Set terminal attributes
#include <termios.h> int cfmakeraw( struct termios * termios_p );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The cfmakeraw() function sets the terminal attributes as follows:
termios_p->c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP|INLCR|IGNCR|ICRNL|IXON); termios_p->c_oflag &= ~OPOST; termios_p->c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN); termios_p->c_cflag &= ~(CSIZE|PARENB); termios_p->c_cflag |= CS8;
You can get a valid termios control structure for an opened device by calling tcgetattr().
