not have any knowledge of how the device is connected to the computer. Thus it does not
expose the transport protocol to the application. We are using HTTP protocol with XML to
communicate with the device. The MTXMLMCR.dll uses wininet.dll to talk to internet
protocols. The MTXMLMCR.dll. provides functions to convert the scan request into XML
format using msxml4.dll and then send it to the device using wininet.dll. It also provides
functions to convert the response from the device (XML format) to key/value pairs.
msxml4.dll : Microsoft XML Parser. MTXMLMCR.dll.

the msxml4.dll to convert the XML data back to key/ value pair.
