TerminalSettings.BRKINT (gb.term)

Return or set if a BREAK may interrupts the terminal foreground process.

If IGNBRK is set, a BREAK is ignored. If it is not set but BRKINT is set, then a BREAK causes the input and output queues to be flushed, and if the terminal is the controlling terminal of a foreground process group, it will cause a SIGINT to be sent to this foreground process group.

When neither IGNBRK nor BRKINT are set, a BREAK reads as a null byte (\0), except when PARMRK is set, in which case it reads as the sequence \377 \0 \0.
