DCMD_CHR_FORCE

Force the RTS line to the specified level

Synopsis:

#include <sys/dcmd_chr.h>

#define DCMD_CHR_FORCE_RTS      __DIOT(_DCMD_CHR, 34, int)

Argument	Value
`filedes`	A file descriptor that you obtained by opening the device.
`dcmd`	DCMD_CHR_FORCE_RTS
`dev_data_ptr`	A pointer to a int
`n_bytes`	`sizeof(int)`
`dev_info_ptr`	NULL

This command forces the RTS line to the specified level.

Note:

Not all drivers pay attention to this command.
Forcing RTS to low gives control of the RTS line back to io-char (or to the device for auto RTS). In other words, you could force it low, but it could immediately go back high.

The level of the RTS line: nonzero for high, or zero for low.

None.
