3. MTCRTS

This function, only valid when hardware flow control is turned off (see

MHWFLOW), is used to turn RTS on or off.

Syntax for SCO UNIX/XENIX

#define MTCRTS 0x403

#define TurnON 1

#define TurnOFF 0

ioctl(moxa_fd, MTCRTS, TurnON);

ioctl(moxa_fd, MTCRTS, TurnOFF);

Syntax for UNIX SVR4

#include <sys/stropts.h>

#include <sys/sysmacros.h>

#define MTCRTS 0x403

#define TurnON 1

#define TurnOFF 0

struct strioctl ioc;

int setting;

setting = TurnON /* or TurnOFF */;

ioc.ic_cmd = MTCRTS;

ioc.ic_timout = 0;

ioc.ic_len = sizeof(int);

ioc.ic_dp = (char *)&setting;

ioctl(moxa_fd, I_STR, &ioc);

4. MTCDTR

This function, only valid when hardware flow control is turned off (see

MHWFLOW), is used to turn DTR on or off.

Syntax for SCO UNIX/XENIX

#define MTCDTR 0x404

#define TurnON 1

#define TurnOFF 0

ioctl(moxa_fd, MTCDTR, TurnON);

ioctl(moxa_fd, MTCDTR, TurnOFF);
