+The original ncurses (as pcurses in 1986) set \fBnoraw\fP and \fBcbreak\fP

+.IP
+Since 1995, ncurses has provided signal handlers for INTR and QUIT
+(e.g., \fB^C\fP or \fB^\\\fP).
+With the \fBnoraw\fP and \fBcbreak\fP settings,
+those may catch a signal and stop the program,
 where other implementations allow one to enter those characters in the buffer.
+.bP
+Starting in 2021 (ncurses 6.3), \fBgetnstr\fP sets \fBraw\fP,
+rather than \fBnoraw\fP and \fBcbreak\fP for better compatibility with
+SVr4-curses, e.g., allowing one to enter a \fB^C\fP into the buffer.
