1) DIP SW3-7 = OFF
a) DTR/DSR mode
Indicates whether the host can receive data.
(This excludes data transmission that uses <DLE> <EOT> and <GS a> commands.)
IN
SPACE: The host can receive data.
MARK: The host cannot receive data.
b) X-ON/X-OFF mode
Status of this signal is not checked.
2) DIP SW3-7 = ON
