Remote mode

A feature known as remote mode is available with the pseudo-tty subsystem. This feature is used for applications that perform the canonical function normally done by the ldterm module and tty driver. The remote mode allows applications on the master-side to turn off the canonical processing. An ioctl TIOCREMOTE with a nonzero parameter [ioctl(fd, TIOCREMOTE, 1)] is issued on the master-side to enter the remote mode. When this occurs, an M_CTL message with the command MC_NO_CANON is sent to the ldterm module indicating that data should be passed when received on the read-side and no canonical processing is to take place. The remote mode may be disabled by ioctl(fd, TIOCREMOTE, 0).
