SPORT_SET_TIMEOUTS (W*32)

Serial Port I/O Function: Sets the user selectable timeouts for the serial port.

Module

USE IFPORT

構文

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.

Results

The result type is INTEGER(4). The result is zero if successful; otherwise, a Windows* OS error value.

Note icon

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.
