 bits to be sent each second. At high data transfer speeds, therefore, data transmission rates are usually expressed in bits per second (bps) rather than baud.
Google is always a good place to find info.
Agree, Google is the Oracle to all questions. When someone at my work tries to feed me a bunch of bull, I always turn to Google to get the real facts. We have a know-it-all at my work, and it turns out, he’s only 50% right (average) just like anyone else. 
Anyway baud is the speed of communication and its important to robots that the two devices communicating have the same baud rate or there would be no communication.
