int nocrmode(void);
Description:
- cbreak() and nocbreak() toggle cbreak mode. In cbreak mode,
- characters typed by the user are made available immediately, and
- erase/kill character processing is not performed. In nocbreak
- mode, typed characters are buffered until a newline or carriage
- return. Interrupt and flow control characters are unaffected by

In PDCurses, the meta() function sets raw mode on or off.
