No, no, that is not Frankenstein's monster running amok around the countryside.  It's just me, stomping out bugs in SPOCS version 2.2.
The new DR1 driver (Optomux, RS-232/485) is working great.  The new DR2 driver (temperature, RS-232) had a couple bugs, but it is now well.  DR3 (Modbus serial, RS-232/485) is running, but has a bug or two remaining.  The semaphore system that allows DR1 and DR3 to share the same RS-485 network is working very well.  I also added two more serial ports to the development machine, to make work easier.  I used the Ultra two-port board, sold by Tiger Direct.  It goes for less than $10, but DO NOT use the installer that comes with it.  Go to the Ultra website, and get the newer one.  It works like the proverbial charm.
After I get DR3 debugged, it will be time to work with the USB to serial drivers.  I am looking forward to that.
