SunOS 5.5 Ioctl Requests termio(7I)

TIOCGWINSZ The argument is a pointer to a winsize structure. The terminal driver’s

notion of the terminal size is stored into that structure.

TIOCSWINSZ The argument is a pointer to a winsize structure. The terminal driver’s

notion of the terminal size is set from the values speciﬁed in that struc-

ture. If the new sizes are different from the old sizes, aSIGWINCH sig-

nal is set to the process group of the terminal.

TIOCMBIS The argument is a pointer to an int whose value is a mask containing

modem control lines to be turned on. The control lines whose bits are

set in the argument are turned on; no other control lines are affected.

TIOCMBIC The argument is a pointer to an int whose value is a mask containing

modem control lines to be turned off. The control lines whose bits are

set in the argument are turned off; no other control lines are affected.

TIOCMGET The argument is a pointer to an int. The current state of the modem

status lines is fetched and stored in the int pointed to by the argument.

TIOCMSET The argument is a pointer to an int containing a new set of modem con-

trol lines. The modem control lines are turned on or off, depending on

whether the bit for that mode is set or clear.
