./bin/native/default.elf -d
-Use UART redirection if you want to use a shell or get stderr/stdout
-output with/from a daemonized process.
-
-
-UART Redirection
-================
-
-You can redirect the processes' stdin/stdout/stderr by specifying
-one or more options from below.
-
-UNIX socket
------------
-
-To redirect stdio to a UNIX socket run:
-
- ./bin/native/default.elf -u -d
- RIOT pid: 18663
-
-Attach this UNIX socket:
-
- nc -U /tmp/riot.tty.18663
-
-TCP socket
-----------
-To redirect stdio to a TCP socket:
-
- ./bin/native/default.elf -t 4711 -d
- RIOT pid: 18663
-
-Attach this TCP socket:
-
- nc localhost 4711
-
-Stop the process:
-
- kill 18663
-
-File for stderr
----------------
-To redirect stderr to a file:
-
- ./bin/native/default.elf -d -e
- RIOT pid: 18663
-
-Read from it:
-
- tail -f /tmp/riot.stderr.18663
-
-File for stdout
----------------
-To redirect stdout to a file:
-
- ./bin/native/default.elf -d -o
- RIOT pid: 18663
-
-Read from it:
-
- tail -f /tmp/riot.stdout.18663
-
-
-Notes
------
-The stdout redirection only writes to file while no socket connection
-is established.
-
-Socket redirection is only available when the UART module has been
-compiled in.
-
-
