Serial Console Issues or Delays on Linux
If you're on Linux, and are seeing multi-second delays connecting to the serial
console, or are seeing "AT" and other gibberish when you connect, then the
modemmanager service might be interfering. Just remove it; it doesn't have much use
unless you're still using dial-up modems.
To remove modemmanager , type the following command at a shell:
sudo apt purge modemmanager
Setting Permissions on Linux
On Linux, if you see an error box something like the one below when you press the S
erial button, you need to add yourself to a user group to have permission to connect
to the serial console.
On Ubuntu and Debian, add yourself to the dialout group by doing:
sudo adduser $USER dialout
After running the command above, reboot your machine to gain access to the group.
On other Linux distributions, the group you need may be different. See the Advanced
Serial Console on Linux()for details on how to add yourself to the right group.
Using Something Else?
If you're not using Mu to edit, are using or if for some reason you are not a fan of its
built in serial console, you can run the serial console from a separate program.
