that makes sense - as active x is (as far as I am aware) depreciated in all 
browsers newer then IE 11

maybe it is using ActiveX

https://en.wikipedia.org/wiki/ActiveX

the script could be invoking another OCX component that does the actual heavy 
lifting. just a guess.

Re: Communicating with external electronics

Hi Keisuke,
There is a current system, it is slow, it requires weird interfacing between 
(yes!) IE11 and Edge 
- scanning a QR code from the screen (IE 11) to lookup(?) data used in a sql(?) 
system displaying in EDGE

IE11 runs the existing scripts using JAVA, and some (specialized?) web tools 
installed on the device
I was told that they had tried to use a modern browser (Edge, Firefox etc) but 
the scripts error-ed out.

The scripts, and (as far as I can tell) all the software is in-house and 
proprietary.

Re: Communicating with external electronics

[Keisuke Miyako via 4D_Tech]

I suppose the scripts are written in Python or some other language.

the script language is probably not important. 
I imagine it is published as a "language neutral" sample code,
not as a Software Development Kit or middleware.

you might even be able to translate it to native 4D for HTTP or RS-232C, 
NTK for TCP, UDP, etc. 
I would not recommend Internet Commands for new development.

it is more important to know the communication protocol for the device.

Communicating with external electronics

[nug via 4D_Tech]

I might have a an opening for a project..
I would need to be able to communicate (from windows 10) to an external 
electronic board.
running 'scripts' (do not know if the scripts will exist (LEP) or will need to 
be written (4D).

I would need to run these scripts, to run tests on another piece of electronics

4D --> board --> electronic device
device --> return results of tests to board --> to 4D

I have not done this type of device manipulation in the past.

Anyone here?

if so - what would I be getting myself into?

Thanks
Chip
