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.  Note ilcuc is not implemented, 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.
