<Calculation example 1>
1)Baudrate = 9600 bps, number of data char-
acters = 12, stop bit length = 2 bits, data
length = 8 bits, parity check = yes, CR, LF
instructions = yes

×12×12 = 0.015s (15.0ms)
9600
2)Same conditions as above with the excep-
tion of baudrate = 19200 bps

×12×12 = 0.0075s (7.5ms)
19200
3)Same conditions as above with the excep-
tion of baudrate = 300 bps
