commit dee3df68ab4b00fff6bdf9fc39541729af37307c upstream. According to the VT220 specification the possible character combinations sent on RETURN are only CR or CRLF [0]. The Return key sends either a CR character (0/13) or a CR character (0/13) and an LF character (0/10), depending on the set/reset state of line feed/new line mode (LNM). The sclp/vt220 driver however uses LFCR. This can confuse tools, for example the kunit runner.
