SuperCom™ ISDN

---

The Communication Toolkit for ISDN in Windows Vista, Windows XP/2000/NT/ME/9x

Looking for ZMODEM over ISDN ?

SuperCom for ISDN is able to connect and transmit data over ISDN lines. The easy to use SuperCom API handles dialup and data transfer the known way.

SuperCom for ISDN provides an optimized Low Level Engine, which handles simultaneously connections, buffers data and generates events. This engine provides maximum functionality but reduces CPU load to minimum.

The Low Level Engine will trigger only wanted events. Unwanted events can be disabled reducing overhead.

The easy to use and portable SuperCom API enables fast implementation of ISDN applications. A client or server application can be build in short time. Most functions and features are well known from the Serial and ISDN communication library.

The available SuperCom functions and protocols are also available over ISDN links i.e. ZMODEM, YMODEM, XMODEM, KERMIT, ASCII, 3964/R, RK512, Modbus and LSV/2 (For the use of the 3964/R and/or LSV/2 protocol the SuperCom 3964/R Protocol Engine and/or the LSV/2 Protocol Module is also needed).

The use of the common SuperCom API enables a move from RS-232 to TCP/IP or from ISDN to TCP/IP to be very smooth and quick. In most cases by simply switching the low level SuperCom DLL.

Complete samples for client and server applications are included in source code and for many developing environments and compilers.

Using the SuperCom Suite enables one single application to handle simultaneously connections through RS-232, TCP/IP and ISDN. Building applications like a gateway from RS-232 to ISDN is now easy done.

Sample - Connecting

The following sample shows how easy it is to use the SuperCom API with different programming languages.

DLL API
In order to receive events the application must provide an InfoProc*. The InfoProc is optional but very handy in many situation. Using the InfoProc the application can receive progress information, get informed about the time left to complete a call or even cancel the connection attempt.

   int InfoProc(Com, Action, TimeLeft, Data)
   {
      if (Action==acCONNECT_INFO)
      {
         // Received periodically, while in progress
      }
      if (Action==acCONNECT_OK)
      {
         // Connected !
      }
      if (Action==acCONNECT_FAILED)
      {
         // Connection attempt failed
      }

      return infContinue;

   }
      :
      :
     // init  ...
   ComInit(Com);

     // dial  ...
   RS_Dial(Com, "555-1234");

     // now connect ...
   Done = RS_Connect(Com, SEC_60, , InfoProc);
  

   Public Function InfoProc(ByVal Com As Byte, _
                            ByVal Action As Integer, _
                            ByVal TimeLeft As Long, _
                            ByVal Data As Long) As Long

      If SComAction = acCONNECT_INFO  Then
         'Received periodically, while in progress
      End If
      If SComAction = acCONNECT_OK  Then
         ' Connected !
      End If
      If SComAction = acCONNECT_FAILED Then
         ' Connection attempt failed
      End If

      InfoProc = infContinue

   End Function
        :
        :
     ' init  ...
   Call ComInit(Com)

     ' dial  ...
   Call RS_Dial(Com, "555-1234")

     ' now connect ...
   Done = RS_Connect(Com, SEC_60, , InfoProc)
  

   Function InfoProc (Com:Byte; Action:WORD; TimeLeft:TDWORD; Data:PFDATA):Integer;
   Begin
      InfoProc:=infCONTINUE; { Continue }

      If (Action = acCONNECT_INFO) Then
      Begin
         // Received periodically, while in progress
      End;
      If (Action = acCONNECT_OK) Then
      Begin
        // Connected !
      End;
      If (Action = acCONNECT_FAILED) Then
      Begin
        // Connection attempt failed
      End;
        :
   End;
      :
      :
     // init  ...
   ComInit(Com);

     // dial  ...
   RS_Dial(Com, "555-1234");

     // now connect ...
   Done = RS_Connect(Com, SEC_60, , @InfoProc);
  

   public int InfoProc(int Com, short Action, int Data, int pNotUsed)
   {
      switch (Action)
      {
         case SuperCom.acCONNECT_INFO:
               // Received periodically, while in progress
              break;
         case SuperCom.acCONNECT_FAILED:
               // Connection attempt failed
              break;
         case SuperCom.acCONNECT_OK:
               // Connected !
              break;
         case SuperCom.acUSERBREAK:
              // break by user
              break;
      }
      return SuperCom.infCONTINUE;
   }
      :
     // init  ...
   SuperCom.ComInit(Com);

     // dial  ...
   SuperCom.RS_Dial(Com, "555-1234");

     // now connect ...
   Done = SuperCom.RS_Connect(Com,SuperCom.SEC_10,,,cbConnectInfoFunc);
  

The connection set-up can run completely in background. The application receives events about the progress.

ActiveX API

  Private Sub SCom1_OnModem(ByVal Action As Integer, ByVal TimeLeft As Long)

     If Action = SCOM_CONNECT_FAILED Then
       Form4.CTL_INFO.Text = "CONNECT FAILED"
     End If

     If Action = SCOM_CONNECT_OK Then
       Form4.CTL_INFO.Text = "CONNECTED"
     End If

     If Action = SCOM_CONNECT_INFO Then
       Form4.CTL_INFO.Text = "CONNECT INFO"
     End If

  End Sub

      :
      :

  SCom1.PortOpen=True ' setup a link
      :
  SCom1.ConnectAddress="555-1234"
      :
  SCom1.Connect=True ' now connect

      :

  

The connection set-up runs completely in background. The application receives events about the progress.

It does not matter which communication link it uses (Serial, TCP/IP or ISDN) it will require one common SuperCom API to use. The learning curve is extremely low with SuperCom!
