I'm usually of opinion that if I have a tool already, whether built-in or really fitting my workflows, I prefer it to another app or tool I would have to get - even if it would improve my quality of life.
That's why I don't install any nice gui serial apps and use screen:
1ls -la /dev/tty | grep tty
2screen /dev/tty.whatever 9600
I also always forget the specifics, hence this post.
