This is not as simple. ttyS1 is the the console name and ttysclp0 is the tty name.
This has mostly historic reasons and it obviously causes problems.
But there is documentation out that that actually describes the use of
console=ttyS1 console=ttyS0.
to have console output on both sclp consoles and there are probably scripts
using ttyS1.
I am wondering. The tty for ttyS0 is named sclp_line0. Does this work in LPAR?
