7.3.3 Error Detection
A parity error, framing error, and overrun error are detected. When an error is detected,
that data is either stored in the buffer as "?" or discarded. (Depends on DIP switch selection)
The ERROR lamp is illuminated.
(1) Framing error
This error results when a space is detected in detecting the stop bit. That data is either
stored in the buffer as "?" or discarded. (Depends on DIP switch selection)
(2) Parity error
If a parity check has been specified and an error is detected at the time of parity check,
that data is either stored in the buffer as "?" or discarded. (Depends on DIP switch
selection)
(3) Overrun error
If an overrun error is detected, that data is either stored in the buffer as "?" or discarded.
(Depends on DIP switch selection)
