Parity
When this option is set to None, parity checking is disabled. The
parity bit, if used, provides a basic form of error detection. See
your computer manual and software documentation for the
proper setting.
Stop Bit
Use this option to set the number of stop bits for each character
of information sent to the printer. Stop bits signal the end of a
character.
XOn/XOff
Use this option to set the XOn/XOff communications protocol to
On, Off, or Robust. You can use XOn/XOff protocol in
combination with the DTR option setting. If set to Robust, the
printer sends an XOn signal every one second when the printer is
available to receive data.
DTR
Use DTR (Data Terminal Ready) to turn the printer's DTR
communications protocol on or off. You can use DTR protocol in
combination with the XOn/XOff option setting.
DSR
When DSR (Data Set Ready) is Off, the signal level is permanently
set High, allowing the printer to send data to the computer. For
most communications purposes, this option should be set to Off
(Signal level High). When DSR is On, data is sent to the computer
only when DSR is High.
