You have a laptop set up as a portable serial terminal and all-around networking troubleshooting tool, so you need multiple connection profiles in Minicom to connect to different servers.
As root, set up a new Minicom configuration just like in the previous recipe. Then, instead of selecting "Save as dfl," select "Save as…" and type in the name of your choice, such as pyramid. Now, any user can use this configuration with this command:
$ minicom pyramidOrdinary users cannot change the serial port setup settings in Minicom, except for bits per second, and cannot save configurations.
