SPORT_READ_LINE

Serial Port I/O Function: Reads a record from the specified port. This routine stalls until at least one record has been read. This routine is only available for Windows.

Module

USE IFPORT

result = SPORT_READ_LINE (port,buffer[, count])

port

(Input) Integer. The port number.

buffer

(Output) Character*(*). The data that was read.

count

(Output; optional) Integer. The count of bytes read.

Results

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

This routine will only return when a line terminator has been seen - as defined by the mode specified in the SPORT_CONNECT( ) call.

NOTE:

CR and LF characters may not be returned depending on the mode specified in the SPORT_CONNECT( ) call.

Example

USE IFPORT
INTEGER(4)      iresult
INTEGER         count
CHARACTER*1024  rbuff

iresult = SPORT_READ_LINE( 2, rbuff, count )
END
