for Windows Vista, Windows XP/2000/2003/NT/ME/98/95

Communication Control
The SuperCom RS-232 ActiveX is a professional serial communication component library (OLE Custom Control) for serial communication interfaces (RS-232, RS-422, RS-485). The SuperCom RS-232 ActiveX supports common Windows 32 bit development environment and provides the programmer with properties, methods and the events. It's downward compatibility with the MSComm custom control makes it very easy to integrate in existing applications. Replace MSComm with ease.

Time is valuable. Developing communication software with the SuperCom RS-232 ActiveX is extremely easy and starts by placing the ActiveX icon on a Windows Form.

Communications Events
An application using the SuperCom ActiveX can be event driven. The SuperCom ActiveX reports the events OnComm, OnDataPacket, OnModem and OnFileInfo. These events enable the application to manage other tasks simultaneously while communications or file transfer last.

Enhanced Communications Events
The enhanced event reporting mechanism in SuperCom RS-232 ActiveX enables you to receive events on any defined character (e.g. EOF(26), STX, ACK, NAK, etc). The SuperCom ActiveX reports about 30 different communications events.

Polling Mode
The SuperCom ActiveX also supports the polling mode of operation. This means to obtain with methods and properties the state of the status lines and to check the data flow for communication errors without reacting to events.

File Transfer
High speed file transfers tasks are very easy to be accomplished. The following widely used standard protocols ZMODEM, YMODEM/BATCH, YMODEM, XMODEM-1K, XMODEM/CRC, XMODEM, KERMIT and ASCII including their derivates are in the box. The ZMODEM protocol includes important features like "crash recovery", 32bit CRC and "batch file transfer". In fact, these protocols are running very stable since 1991.

Summary
The SuperCom ActiveX is compatible with the MSComm custom control and very easy to integrate into existing applications. It supports any communications configuration supported by the UART and up to 255 ports opened simultaneously by one or different applications.

Long run functions like file transfer, connecting or observing for special data packets or strings are working in background and the application can complete other taks in the meantime and best of all it does not "freeze".

Some SuperCom ActiveX - Properties 

Note: The ComTypes RS-232, RS-422, RS-485 and TAPI are included in the "SuperCom RS-232 ActiveX". The ComType TCP/IP is included in the SuperCom TCP/IP for Windows and ComType ISDN is included in the SuperCom ISDN for Windows. All ComTypes listed above are included in the SuperCom Suite. See also the the available product range for details.

         ' is it available ?

          Call ReadChars
      End If

      If scEvent = SCOMM_EV_CHAR Then
           ' User defined special char received e.g. EOF (26), NAK, STX
         Call HandleSpecialData
      End If

       :

   Private Sub SCom_OnDataPacket(Action, Data)

      ' The parameter Action informs about the Action to take
      ' and/or the current status.
      ' The parameter Data delivers the captured data packet

      ' OK, data available
     If Action = SCOMM_DATAPACKET_OK Then sAction = "DATAPACKET OK"

      ' failed but some captured data may be available
     If Action = SCOMM_DATAPACKET_NOK Then sAction = "DATAPACKET NOK"

      ' error e.g. some wrong parameter in a DP... property
     If Action = SCOMM_DATAPACKET_ERR Then sAction = "DATAPACKET ERR"

      :
      :
  End Sub


  Private Sub SCom_OnFileInfo(Action, Data)

     End Select
  End Sub

  Private Sub SCom_OnModem(Action, TimeLeft)
    If Action = SCOM_CONNECT_FAILED Then
      Debug.Print "CONNECT_FAILED"
    End If

    If Action = SCOM_CONNECT_OK Then
      Debug.Print "CONNECTED ";

... and replacing Microsofts MSComm control and use more than 16 COMM ports was really easy with SuperCom. Thanks!

Wow, within 20 mins of receiving your product my problem with Vista, PDQComm(MSComm clone) and my USB RS232 Adaptor has gone away. I just dropped the control on a form and renamed it - sorted. :) Many thanks for producing this solid product.
