|Boolean||false (see Note)|
If true, forces x3270 into X11 monochrome window mode. The display window and all pop-ups and menus are rendered with a single foreground color and a single background color (by default, black on white).
Note that X11 monochrome window mode is different from monochrome (3278) terminal emulation. To configure x3270 to emulate a green-screen IBM model 3278 terminal -- with the text properly displayed in green -- specify the value of the model resource as one of the models of 3278 (or just 3278, which defaults to 3278-4-E).
This resource is primarily for testing purposes.
