Through the ActiveX interface, you can pre-populate your Send dropdowns with string by applying the “AddCannedString” function “AddCannedString” feature. You can include a variety in CRCs, as well as Checksums to the end of the string you send. Look up the datasheet of the BL233Bchip that is used, where the commands are described.
You are able to utilize Windows remote DCOM for stop, start and manage remote Realterm as well as Local copy. If the connection is damaged or the buffers have become filled because of reasons, it stops trying to echo characters.īe aware that Realterm is a fully ActiveX interface.

COM port numbers should only be used with COM names.īy default, the combined operation of the class installer for the Ports device setup class and the Serial function driver configure a device as a COM port.įor information about how the Ports class installer and Serial function driver create a COM port device interface for a COM port, see External naming of COM ports.Capture as Hex, i.e. If you use a COM name, you must obtain the COM port number from the COM port database. To ensure compatibility with most applications that access COM ports, you should assign a symbolic link name that uses the standard naming convention COM, where is the COM port number (for example, COM1).
You operate the COM port by using the 16550 UART-compatible interface that is defined in Ntddser.h. The GUID for this class is GUID_DEVINTERFACE_COMPORT, which is defined in Ntddser.h. You access the COM port through an instance of the COM port device interface class. A COM port is a type of serial port that complies with the following additional requirements:
