These settings control operations on data received from the terminal.

‘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.

‘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. Note ilcuc is not implemented, as one would not be able to issue almost any (lowercase) Unix command, after invoking it.

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.
