Online/Offline will reflect only the condition indicated and does not reflect a buffer full condition. Busy/Not Busy will cause DTR to indicate both the online/offline status and buffer full condition (see “Busy Polarity” above).

XON/XOFF Handshaking

Possible Values: Off*, On

XON/XOFF Off

Enables or disables the transmission of the XON and XOFF characters from the printer to the host to control data flow to the printer. XOFF will be sent whenever the printer goes offline or the serial buffer is full. XON will be sent when it is again ready to receive characters.

ETX/ACK Handshaking

Possible Values: Off*, On

ETX/ACK Off

Enables or disables the ACK response to receipt of the ETX character. This handshake method is useful for conditions where there are long transmission line delays such as telephone lines, which may be routed through satellites. An ACK character will be returned to the host computer after an ETX character is received and processed. ETX characters used for handshaking cannot be part of an escape sequence.

RTS/CTS Handshaking

Possible Values: Power On/Off*

RTS/CTS OFF

If your Host system requires or supports hardware handshaking for data flow control, it may be useful to change this parameter to ON. This may apply especially to older Host systems using Full-duplex communications.
