Hello forum,

I am a embedded developer new to web development. This is my first post here !
I designed a simple website with html and php. Now I will configure it to send some data to client as a file.
There will be an application at client which will transfer this file to other board via UART interface. Now at this point, user has to download the file and use it with the application to get job done.

My question is, Can we invoke client side application (command line executable) to automate it somehow ??
taking permission from user at first time is fine.

I came across 'ActiveX' but can't use it since both server and client are on Linux platform. Any easy way out?
