The monochrome devices seem to start in 1-bit, but I need to change to 4-bit. After looking again at Aaron's toggle program, I still don't really understand how this works. WinScreenMode as used below doesn't seem to do anything. ----------------------------------------------------------- tmpdepthP=4; WinScreenMode(winScreenModeSet,NULL,NULL,&tmpdepthP,NULL); ----------------------------------------------------------- >From toggle, I get the below. (Where is this documented?) This make it so the *second* time I run, I get 4-bits. (Changes the depth after the program exits.) ----------------------------------------------------------- FtrSet(sysFtrCreator, sysFtrNumDisplayDepth, 4); ----------------------------------------------------------- So how do I change to and from 1-bit and 4-bit?
