Solution

The statement that is NOT true about the UART protocol is: "The data transmission rate is equal to the baud rate".

This is because the baud rate is the rate at which information is transferred in a communication channel. In the case of a UART, it might be the bit rate (not the data rate) that is equal to the baud rate. The data rate, however, could be less than the baud rate because a single data 'unit' can be made up of multiple bits. For example, if each data unit is 8 bits long, then the data rate would be 1/8th of the baud rate.
