| on_off |

0 ... 1 |
XON/XOFF mode on or off |
When the iLCD is set to the terminal mode, the XON/OFF mode becomes relevant. If XON/XOFF is on (on_off = 1) the iLCD module sends a [XOFF] character (0x13) when the input buffer gets filled with ½ ("high water") of the total size and a [XON] character (0x11) when the buffer is emptied to 1/3 ("low water") of the total size.
Note
- The total size of the input buffer is 128 characters for all iLCD Controllers up to DPC3050 and 1024 characters for DPC3080 and higher. The command Get Input Buffer Size can be used to request the size of the input buffer.
- This is a standard mechanism used for terminals which do not have the ability to use hardware handshake signals (see some general information about this issue in the chapters Command Structure and Terminal Mode).
- XON/XOFF mode is not active when the module is in standard command mode.
- The default value for on_off is 0, but can be modified on the "Settings" page of iLCD Manager XE. It will be automatically set to default on startup and by the commands Reset All or Reboot Panel Controller.
