Where does the file name come from? Do you ask the user? Is it
requested by the remote client?

There is an introduction to socket programming here:
http://www.amk.ca/python/howto/sockets/

Did you look at the links I posted? The NetEpi project seems to have a
complete implementation of an MLLP listener. It uses another project
called halftwist that I can't find but it may still be helpful. The
Mirth link also looks promising.

This page seems to have a good description of the MLLP protocol:
http://www.hl7.org/v3ballot/html/infrastructure/transport/transport-mllp.htm

I don't know your experience level, but if you can't understand the
above MLLP protocol document you are probably in over your head.
