Unfortunately, SPOCS is not the central thing in our lives. Work, family, etc., etc. all take their share of our time. by the way, the SourceForge page is http://sourceforge.net/projects/spocs/.
There, you can get your mitts on SPOCS version 1.x. It only has the Optomux serial & modem drivers, whereas the new SPOCS 2.0 has Optomux, ASCII, and Modbus serial drivers.
The Modbus reads & writes work great! Just a few more things to nail down...
