PRINTER CONFIGURATION
54
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 (see “Automatic Port
Switching” earlier in this section).
Data Terminal Ready
DTR
Power On/Off
Possible Values: Power On/Off*
Online/Offline
Busy/Not Busy
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).
RTS/CTS Handshaking
RTS/CTS
Off
Possible Values: Off*, On
Enables or disables RTS/CTS hardware handshaking. If enabled, RTS
takes on the alternate meaning of “ready to receive”. The printer will assert
RTS when it is capable of receiving data. When the printer is off line, the
serial input buffer is full, or another interface port is currently active, the
printer will de-assert RTS. Likewise, the host computer will assert CTS
when it is capable of receiving data.
XON/XOFF Handshaking
XON/XOFF
Off
Possible Values: Off*, On
