 Originaly osFree PM was taken from FreePM project by Evgeny Kotsuba. Since last update by Evgen  many time is gone. So we forked FreePM project. We still name it as FreePM, but, if Evgen will continue to work with it's original project, we'll need to rename it. Originaly osFree PM was taken from FreePM project by Evgeny Kotsuba.

The communication between the server and the client goes through a named pipe with a certain [[en:docs:pm:pm_protocol|protocol]]. Such as a command token (opcode) and following data.
  
-The core part of the server is in “FreePM/src_s/Fs_main.cpp” in the function “Fs_ClientWork”. There is quite a bit with code which deals with synchronization, Evgen has done a lot of work with that part. +The core part of the server is in “FreePM/src_s/Fs_main.cpp” in the function “Fs_ClientWork”.

-The PMDRIVER.DLL driver creates a PM window (with some graphics art) and monitors the messages it gets from that.
