This question is related to pty terminal packet mode TIOCPKT
What the linux way of enabling packet mode? I could not find I_PUSH working when passed in ioctl function.
回答1:
TIOCPKT is exactly what you want, according to the tty_ioctl(4) man page: the argument is a pointer to an integer which is non-zero to enable packet mode, or zero to disable it.
