Asynchronous Driver Support for EPICS
EPICS (Experimental Physics and Industrial Control System) is a toolchain allowing the user to create a professional control system infrastructure. EPICS is developed by the Argonne National Laboratory located in Lemont, Illinois, USA, the Berliner Elektronenspeicherring-Gesellschaft für Synchrotonstrahlung mbH (BESSY) from Germany and others.
It is licensed as open source software under the EPICS Open License (http://aps.anl.gov/epics/license/open.php) which is very similar to the BSD license but contains some additional privileges for the US government funding the work on the project.
This "asyn" driver package is an extension to EPICS Base that provides a facility to use asynchronous input and output from EPICS IOCs.
