Still Working Toward SPOCS 2.0

Augh.  I thought the Modbus problem was fixed a night or two ago.  The problem stayed away for two hours, then reappeared early the next morning!  Sometimes that female Festival voice sounds a little snippy when she says "warning, warning, node 11 slot 4 is down", followed immediately by "Attention, node 11 slot 4 is operating".  It typically shows up about every 20 minutes, and only on the one Modbus node that is reading 16 registers (instead of 1).  Oh, well, back to it...
