FiveWin + Com Port with Terminal Server

FiveWin + Com Port with Terminal Server

Postby ali » Fri Nov 04, 2011 12:19 pm

Hi People!

Do somebody work with Windows Terminal Server + FiveWin + COM Port redirection?

I have edit a litte sample Programm from Enrico. That read the Com Port imput. On a Local Machine it works fine but on a Terminal Server I get no DATA. With a other Programm (no FW) it works. I hope someone can help me.

Here the source:

Code: Select all  Expand view

// Working sample of a simple ASCII terminal program - Developed by Enrico M. Giordano

#include "Fivewin.ch"

FUNCTION MAIN()

    LOCAL oDlg

    LOCAL oGet, cTxt := ""

    LOCAL nCom

    DEFINE DIALOG oDlg;
           SIZE 500, 500;
           TITLE "Terminale"

    @ 0, 0 GET oGet VAR cTxt MEMO READONLY

    oGet:bKeyDown = { | nKey | Tasti( nCom, nKey ) }

    ACTIVATE DIALOG oDlg;
             ON INIT ( oGet:AdjClient(),;
                       nCom := APRICOM( oDlg, oGet ),;
                       IF( nCom < 0, oDlg:End(), ) );
             CENTER

    IF nCom >= 0; CLOSECOMM( nCom ); ENDIF

    RETURN NIL


STATIC FUNCTION TASTI( nCom, nKey )

    SENDSTR( nCom, CHR( nKey ) )

    RETURN NIL


STATIC FUNCTION APRICOM( oDlg, oGet )

    LOCAL nCom, cDcb

    BEGIN SEQUENCE
        nCom = OPENCOMM( "COM1", 2048, 128 )

        IF nCom < 0
            ? "Errore di apertura della porta di comunicazione."
            BREAK
        ENDIF

        BUILDCOMMDCB( "COM1:9600,N,8,1", @cDcb )

        IF !SETCOMMSTATE( nCom, cDcb )
            ? "Errore di impostazione della porta di comunicazione."
            BREAK
        ENDIF

        oDlg:bCommNotify = { | nCom | Connect( nCom, oGet ),;
                                      EnableCommNotification( nCom, oDlg:hWnd, 1, -1 ) }

        IF !ENABLECOMMNOTIFICATION( nCom, oDlg:hWnd, 1, -1 )
            ? "Errore di abilitazione della notifica."
            BREAK
        ENDIF
    RECOVER
        nCom = -1
    END SEQUENCE

    RETURN nCom


STATIC FUNCTION CONNECT( nCom, oGet )

    LOCAL cStr

    ENABLECOMMNOTIFICATION( nCom, 0, 1, -1 )

    cStr = RECEIVESTR( nCom )

    cStr = STRTRAN( cStr, CHR( 13 ), "" )
    cStr = STRTRAN( cStr, CHR( 10 ), CRLF )

    oGet:Append( cStr )

    RETURN NIL


STATIC FUNCTION SENDSTR( nCom, cString )

    LOCAL nBytes := WRITECOMM( nCom, cString )

    RETURN nBytes = LEN( cString )


STATIC FUNCTION RECEIVESTR( nCom )

    LOCAL cBuf := SPACE( 1000 )

    RETURN LEFT( cBuf, READCOMM( nCom, @cBuf ) )

Are you sure that com port is COM1 on terminal server? And, anyway, do you get one of the error messages that are in the sample? Or any other error message?

Hi!

With the no FW Program I get data from COM 1. The Port is correct. No error messages. nothing happend. Is it possible to set the timer to receiving Data up to give the Prog. more time?

Best regards

A timer is needed only for polling technique not for the better interrupt technique that my sample uses.
