TTYFLAGS(8) BSD System Manager's Manual TTYFLAGS(8)
ttyflags - set device-specific flags for terminals
ttyflags [-pv] [-a | tty ...]
ttyflags sets the device-specific flags for terminals, based on the flags found on the terminal's line in /etc/ttys. The options are as follows: -a Set the flags for all terminals in /etc/ttys. -p Print out flag information about each terminal, instead of set- ting anything. -v Be verbose about what the terminal's flags will be set to. The tty arguments are optional, but must not be specified if the -a flag is used. If specified, the tty arguments should be the base names of the ttys, as found in /etc/ttys.

The ttyflags utility appeared in NetBSD 0.9A.
The conditions on which to report an error are ill-defined. ttyflags tries to report all significant errors, perhaps going over-board at times. MirBSD #10-current March 30, 1994 1
