19.2.2 Input settings

These settings control operations on data received from the terminal.

‘ignbrk’ ¶

Ignore break characters. May be negated.

‘brkint’ ¶

Make breaks cause an interrupt signal. May be negated.

‘ignpar’ ¶

Ignore characters with parity errors. May be negated.

‘parmrk’ ¶

Mark parity errors (with a 255-0-character sequence). May be negated.

‘inpck’ ¶

Enable input parity checking. May be negated.

‘istrip’ ¶

Clear high (8th) bit of input characters. May be negated.

‘inlcr’ ¶

Translate newline to carriage return. May be negated.

‘igncr’ ¶

Ignore carriage return. May be negated.

‘icrnl’ ¶

Translate carriage return to newline. May be negated.

‘iutf8’ ¶

Assume input characters are UTF-8 encoded. May be negated.

‘ixon’ ¶

Enable XON/XOFF flow control (that is, Ctrl-S/Ctrl-Q). May be negated.

‘ixoff’ ¶

‘tandem’

Enable sending of stop character when the system input buffer is almost full, and start character when it becomes almost empty again. May be negated.

‘iuclc’ ¶

Translate uppercase characters to lowercase. Non-POSIX. May be negated. There is no ‘ilcuc’ setting, as one would not be able to issue almost any (lowercase) Unix command, after invoking it.

‘ixany’ ¶

Allow any character to restart output (only the start character if negated). Non-POSIX. May be negated.

‘imaxbel’ ¶

Enable beeping and not flushing input buffer if a character arrives when the input buffer is full. Non-POSIX. May be negated.
