I write code, and work with GUI's like this every day, for the same type of control. This is more modern than some stuff we use in the US.
Not only am I configuring new devices to communicate at 38,400kbs, I'm using a serial to RJ-12 connector to plug into them. There is newer software laid over for a GUI, but the backbone looks like its from Windows 3.1.
The controllers I use have less than 100MB of storage.
I work for a multi billion dollar company.
