Remarks
restorecrtmode restores the original video mode detected by initgraph.
This function can be used in conjunction with setgraphmode to switch back and forth between text and graphics modes, textmode should not be used for this purpose; use it only when the screen is in text mode, to change to a different text mode.
Return value
None.
