The data format can be set using functions and menu options in
SelecType.

Handshaking
The printer’s serial interface can
use
DTR (Data Terminal Ready)
signal levels and XON/XOFF communication protocols either
separately or in combination. When the vacant area for data in the
input buffer drops to 128 bytes, the printer outputs an XOFF code
or sets the DTR signal level to low (MARK, indicating that it
cannot receive more data).
Once the vacant area for data in the buffer recovers to 256 bytes,
the printer outputs an XON code or sets the DTR flag to high
(SPACE), indicating that it is again ready to receive data.
Error handling
A
l
character is printed if a parity error, framing error, or over-run
error is detected.-
