Call the "lower half" rxflowcontrol method whenever the number of
characters in the serial RX buffer falls above an upper water mark
level or below a lower watermark level. The default behavior is to
call the rxflowcontrol method only when the RX buffer is empty or
full.

from instance-to-instance.

---help---
As a debug option, many serial bottom half drivers support the TIOCSERGSTRUCT
that allows you to get the internal driver data structure. By default, this
IOCTL is not supported in order to reduce footprint. But if (1) the driver
supports the TIOCSERGSTRUCT ioctl, and (2) this option is selected, then
support for the TIOCSERGSTRUCT will be enabled.

Serial driver supports termios.h interfaces (tcsetattr, tcflush, etc.).
If this is not defined, then the terminal settings (baud, parity, etc).
are not configurable at runtime; serial streams cannot be flushed, etc..

config TTY_SIGINT
bool "Support SIGINT"
default n
---help---
Whether support Ctrl-c/x event. Enabled automatically for console
devices. May be enabled for other serial devices using the ISIG bit
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
in the Termios c_lflag.
