IT a form feed delay or vertical tab delay is specified, it lasts for
about 2 seconds.
The newline delay lasts about 0.10 seconds. If ONLRET is set, the
carriage-return delays are used instead of the newline delays. If
OFILL is set, two fill characters will be transmitted.
The carriage-return delay, type 1, is dependent on the current
column position. Type 2 is about 0.10 seconds, and type 3 is
about 0.15 seconds. If OFILL is set, delay type 1 transmits two
fill characters, and type 2, four fill characters.
The horizontal tab delay, type 1, is dependent on the current
column position. Type 2 is about 0.10 seconds. Type 3 specifies
that tabs are to be expanded into spaces. If OFILL is set, two fill
characters are transmitted for any delay.
The backspace delay lasts about 0.05 seconds. If OFILL is set,
one fill character is transmitted.
The actual delays depend on line speed and system load.
The initial output control value is all bits clear.
The c cflag field describes the hardware control of the terminal.
