This switch allows you to change the name and location of the HL7 Listener failed messages log. By default, the log is named hl7failedmessages.txt, and it is written to the root of the C drive on the server where the HL7 Listener is running.
Type the command line switch -HL7FAILEDMESSAGES="pathname"(where pathname contains a full UNC path, including the file name and extension) for the location where you want an HL7 Listener failed messages log to be stored.
