(5) Baud rate : 150, 300, 600, 1,200, 2,400, 4,800, 9,600, 19,200, 38,400,
57,600, 115,200(bps)

Format (bits) (bits) (bits) (bits)
A 1 7 1 (even) 2
B171 (odd)2
C 1 7 1 (even) 1
D171 (odd)1
E18None2
F (default) 1 8 None 1
G 1 8 1 (even) 1
H181 (odd)1
I 1 8 1 (even) 2
J181 (odd)2
Selecting a data length of 7 bits allows you to transmit alphanumerical characters
and symbols but inhibits you from transmitting punctuation characters and using
2-byte codes to send dedicated characters and user pattern characters.
(8) Bit configuration
Formats A and B
Start b0 b1 b2 b3 b4 b5 b6 Parity Stop Stop
Formats C and D
Start b0 b1 b2 b3 b4 b5 b6 Parity Stop
Formats E
Start b0 b1 b2 b3 b4 b5 b6 b7 Stop Stop
Formats F
Start b0 b1 b2 b3 b4 b5 b6 b7 Stop
Formats G and H
Start b0 b1 b2 b3 b4 b5 b6 b7 Parity Stop
Formats I and J
Start b0 b1 b2 b3 b4 b5 b6 b7 Parity Stop Stop
Order of code transmission: Transmission occurs beginning with the least significant bit (b0).
(9) Error control
● Vertical parity error (detection on an individual character basis)
● Overrun error
● Framing error
