Specify the rate at which bits are transmitted
BaudRate as bits per second.
The transferred bits include the start bit, the data bits, the parity
bit (if used), and the stop bits. However, only the data bits are
The baud rate is the rate at which information is transferred
in a communication channel. In the serial port context, “9600
baud” means that the serial port is capable of transferring
a maximum of 9600 bits per second. If the information unit is one
baud (one bit), the bit rate and the baud rate are identical. If one
baud is given as 10 bits, (for example, eight data bits plus two framing
bits), the bit rate is still 9600 but the baud rate is 9600/10, or
960. You always configure
BaudRate as bits per
second. Therefore, in the previous example, set
Both the computer and the peripheral device must be configured to the same baud rate before you can successfully read or write data.
Standard baud rates include 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 128000 and 256000 bits per second. To display the supported baud rates for the serial ports on your platform, see Finding Serial Port Information for Your Platform.
