+  <b>Synopsis</b>.
+  This command can be used to dump (and clear) the content of any buffered syslog output messages.
+  This command is only available if <code>CONFIG_RAMLOG_SYSLOG</code> is enabled.
+  In that case, syslog output will be collected in an in-memory, circular buffer.
+  Entering the <code>dmesg</code> command will dump the content of that in-memory, circular buffer to the NSH console output.
+  <code>dmesg</code> has the side effect of clearing the buffered data so that entering <code>dmesg</code> again will show only newly buffered data.
