'minicom throwing an error minicom: cannot open /dev/modem: No such file or directory
I have tried to connect my Jetson Nano with TTL UART cable using minicom. When I typed
sudo minicom
It showed an error
minicom throwing an error minicom: cannot open /dev/modem: No such file or directory
Solution 1:[1]
Later I tried with
sudo minicom -s
It worked
Solution 2:[2]
sudo is always a way...
What minicom tells you with this message that it has tried to open a interface called /dev/modem. It is telling you, that it can't be opened due to insufficient permissions.
On my system /dev/modem does not even exist! Anyhow, minicom expects in it's settings the /dev/modem as default. That's why it's trying to connect to that.
So, the solution is minicom -s, where you actually enter the settings of minicom. Her you'll find the the settings to properly configure your board. If you run this with sudo, you are able to also save your settings, if you want to. You might want to change those settings to e.g. /dev/ttyUSB0 or something.
