To change baud rate of a device, follow these steps. eg: To Start communication with a baud rate of 1200.

1. Send data command for changing the baud rate to 1200.
2. Receive the acknowledgement from the device.
3. If the ACK is proper, set the Port.BaudRate=1200.

Next you want to change the baud rate to 4800, then follow these steps

1. Send data command for changing the baud rate to 4800.
2. Receive the acknowledgement from the device.
3. If the ACK is proper, set the Port.BaudRate=4800.

NOTE: Change the Port.BaudRate after receving the ACK from the controller device. The communciation will be started with the previously set BaudRate.
