The HL7 Listener is a utility which functions like a simple
HL7 server. It is designed to make
it easy to listen and record a stream of messages from an HL7
server. It is a single form application which comes free with
Chameleon, and can be accessed from the iNTERFACEWARE programs menu.
The most powerful feature of the listener is that the
log file can be replayed through the HL7 Simulator
tool to recreate the original HL7 feed for development and testing.
