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.

(9) Error control
●
Vertical parity error (detection on an individual character basis)
●
Overrun error
●
Framing error
