HDLC, Creating server

Hi,
I have question about HDLC. You can choose framing as wrapper or HDLC. And there is HDLC as type of communication profile. Is it 2 different things or it's something similar?

I'm supposed to make an server app, which will be using HDLC instead of TCP/IP. So what I need to use? I guess not gurux.net, but gurux.serial?

Thanks

Hi,

Some meters are sending HDLC packets over TCP/IP. Using wrapper is more efficient in TCP/IP networks.
You can use HDLC for TCP/IP if you want to.

BR,
Mikko

Hi Mikko,
I'm trying to create server in java. I'm trying to understand and adapt your server examples.
And I have questions, if I can specify which authentication is used (low, high, high with sometnig). Also if server and client ID can be specified as well, and how can I do it. I tried something, but it didn't work.

Thanks

Hi,

The client decides (proposes) what authentication level is used. Not the server.
