I was under the impression you could now set individual tty driver
flags if you wanted. Quoting the man page...
Terminal modes to be used for the output of the message, for input of the
login name, and to leave the terminal set as upon completion, are derived
from the boolean flags specified. If the derivation should prove inade-
quate, any (or all) of these three may be overridden with one of the c0,
c1, c2, i0, i1, i2, l0, l1, l2, o0, o1, or o2 numeric specifications,
which can be used to specify (usually in octal, with a leading '0') the
exact values of the flags. These flags correspond to the termios
c_cflag, c_iflag, c_lflag, and c_oflag fields, respectively. Each these
sets must be completely specified to be effective. The f0, f1, and f2
are excepted for backwards compatibility with a previous incarnation of
the TTY sub-system. In these flags the bottom 16 bits of the (32 bits)
value contain the sgttyb sg_flags field, while the top 16 bits represent
the local mode word.
I believe that clocal is a bit of c_cflag, though my memory is weak.
