The control-modes field c_cflag specifies communication control for terminals.
The value of c_cflag controls characteristics of
the communications-port to a terminal-device, but
the underlying hardware may fail to support all c_cflag values (see
A communication-port other than an asynchronous serial
connection may ignore some of the control-modes;
for example, if an attempt is made to set the baud-rate
on a network-connection to a terminal on another host,
the baud-rate may or may not be set on the connection between
the terminal and the machine it is directly connected to.
