		Whether support Ctrl-c/x event.  Enabled automatically for console

		in the Termios c_lflag.

		REVISIT:  This implementation is compliant but incomplete.  The
		c_lflag ISIG bit normally enables/disables INTR, QUIT, SUSP, and
		DSUSP character processing.  The relationship between these names,
		standard signals, and typical key presses are as follows:

		  INTR   SIGINT   Ctrl-C  ETX(0x03) Interrupt
		  KILL   SIGKILL  Ctrl-U  NAK(0x15) Kill
		  QUIT   SIGQUIT  Ctrl-\  FS (0x1c) Quit
		  SUSP   SIGTSTP  Ctrl-Z  SUB(0x1a) Suspend
		  DSUSP  SIGTSTP  Ctrl-Y  EM (0x19) Delayed suspend

		Additional requirements:
		  - SIGKILL cannot be caught or ignored.  Compared to SIGTERM which
		    is like SIGKILL but can be caught or ignored.
		  - SIGQUIT is like SIGINT but causes generation of a core dump
		  - SIGSTOP cannot be caught or ignored.  SIGTSTP is like SIGSTOP but
		    can be caught or ignored.
		  - The delayed suspend (DSUSD) is like suspend (SUPD), except that
		    the suspension is delayed until the next read operation

		Ctrl-D (EOT 0x04) normally should not generate a signal but, instead,
		should cause an immediate End-of-File result.

config TTY_SIGINT_CHAR
	hex "Serial parse SIGINT characters"
	default 0x03 if SERIAL_CONSOLE
	default 0x04 if !SERIAL_CONSOLE
	depends on TTY_SIGINT
	---help---
		Use ASCII 0x03 (Ctrl-c) or 0x04 (ctrl-d) inputs to determine whether
		to send a SIGINT event.  Other characters may also be selected.

		REVISIT:  Traditionally Ctrl-C would generate SIGINT.  Ctrl-D is the
		End-of-File character that should close the stream.

config TTY_SIGTSTP
	bool "Support SIGTSTP"
	default n
	---help---
		Whether support Ctrl-z event.  Enabled automatically for console
		devices.  May be enabled for other serial devices using the ISIG bit
