SPORT_SET_TIMEOUTS (W*32, W*64)

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

Module: USE IFPORT

Syntax

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* error value.

Note

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.
