Richard, I was most impressed by your answer below (in '03)
Do you know whether there is a third party application/library that can interface our software to the HL7 sockets systems so we do not have to develop them?
If you do, which one would you recommend? Thank you, [] Richard M.

Given that HL7 is really only sending and receiving some information in a curious format, and that you either receive data and then send the other side an ACK or a NAK, or wait until they do that in reply to your message, it is really not all that complicated. The short answer to you question ist Twisted - <http://www.twistedmatrix.com>http://www.twistedmatrix.com What may confuse you is that it does not use blocking sockets and therefore does not need to be multithreaded, although I think it can be, but it does work. My bread and butter Python work is software that interfaces between a Pathology System running any number of versions of Unix and some overarching Hospital System that provides me with patient data and to which I deliver reports and accounting data, mostly, but not always, in HL7. I have one Pathology Unit that does work for two hospitals and communicates with two hospital systems. With Twisted I basically subclass protocol.Factory and implement the necessary submethods. It is a little daunting at first and there was at the time (about 2 years ago) when no usable documentation worth speaking of was available. I am also stuck at the moment with Twisted 0.18.0, because it runs with Python 1.5.2, and I had trouble getting Python >= 2.0 running on the all the Unixes I had to get it running on. In the meantime, I think I've got that under control. If you're interested in looking at the programms I will have to ask the company I developed the software for, but the complete program is only ca. 800 Lines and covers 4 Low Level Protocols. I hope I have been of some help. Once people realise that what you want is some sort of select-loop-server, then they will probably gush forth with helpful suggestions.
