Hi. I am working for a broadcast company. And i realised that we are using many kind of devices such as satellite recievers (both home type and industrial type), signal decoders, regular switches and routers and many more which even i dont know what they do. long story short, i wonder is there a universal way to connect them and run commands on them? For example if i see an rs232 connection interface, should i think, yes i can connect it and run every commands to manipulate main operations which that device supports. Or if i see an ethernet input, should i say , yes this device supports snmp protocol. Generally what operating system do these devices have? Do generally companies produce their own softwares? When i typed 172.30.... and went to management console of that device via browser, what kind of a web server run? I searched for some devices manuals, they say it supports rs232 or snpm but i have never seen a command list about them. For example, how to find commands of a brand new but weird device let say an audio processor which has an rs232 interface.
What I have tried:
Not much until now. I read some manuals of devices and tried to find common similarities.
