Start-Stop Bits

Data Format:
Start Bit: 1
Data Bits: 7 or 8
Parity: odd, even or no parity
Stop Bit: 1 for reception
1 for transmission
If the host serial interface is configured for 7 Bit data with no parity, data from host
computer must contain two stop bits.

Handshaking Protocols:
X-ON/X-OFF: (DC1/DC3) In this protocol, the printer will respond with the
DC3 (X-OFF) character when:
Print buffer is nearly full.
Paper out condition exists.
Carriage jam condition detected.
Printer is off line.
When the printer is ready for more data, it will transmit the DC1 (X-ON) character.
ETX/ACK: The host will include the ETX character at the end of a string of
data. When the printer detects the ETX character, it transmits an
ACK character to the host, indicating it is ready for more data.
ENQ/ACK: The host will include the ENQ character at the end of a string of
data. When the printer detects the ENQ character, it transmits an
ACK character to the host, indicating it is ready for more data.
XON + ETX: Enables XON/XOFF and ETX/ACK.
XON + ENQ: Enables XON/XOFF and ENQ/ACK.
Serial port configuration can only be selected through the front panel. Only one
handshaking protocol can be selected at a time. The DTR protocol can be selected
with any handshaking protocol. If the user selects modem control, the printer will
only receive and transmit data if RTS, CTS and DSR are honored and provided by the
host.
X-ON CTRL: Only when `Robust' X-ON CTRL is selected, DC1 will be
transmitted every 4 seconds while the printer is idle and ready
to accept data. Also, if no data is being transmitted and the
printer is printing, a DC1 will be transmitted every 256 bytes as
the FIFO goes empty.
