``serloop`` Serial Loopback
|
||
===========================
|
||
|
||
This is a mindlessly simple loopback test on the console. Useful for testing new
|
||
serial drivers. Configuration options include:
|
||
|
||
- ``CONFIG_EXAMPLES_SERLOOP_BUFIO`` – Use C buffered I/O (``getchar``/``putchar``) vs.
|
||
raw console I/O (read/write).
