property Baud : LongInt
Default: 19200
Determines the baud rate used by the port.
Generally acceptable values for Baud include 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200.
If the port is open when Baud is changed, the line parameters are updated as soon as any data existing in the output buffer has drained. Baud does not validate the assigned value before passing it on to the communications driver. The driver may reject the value, leading to an exception.
You can enter a baud rate using the Object Inspector or invoke the SelectBaudRate property editor, which provides a drop-down list box of standard baud rates.
