ERASE DELETE. If the I CANON flag is set, erases the
preceding character. It does not erase beyond the
start of a line, as delimited by an NL, EOF, or EOL
character.
KILL CONfROL-U. If the ICANON flag is set, deletes the
entire line, as delimited by an NL, EOF, or EOL
character.
EOF CONfROL-D. If the ICANON flag is set when this
character is received, immediately pass to the program
all the characters waiting to be read without
waiting for a newline, and discard the EOF. If there
are no characters waiting, zero characters are passed
to the program to indicate an end-of-file condition.
NL ASCII LF. If the I CANON flag is set, acts as the line
delimiter (\n). It cannot be changed.
EOL ASCII NUL. If the I CANON flag is set, acts as an
additional line delimiter similar to NL .
SUSP CONTROL-Z. If the I S I G flag is set, generates a
S I GT S TP signal that is sent to all processes in the
distinguished process group associated with the terminal.
STOP CONTROL-So If IXON or IXOFF flag is set, temporarily
suspends output. This character is used on
terminals to prevent output from disappearing before
it can be read.
START CONTROL-Q. If the IXON or IXOFF flag is set,
resumes output that has been suspended by a STOP
character.
SWTCH CONTROL-Z. If used by the shell-layering facility,
shl, changes the current layer to the control layer.
The START and STOP characters cannot be changed. The values
for INTR, QUIT, ERASE, KILL, EOF, EOL, and SUSP can be
changed by using tcsetattr(3P). ERASE, KILL, and EOF
characters may be escaped by preceding the character with a \; in
this case, no special function is performed.
c _line specifies the line discipline number for the terminal. The
basic line discipline number is 0; this is currently the only line discipline
supported.
