Experimental Physics and
Industrial Control System

Richard,
I'm using Modbus in RTU mode over serial.  The 1998-vintage
driver was provided by Bob Dalesio, he may have the latest
source.  I can send you my source, otherwise.  The driver is
written for an out-of-production Motorola MVME335 module.
Around 1998 the board was being manufactured by legacy
supplier GD California. I'm running the driver on the
MVME177 CPU.
