Dealing with Odd Systems

The simulator can also be used to deal with odd systems which do not follow the standard HL7 practice of ACKnowledging on the same port as the sender. These systems expect to be able to send their ACKnowledgement messages back to the sender on another socket that the sender is listening to.

By selecting Receive ACKnowledgement Messages via Server Socket, the Simulator can be configured to expect the ACK messages to come back via the port number specified in the box below. This is quite unusual and should not be necessary for most users.
