Recently upgrade my RPi 4 -> 5.
Decided to move from cqrlog 2.5.2 to "latest": Version Alpha_(137)_

After fixing dependencies, building went smooth and as expected.
I like all new functionality, and I can appreciate all the good work that has gone into this!!!

Detail that is not working: CW interface to my K3NG keyer which is used for both configured radios (FT991/FTDX10).

I wonder if this is related to configuration, as logging seems to miss some details?
My configured port for the K3NG keyer is /dev/ttyACM0 (115200 8N1), but that seems not been used?

I hope someone can give me some pointers/advise as how to approach this issue.
