while ``secure'' (if ``on'' is also specified) allows users with a
uid of 0 to login on
this line.
The flags ``local'', ``rtscts'', ``mdmbuf'', and ``softcar''
modify the default behaviour of the terminal line, and their actions
are driver dependent.
The ``local'' flag causes the driver to
treat the line as if it locally connected.
The ``rtscts'' flag
instructs the driver to use RTS/CTS hardware flow control, if
possible.
The ``mdmbuf'' flag instructs the driver to use
DTR/DCD flow control, if possible.
The ``softcar'' flag causes the driver to ignore
hardware carrier on the line.
These flag fields should not be quoted.
