Robust XON Off*
On
This printer setting only applies to the serial port if the handshaking
protocol uses XON/XOFF pacing. When
Robust XON is set On , the printer
sends a continuous stream of XONs to the host computer to indicate that
the serial port is ready to receive more data. An XON is sent every second
as long as no data is received across the serial port in the last second, the
last XON is accepted by the host computer, and the printer is
Ready to
receive data from the serial port.
