Hi,
Does anyone know of a way to manipulate the modem control lines from userland?
See <sys/ttycom.h>, in particular the following ioctls:
#define TIOCMSET _IOW('t', 109, int) /* set all modem bits */
#define TIOCMBIS _IOW('t', 108, int) /* bis modem bits */
#define TIOCMBIC _IOW('t', 107, int) /* bic modem bits */
#define TIOCMGET _IOR('t', 106, int) /* get all modem bits */
#define TIOCM_LE 0001 /* line enable */
#define TIOCM_DTR 0002 /* data terminal ready */
#define TIOCM_RTS 0004 /* request to send */
#define TIOCM_ST 0010 /* secondary transmit */
#define TIOCM_SR 0020 /* secondary receive */
#define TIOCM_CTS 0040 /* clear to send */
#define TIOCM_DCD 0100 /* data carrier detect */
#define TIOCM_RI 0200 /* ring indicate */
#define TIOCM_DSR 0400 /* data set ready */
#define TIOCM_CD TIOCM_DCD
#define TIOCM_CAR TIOCM_DCD
#define TIOCM_RNG TIOCM_RI
