SPORT_SET_TIMEOUTS (W*S)

インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス

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

Module

USE IFPORT

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.

Example

USE IFPORT
INTEGER(4) iresult
iresult =  SPORT_SET_TIMEOUTS( 2, 100, 0, 1000 )
END
