Creating a new portable package from scratch that provides those parts 
of AsyncPro's user program API you need would be great. Same could be 
enhanced with additional features whenever necessary.

The primarily essential part of AsyncPro's basic functionality is the 
thread based buffer handling. By this the AsyncPro "Events" can be 
handled by the main Thread of the application and thus in an "even 
driven Object-Pascal" way, freeing the user from dealing with threads 

This now needs a portable "backend" of inter-thread notification. This 
can be done with messages (such as AsyncPro works).

Using the LCL "Windows", "KDE" or "Gnome" Widget set ,this can be done 
by PostMessage (SendMessage) and "Procedure ... Message". Unfortunately 
the non GUI-based Widget sets  ("NoGUI", "FPGUI", etc") don't seem to 
support this (yet) (no idea about Mac). I feel this is a big 
short-coming for "Using Lazarus on Embedded Linux". Maybe SyncOBJs can 
be used in a more portable way to achieve the same goal.
