MllpReceive Tool
You can use the MllpReceive tool to receive data from an MLLP send port.
You install this tool through the BizTalk Accelerator for HL7 (BTAHL7) Custom installation procedure. If you performed a Typical installation to install BTAHL7, then you must run a Custom installation and install the test tools in order for this tutorial to work correctly. At the Custom Setup screen, select MLLP Test Tool from the Adapter folder, and select Test Instances from the Artifacts folder. For more information, see Performing a Custom Installation.

If you installed BTAHL7 through the default installation, and have not installed the MLLPTest tool (including MllpReceive and MllpSend), you will not be able to test your tutorial results.
