If you need to capture complete data packets you can also use DPCollect. Immediately when the special character(s) or string(s) is/are received SuperCom places OnComm event while your application can perform other thinks.

Using Triggers not only single characters but complete strings can be observed.

It's easier to use SuperCom's Trigger or EventChar. It's surely time consuming and rather complex to parse every received data string for such data. It's often necessary to react on special characters like SOH, STX, ETX etc. Short samples within the manual and source code samples demostrate how. With the SuperCom ActiveX you can transmit any byte combination with values from 0 to 255 in binary mode (Binary Data Transmission). MSComm failed to transmit binary data properlyīinary data transfer can be tricky or even not possible if the used library doesn't support you. This is possible because of it's high efficient multiprocessing implementation. Setup and run up to 255 concurrent connections doing data transfers or file transfers is realy easy. SuperCom controls up to 255 serial connections or ports simultaneously. Need to control more than 16 serial ports

Try our complete samples found here and perform your stress tests. No memory leaks or other bugs known from MSComm. SuperCom is a mature library used since Windows 95 to replace MSComm. Even file transfers are performed in background. SuperCom does not block while sending or receiving data because it transmits and receives data completely transparent in background. While you are sending or receiving data your application suddenly appears to hang and unstable. Replacing the MSComm with the SuperCom ActiveX you get rid of MSComm run-time errors once for all. Run-time errors often reported by customers. Run-time error 429, ActiveX component can't create object MSComm Running the available DEMO software on your serial ports will prove this instantly. SuperCom handles serial hardware the proper way while reading data. SuperCom does not have such problems or limitations.
