You're on the right track, that's exactly how you should be doing
it. However,
there is a bug in the Visor Edge OS, and in any Handspring device using the
3.5.2 v1.4 update which causes the winErase blitter mode to fail. Use winMask
instead, and it should work:
WinSetTextColor( (1<<depth)-1 ); // 255 for 8 bit mode, 15 for 4 bit mode, etc
WinSetBackColor( 0 );
WinSetDrawMode( winMask );
WinPaintChars( txt, len, x, y );
WinSetTextColor( indexOfDesiredTextColor );
WinSetBackColor( 0 );
WinSetDrawMode( winOverlay );
WinPaintChars( txt, len, x, y );
