+You can check whether the sessions exist with `tmux ls`.
+This is the command to connect to the serial interface of the FM using the
+RS422 interface of the flight preparation panel:
 
 ```sh
-tmux a -t q7s-serial
+tmux a -t q7s-fm-fpp

 If the session does not exist, you can create it like this
 
 ```sh
-tmux new -s q7s-serial
-/bin/bash
-q7s_serial
+tmux new -s q7s-fm-fpp -t /bin/bash

-## Port forwarding for connection to TCF agent
-
-This is a required step to connect to the `tcf-agent` on the Q7S, which is required for convenient
-remote debugging. Assuming the IPv6
-
-```sh
-ssh -L 1534:192.168.133.10:1534 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t /bin/bash
-```
-
-You then need to connect to `localhost` with port `1534`.

-## Port forwarding for file transfers with `scp`
-
-```sh
-ssh -L 1535:192.168.133.10:22 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t /bin/bash
-```
-
-You then need to run `scp` with the `-P 1535` flag with `localhost` as the target IP address.

-## Port forwarding for TMTC commanding
-
-You can enable port forwarding for TMTC commanding with the following command:
-
-```sh
-ssh -L 1536:192.168.133.10:7301 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t /bin/bash
-```
-
-This forwards TMTC packets on port `1536` of localhost to the TMTC reception port of the Q7S.
-
 ## Set up all port forwarding at once
 
+Port forwarding is necessary for remote-debugging using the `tcf-agent`, copying files
+with `scp` & `q7s-cp.py` and sending TMTC commands.
 You can specify the `-L` option multiple times to set up all port forwarding at once.
