Gpredict and rotator control

Gpredict
1

Hello,
I am trying to build my own ground station.
Before start building hardware staff, I would like to test gpredict and how communication works.
I setup an ubuntu pc, with gpredict and hamlib.

I create virtual ports using the following command:
socat -d -d pty,rawer,echo=0 pty,rawer,echo=0

which creates the ports /dev/pts/1 and /dev/pts/2

next I give the command:
sudo rotctld -m 202 -r /dev/pts/1 -s 9600 -T 192.168.79.12 -t 4533 -C timeout=5000 -C retry=0 -vvvvvvvv

and seems that something is waiting for and after that I go to gpredict, and track satellite using the antenna rotator. but I cannot see any message in the terminal.

I sure that I setup something wrong, but can anyone give me a hint?

Thanks in advance.

Do you want to emulate a rotator ?
In that case, start rotctld with model 1 (dummy), no ports required.
rotctld -m 1 -t 4533 -vvvvvvvv
and then in another terminal, try it with rotctl -m 2 -r localhost:4533 or with gpredict.
