Multi-server is required.  The HIS (Meditech) can open multiple connections at once to send out the query message.  

The HIS does not get an ACK back from the interface engine when the query message is received as the ACK needs to contain the results of the query so the reply message from Passport is the ACK and Message in one.

Sample reply message from Passport going to Meditech

If I have it set up as server and not multi-server it will work but if another registration happens on Meditech, the user gets a message back (on Meditech) that the server is busy when it tries to query Passport.

My thought was to try to set the DRIVERCTL values in the MSH.10 on the message out to passport.  When Passport responds I can use the information in the MSH10 to route the message to the proper connection on the multi-server thread.  Have not tested yet but that is the way I will continue unless I hear of a different way.

There are a couple of factors that need to be taken into consideration.  The system it’s coming from – what font does it use fixed or proportional.  The data in the entry does not line up, so I assume it would be proportional.  The other factor is where the data is going to – is it proportional or fixed fonts?

If fixed for the destination, do the following steps:

1. Break down into lines like what you currently do

2. Take each line and break it down to a list by each data element (two or more spaces)

3. Join the lines back together after fixing each element in the list to a specific length (column width)

If proportional – you can do a similar method but would need to add in coding to accumulate the width of each character.
