Experimental Physics and Industrial Control System

Iff the interface is strictly HTML, then it can be do-able using
streamDevice, but it can be tricky, too. If the device has layers of
pages to get through before the data of interest is available, then it
gets very difficult. I did this with a simple device once, and it worked
fairly well. When we purchased another ostensibly identical device, it
failed, and I never got it working because the 'HTML' data was sent
using Javascript that drew dots like a dot matrix display on the web
page, so it would look like one of those 4 line X 20 character LCDs that
was one the physical front panel of the device.

It says that communication is done with the HTTP protocol - is this
significant? Would it be doable for me to make an IOC that uses let’s
say StreamDevice to communicate with this?
