Struct BaudRateChangeRequest

#[repr(C)]
pub struct BaudRateChangeRequest { /* private fields */ }

Setting Baud Rate (Optional)

An optional feature available on selected versions of firmware is the ability to perform a “Fast Serial Download”. To support this feature, the serial port settings need to be adjusted prior to downloading packets. The serial port settings shall be reverted back to the original values after the last packet has been acknowledged by the device.

STX	LEN	CTRL	DATA0	ETX	CHK
0x02	0x06	0x5n	baud	0x03	zz

Data0	Description
0x01	Baud Rate 9600; Data Bits 8, Parity None; Stop Bit 0ne
0x02	Baud Rate 19,200; Data Bits 8, Parity None; Stop Bit 0ne
0x03	Baud Rate 38,400; Data Bits 8, Parity None; Stop Bit 0ne
0x04	Baud Rate 115,200; Data Bits 8, Parity None; Stop Bit 0ne
Other	Reserved

Warning If the device firmware does not support the fast serial download feature, the device will not respond to the baud rate change request. This means the host will be required to perform the download using the original algorithm.
