sorry i dont understand what is wrong with that what i say?!
Again and Again and Again....
I have to use ROS so how can I do it with an CB? And which CB is sensitive?
I know I'll probably regret this.....
This is how I (and I believe others) are interpreting this thread:
1. You are in Austria, where rules allowing APRS and other Packet are allowed on CB frequencies.
2. Originally it appeared that you were in a house and you wished to place the radio in the attic, but you were unable for some reason to run cables to the attic. You have since clarified that you are in a multi unit occupancy, and the "attic" is where all service comes into the building. In the US, this would probably be referred to as a penthouse or elevator service room.
I would have serious security concerns placing any radio in a common area
3. You have never fully clarified what actual
control you want to have over the radio. Is it just TX/RX of the packet data, or are you looking for full control of the radio, such as changing channels, modes and controlling the squelch and clarifier? This question is probably the largest point of confusion.
What type of LAN access do you have in the server room? Can a computer in your apartment see the other computers on the LAN, or is there a firewall in each apartment that prohibits this? If you can plug a computer into the LAN in the server room and see it, the whole issue gets a
little easier (security issues aside.)
4. You have provided links to some really questionable sources. You must understand that the video posted by the person using 2 CBs for packet appears pretty cheesy.

We understand what you are trying to do, but you must understand that we are working on theory, as none of this is allowed where we are. Is it possible? Yes. Have we done it? No. The first way of working through it is to make suggestions and let others give reasons it won't work, then analyze those reasons and determine if they are valid. If they are, workarounds have to be floated in the same manner. It may seem negative, but by answering our questions as completely as possible without getting frustrated, you give us the best chance of devising a solution for you.
If you are looking for data only without control of radio functions beyond TX/RX, and can access the remote computer over the building's LAN I do not see why a TNC wouldn't do exactly what you're looking for. Mic pinouts are readily available and you would probably have to make your own interface cable, but that really isn't that hard. The system
will not work without an intermediary device (the TNC.) You cannot just hook a computer directly to the radio. If you are looking for full control, there are links to an interface, and that is where the DB-25 cable becomes necessary.
I understand you're frustrated, but so are we.
