Experimental Physics and Industrial Control System

I am writing device support for a message-based VXI module that
supports two modes of data transfer:
(1) Via a message, specifically through the SCPI "TRACE #" command.
This is too slow -- 1000 words takes 30 seconds.
(2) Via shared memory, using the SCPI "SMEM" command. The
documentation shows an example using the VISA viMoveAsync routine,
but I believe there is no VISA library for EPICS.
Can anyone give me pointers on writing a routine using shared memory
transfer? The VXI slot-0 controller is a hkbaja60 module.
