Can anyone tell me if there is a serious terminal program for android
phones?

I mean a full OS and the basic commands.  Especially I'd like to have
ssh and scp among them.

What I've already tried and found lacking:

Terminux
simple sshd
ConnectBot
Material Terminal (Supposed to be an improvement over Terminal
          Emulator  for Android so didn't try that one)
