Busy Signal Polarity

Possible Values: Lo*, Hi

Busy Polarity Low

This item selects the polarity of the busy signal (pin 11 of the RS-232C interface). Busy is set whenever the printer is offline, the serial input buffer is full, or another interface port is currently active.

Data Terminal Ready

Possible Values: Power On/Off*

Online/Offline

Busy/Not Busy

DTR Power On/Off

Selects the condition to be reflected by the DTR signal (pin 20 of the RS- 232C interface). In most cases, especially those involving a MODEM, this

signal should be set to indicate Power On/Off. Selecting 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 the printer is again ready to receive characters.
