Error when closing

[SmickBones]

Hello, I am running grabserial to log moisture data from an Arduino on a Raspberry Pi.

The command that I run is as follows:

grabserial -d /dev/ttyACM0 -T -e 3600 -o "%Y-%m-%d.txt" -a -Q

This seems to work fine, logging the data to the file, (I know the length of time/timestamp doesn't make sense, I haven't finalized that) but when I press Ctrl+C I get the following error:

^CTraceback (most recent call last):
