-=====The Data Logger=====
+===== Untethered Re-Cording Mode =====
+Untethered Re-Cording mode was introduced in [[twiddler_firmware|Version 12]] of the Twiddler Firmware.  In this mode, the Twiddler can run headless and will record every HID code to an on-board data file.  When you connect the Twiddler to a host device, you can re-play all the HID codes to have them automatically entered into your program of choice.  There are utilities available, like [[https://github.com/CoohLand/Trout|Trout]] for Linux, that will directly read and parse the datafile from the command line.
+To enter untethered mode, just type [[chordnotation|N+S 00M0]].  Everything typed from this point forward will be logged to a file on the Twiddler's [[flashdisk|Flash Disk]].  To exit untethered mode, use the same chord [[chordnotation|N+S 00M0]].  **You MUST exit untethered mode before turning the power switch off to ensure the most recently typed data is saved and the flash disk is handled gracefully.** Failure to do so will cause loss of data and may corrupt the FAT file system.
+To retrieve the data, just connect the Twiddler to a host, open a word processor or other text entry program and type [[chordnotation|N+S 000M]].  The Twiddler will then begin to stream the contents of the datafile to your host as a stream of HID codes.
