62.8. Terminal Line Control

The tcsendbreak(), tcdrain(), tcflush(), and tcflow() functions perform tasks that are usually collectively grouped under the term line control. (These functions are POSIX inventions designed to replace various ioctl() operations.)

#include <termios.h>

int tcsendbreak(int fd, int duration);
int tcdrain(int fd);
int tcflush(int fd, int queue_selector);
int tcflow(int fd, int action);
