Minicom won't start with incorrect def file

[RogerDavis]

I fumblefingered the serial port setup for Minicom, and now it ALWAYS finds the incorrect settings.

I can start as "sudo minicom -s" and enter the correct info, save it, it says it saved it, then retry and still get the wrong setup

I can remove the program, delete the configuration files (which don't disappear when the program is removed), reinstall the program, and it STILL finds the wrong serial port info!!!!!!!

How do I fix this?

1. Use Synaptic to remove the whole package, not just the program files.
2. Check your home folder for any relevant hidden files.

No luck, same result.

Complete removal with Synaptic, then removed the log file from my home folder.

Still says "minicom: cannot open /dev/ttACM0: No such file or directory"

I need to change this to "ttyACM0".

$ man minicom

-s Setup. Root edits the system-wide defaults in /etc/minirc.dfl

$ sudo rm /etc/minirc.dfl
$ sudo minicom -s

[RogerDavis]

Nope - before "saving" correction...
minicom: cannot open /dev/ttyACM0: Input/output error
roger@roger-desktop:~$ minicom
after "saving" correction...
minicom: cannot open /dev/ttACM0: No such file or directory
roger@roger-desktop:~$

[dcstar]

$ man minicom

-s Setup. Root edits the system-wide defaults in /etc/minirc.dfl

$ sudo rm /etc/minirc.dfl
$ sudo minicom -s

Running 12.04 minicom and saving new default settings creates a hidden .minirc.dfl file in the user's Home folder.

Unless this is manually deleted then the settings will not change:

rm ~/.minirc.dfl

[RogerDavis]

Results :
roger@roger-desktop:~$ rm ~/.minirc.dfl
rm: cannot remove `/home/roger/.minirc.dfl': No such file or directory
roger@roger-desktop:~$
roger@roger-desktop:~$ minicom
minicom: cannot open /dev/tty8: Permission denied
roger@roger-desktop:~$

And how did tty8 get into the picture? That's not what I had there.

Results :
roger@roger-desktop:~$ rm ~/.minirc.dfl
rm: cannot remove `/home/roger/.minirc.dfl': No such file or directory
roger@roger-desktop:~$
roger@roger-desktop:~$ minicom
minicom: cannot open /dev/tty8: Permission denied
roger@roger-desktop:~$

tty8 is the default on a new connection. This will allow you to change it:

sudo minicom

[HermanAB]

Anyhoo, the default settings file is called minirc.dfl, so you can hunt it down with find, and then blow it away with rm.

$ find / -name minirc.dfl

When minicom is restarted it will make a new one.
