Thus a back buffer is used * in this driver. * * ******** UPDATE ********* * I have added a "VT-100 Compatible mode" that allows the driver to support * control-sequence code. This greatly reduce flickering and eliminate the need * for the back-buffer. But it is optional since all displays cannot support them. * Here are the codes: * Delete the display (but does not move the cursor) : * "ESC [ 2 J" (0x1b 0x5b 0x32 0x4a) * Position the cursor : * "ESC [ YY ; XX H" ( 0x1b 0x5b YY 0x3b XX 0x48 ) where YY is the ascii for the line * number, and XX is the ascii for the column number ( first line/column is '1', not zero) * Delete to the end of line from current cursor position : * "ESC [ 0 K" ( 0x1b 0x5b 0x30 0x4b ) * Set Country Code : * "ESC R NN" (0x1b 0x52 NN) where NN is the country code *in byte, NOT ascii*. * The default is 0 (USA), see below for specific countries. * the list of accessible characters page are available on this page : * http://www.wincor-nixdorf.com/internet/com/Services/Support/TechnicalSupport/POSSystems * /Manuals/BA
