SPORT_WRITE_LINE (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: Outputs data, followed by a record terminator, to the specified port.

Module

USE IFPORT

result = SPORT_WRITE_LINE (port,data[,count])

port	(Input) Integer. The port number.
data	(Input) Character(). The data to be output.
count	(Input; optional) Integer. The count of bytes to write. If the value is zero, this number is computed by scanning the data backwards looking for a non-blank character.

Results

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

After the data is output, a line terminator character is added based on the mode used during the SPORT_CONNECT( ) call.

NOTE

When hardware (DTR, RTS, etc.) or software (XON/XOFF) flow controls are used, the functions SPORT_WRITE_DATA and SPORT_WRITE_LINE can write less bytes than required. When this occurs, the functions return the code ERROR_IO_INCOMPLETE, and the return value of parameter count contains the number of bytes that were really written.

Example

USE IFPORT
INTEGER(4) iresult
iresult = SPORT_WRITE_LINE( 2, 'ATZ', 0 )
END
