(i.e. TCSETS). The original I/O control command and

M_IOCTL message are stored for use

M_IOCACK.

TIOCGLTC

The ldterm module returns the ltchars information based on the interpretation of the

current content of the POSIX termios structure maintained in

ldterm.

TIOCLBIS, TIOCLBIC, TIOCLSET

These commands set the BSD 4.3 ﬂags information, deﬁned in

.For

TIOCLBIS and TIOCLBIC, the argument is a pointer to an

int whose value is a mask con-

taining ﬂags to be set/clear. For

TIOCLSET, the argument is a pointer to an

int whose value

is a new set of ﬂags to be set. The

ldterm module converts the message to a POSIX ter-

mios M_IOCTL, then forwards the POSIX

termios M_IOCTL message with a corresponding

POSIX

termios command (i.e. TCSETS). It stores the original I/O control command and

M_IOCTL message to be used on M_IOCACK.

TIOCLGET

The ldterm module returns the BSD 4.3 ﬂags information based on the interpretation of the

current content of the POSIX termios structure maintained in

ldterm.

TIOCSTI This command takes an argument of a pointer to a character and pretends that the character

was typed on the terminal. The user must either have the

DEVOPS privilege or have read per-

mission on the controlling terminal against which the ioctl is issued. See privileges (5) for more

information about privileged access on systems that support ﬁne-grained privileges.

FIONREAD

This command takes an argument of a pointer to an integer and returns the number of

immediately readable characters.
