int v24SetRTS

(v24_port_t* port, int NewState )


Documentation

This means, v24OpenPort isn't called with V24_RTS_CTS. If hardware handshaking is used while calling this function, it aborts and returns V24_E_ILLPARM as error.

The values returned are: V24_E_OK, V24_E_ILLHANDLE, V24_E_ILLPARM, V24_E_NOT_IMPLEMENTED.

Parameters:
port - pointer to handle of the opened port.
NewState - the new state to set DTR to.
Returns:
(int) the V24_* error code.
