1) DIP Switch 1-7 (on I/F Card) = OFF
A. ESC/POS Mode
Indicates whether the host can receive data.
SPACE: Host is ready to receive data
MARK: Host is not ready to receive data
a) DTR/DSR Communications Mode
Checks that status of this signal and sends data.
(However, this excludes data transmission using <DEL><EOT>,
<GS>a)
b) XON/XOFF Communications Mode
Does not check the status of this signal.
B. STAR Mode
Not Used
2) DIP Switch 1-7 (on I/F Card) = ON
Becomes an external reset signal.
Reset is applied when there is a mark status with over 1 ms
pulse width.
