Mono resource

If true, forces x3270 into monochrome display mode. The display and all menus are rendered with a single foreground color and a single background color (by default, black on white). This is different from monochrome (3278) emulation mode; it is a holdover from monochrome workstation displays.

In monochrome display mode, the foreground color can be changed with the foreground resource, and the background can be changed with the background resource.

Note
If x3270 detects a monochrome display, it will automatically set mono to true.
