If OPOST is set, output characters are post-processed as indicated by the remaining flags;
otherwise, characters are transmitted without change.
If OLCUC is set, a lower case alphabetic character is transmitted as the corresponding
upper case character. This function is often used in conjunction with IUCLC.
If ONLCR is set, the NL character is transmitted as the CR-NL character pair. If OCRNL is
set, theCR character is transmitted as theNL character. If ONOCR is set, no CR character
is transmitted when at column 0 (first position). If ONRET is set, the NL character is
assumed to do the carriage-return function; the column pointer is set to 0 and the delays
specified for CR are used. Otherwise, theNL character is assumed to do just the line-feed
function; the column pointer remains unchanged. The column pointer is also set to 0 if
the CR character is actually transmitted.
The delay bits specify how long transmission stops to allow for mechanical or other
movement when certain characters are sent to the terminal. In all cases, a value of 0 indi-
cates no delay. If OFILL is set, fill characters are transmitted for delay instead of a timed
delay. This is useful for high baud rate terminals that need only a minimal delay. If
OFDEL is set, the fill character isDEL; otherwise it is NULL.
If a form-feed or vertical-tab delay is specified, it lasts for about 2 seconds.
Newline delay lasts about 0.10 seconds. If ONLRET is set, the carriage-return delays are
used instead of the newlinedelays. If OFILL is set, two fill characters are transmitted.
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 transmits four fill characters.
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.
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.
