Rich,
I will type up my findings and post them. I hadn't had time to do that
in the last few days, and didn't have time to do it today either.
Set up a listener in Mirth as an LLP listener first.
Use OS telnet then %ZISTCP to test the connection from the OS and from
VistA respectively. This will establish that VistA can communicate
with Mirth using the specified port.
In MAS parameters, you need to set SEND PIMS HL7 2.3 MESSAGE to START
and SEND PIMS HL7 2.2 MESSAGE to STOP (the latter uses other
protocols... I didn't investigate it).
If you are using WorldVistA, there's a bug in Registering a patient in
the CIRN/MPI code. Once you find the line that crashes, you can
comment it out, or you can wait for my patch. Or you can disable the
CIRN HL7 message (more on that later).
In HL7 Main Menu, go to interface developer options, and either make a
new Logical Link going to Mirth or hijack one that already exists (I
did both... hijack VAFC-SEND for ease...). Change the link type to TCP
and put the ip and port where Mirth is listening.
In HL7 Main Menu, go to interface developer options, and edit protocol
VAFC ADT-A04 SERVER.
Here you have two options. You can create a subscriber protocol or
hijack the CIRN subscriber protocol... since you may want to disable
the CIRN message anyways (from above), you could hijack the CIRN
protocol RG ADT-A04 TRIGGER
Add the logical link to the protocol you designed or the hijacked protocol.
MAKE SURE TO DELETE any values for Routing Logic. That was the reason
that the message didn't work all along and I only discovered it after
arduous stepping through code. Also recommended to delete Processing
RTN values.
In HL7, make sure you started Task Manger, start TCP/IP Link Manager,
then start your logical link.
Register a patient, and you should see an HL7 message go through.
