#define TIOCLGET        _IOR('t', 124, int)

Arguments to ioctl():

Argument	Value
`fd`	A file descriptor that you obtained by opening the device

Additional argument	A pointer to an int

Description:

This command gets the current local modes. It's implemented as a call to tcgetattr() to get the current settings.

Input:

None.

Output:

The current bit settings; a combination of zero or more of the following:

ECHO: Enable echo.
ECHOE: Echo ERASE as destructive backspace.
ECHOK: Echo KILL as a line erase.
ECHONL: Echo \n, even if ECHO is off.
ICANON: Canonical input mode (line editing enabled).
IEXTEN: QNX Neutrino extensions to POSIX are enabled.
ISIG: Enable signals.
NOFLSH: Disable flush after interrupt, quit, or suspend.
TOSTOP: Send SIGTTOU for background output.

These are the same bits that appear in the c_lflag member of the termios structure.
