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)

7.3.4 Data Receiving Control

When the DTR signal is a space, the data from the host side can be received. When it is a mark, however,

the data cannot be received.

7.3.5 Buffering

The DTR signal is available as a control signal for data transfer to the input buffer.

• Normal print setting

Capable of buffering 100-byte data.
