SPORT_CONNECT (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: Establishes the connection to a serial port and defines certain usage parameters.

Module

USE IFPORT

result = SPORT_CONNECT (port [,options])

port

(Input) Integer. The port number of connection. The routine will open COM n, where n is the port number specified.

options

(Input; optional) Integer. Defines the connection options. These options define how the nnn_LINE routines will work and also effect the data that is passed to the user. If more than one option is specified, the operator .OR. should be used between each option. Options are as follows:

Option	Description
DL_TOSS_CR	Removes carriage return (CR) characters on input.
DL_TOSS_LF	Removes linefeed (LF) characters on input.
DL_OUT_CR	Causes SPORT_WRITE_LINE to add a CR to each record written.
DL_OUT_LF	Causes SPORT_WRITE_LINE to add a LF to each record written.
DL_TERM_CR	Causes SPORT_READ_LINE to terminate READ when a CR is encountered.
DL_TERM_LF	Causes SPORT_READ_LINE to terminate READ when a LF is encountered.
DL_TERM_CRLF	Causes SPORT_READ_LINE to terminate READ when CR+LF is encountered.

If options is not specified, the following occurs by default:

(DL_OUT_CR .OR. DL_TERM_CR .OR. DL_TOSS_CR .OR. DL_TOSS_LF)

This specifies to remove carriage returns and linefeeds on input, to follow output lines with a carriage return, and to return input lines when a carriage return is encountered.

Results

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

Example

USE IFPORT
INTEGER(4) iresult
iresult =  SPORT_CONNECT( 2 )
END
