Mono resource

Important: This is not the correct resource to use to configure 3278 emulation.

If true, forces x3270 into X11 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). Note that this is different from monochrome (3278) terminal emulation; it is a holdover from 1990's-era monochrome workstation displays. To configure x3270 to emulate a green-screen IBM model 3278 terminal, specify the value of the model resource as 3278.

In X11 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 X11 display, it will automatically set mono to true.
