New line but no carriage return

[CvRXX]

hwlib/library/hwlib-ostream.hpp

Line 27 in a8db26e

constexpr char endl = '\n';

The \n in the above line does not do a carriage return in most Linux serial viewers. I think an \r should be added but then it's not a single char anymore.

from https://www.cplusplus.com/reference/ostream/endl/ :

Its behavior is equivalent to calling os.put('\n') (or os.put(os.widen('\n')) for character types other than char), and then os.flush().

Currently the ostream is not buffered, so the flush part can be ignored.

The real problem is that '\n' is supposed to send or , depending on the conventions of the host, that is, the platform the code is running on. So there is no obligation to do either way.
