Thank you for your answer maschoen. Yes, in general, I need simple messaging (date+time+short message, archive of the messages, visual alert for both guys) between Win machine and QNX4+Photon machine.
One way is let’s say standard - using some simple E-mail client - is there some E-mail client (with GUI) for QNX4+Photon 1.13 available?
This alternative would require the cooperation of the plant network admin and their E-mail provider - to ensure the QNX node access to their E-mail server. The disadvantage is that even if the simple client exists, it would be probably only in English.
The other way is to do this “inside” QNX4+Photon - because the remote Win machine runs Phindows connected to the “host” QNX4+Photon node (control room SCADA application).
We are thinking the way to make our task (with GUI) for reading+writing+sending the messages, automatic date+time appending while pressing the “Send” button and storing the date+time+messages in SQL database table (cyclic “buffer” of limited history).
As for the visual alerting we intend to use already existing alarm system of our SCADA - pressing the “Send” button may invoke some alarm alert (in “New Message” new alarm class).
But if we find better (more simple) way, it would be fine.
