SuperCom™ ActiveX

---

ActiveX API for Windows 7, Vista, Windows XP/2000/Server 2003/Server 2008/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 development environment and provides the programmer with properties, methods and the events in order to develop data communication applications. It's downward compatibility with the MSComm control makes it very easy to integrate into existing applications. See how to replace MSComm with ease.

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

SuperCom also provides intelligent functions that considerably speed-up the development process and produce fast, reliable solutions avoiding delaying or blocking of your application.

Communications Events

Applications using the SuperCom ActiveX can work event driven. The SuperCom ActiveX reports the events OnComm, OnDataPacket, OnConnect and OnFileInfo. The reported events enable the application to manage other tasks simultaneously while communications or file transfer last.

The OnComm event reports changes in the status lines e.g. CTS, DSR or RING, when characters were received or when communication errors occur. The OnDataPacket event informs about the status of observed data packets for instance if an observed data packet is received. The OnConnect event provides information during the setup of a connection (e.g. modem dialup). The OnFileInfo event provides status information during the file transfer. A progress dialog and/or file transfer statistics can be updated.

Enhanced Communications Events

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

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 the need to react on events.

File Transfer

High speed file transfers tasks are very easy to accomplish. The following widely used standard protocols ZMODEM, YMODEM/BATCH, YMODEM, YMODEM-G, XMODEM-1K, XMODEM/CRC, XMODEM, KERMIT and ASCII are included. The SuperCom ZMODEM protocol includes important features like "crash recovery", 32bit CRC and "batch file transfer". In fact, these protocols are running very stable since 1991.

MSComm Compatible

The SuperCom ActiveX is compatible with the MSComm control and thus it's very easy to update existing applications using it. Replacing MSComm with SuperCom ActiveX is a fast and smooth operation.

Summary

Using the SuperCom ActiveX up to 255 ports / connections can be opened simultaneously within the same application.

Start as many instances of your application - no limit set.

Lengthy functions like file transfer, connecting or observing the data stream for special data packets or strings are working in background and your application can complete other taks in the meantime. It does not "freeze" waiting on a lengthy function to complete.

(The following briefly shows a simple example of the control operation using Visual Basic)

   Sub Form_Load()

         ' Select COM2
      SCom.CommPort = 2
