asynDriver (also called Asyn) is a general purpose facility for interfacing device specific code to low level communication drivers. A primary target for asynDriver is for EPICS IOC device support, but other than using the EPICS build system and libCom library, most of the code was designed so it can be used outside of an EPICS IOC.

At the time (~2006) this module did not support setting but only reading and this was the impetus for NSCL to develop its own EPICS device support module based loosely on the DESY code. Another EPICS SNMP device support module developed by Sheng Peng, which also adds setting support, is available here. Requirements NET-SNMP

The following tables document the asyn interfaces used by the EPICS device support. The drvUser parameter is used by the driver to determine what command is being sent from device support. The default is MODBUS_DATA, which is thus optional in the link specification in device support.
