notes: |
The directive may be used to print debug and test information. It uses
${putc:/name} to output the characters. This directive performs a character
translation from ``NL`` to ``CR`` followed by ``NR``.
If the kernel character output device is concurrently accessed, then
interleaved output may occur.
