Serial Port I/O Function: Sets the user selectable timeouts for the serial port.
result = SPORT_SET_TIMEOUTS (port [,rx_int] [,tx_tot_mult] [,tx_tot_const])
port |
(Input) Integer. The port number. |
rx_int |
(Input; optional) INTEGER(4). The receive interval timeout value. |
tx_tot_mult |
(Input; optional) INTEGER(4). The transmit multiplier part of the timeout value. |
tx_tot_const |
(Input; optional) INTEGER(4). The transmit constant part of the timeout value. |
The result type is INTEGER(4). The result is zero if successful; otherwise, a Windows* OS error value.
This routine must not be used when any I/O is pending. Since a read operation is always pending after any I/O has been started, you must first call SPORT_CANCEL_IO before port parameters can be changed.
