Bit7: 0~8-bit format (8,1,N/7,1,O/7,1,E/7,2,N)
1~9-bit format (8,1,O/8,1,E/8,1,S/8,2,N(8,1,M)
Note: N/O/E/M/S mean No check(None), Odd parity check(Odd), Even
parity check(Even), 1 check(Mark), 0 check(Space)
Bit6~5: 00 No check/Mark check
01 Odd parity check
10 Even parity check
11 Space check

th
Byte: Wrong parameter, fixed as 0x00
7
th
Byte: Transmit rate, set up range 00~07; Normally, the RF transmit rate
must greater than interface speed rate when setting up, it prevents having the
wrong information.

Byte: Working frequency, calculation:
MHz*1000=KHz, and transfer to 16 Bytes.
For example: When it is at 434MHz working frequency,
434*1000=434000=0x06 9F 50 fill in 06 in the 8
Byte, fill in 50 in the 10
When it is at 432.5MHz working frequency, 432.5*1000=432500=0x06 99
