@enumerate
@item fc-e1decode: Decodes a binary Melody E1 file into an ASCII source file.
@item fc-e1gen: Encodes an ASCII Melody E1 file into a binary Melody E1 file.
@item fc-fr2tch: Converts a GSM 06.10 speech recording from libgsm to hex
strings of TCH bits to be fed to the GSM 05.03 channel encoder of a TI
Calypso GSM device.
@item fc-tch2fr: Converts hex strings of TCH bits to libgsm.
@item fc-gsm2vm: utility converts a GSM 06.10 speech sample from the libgsm
source format into a voice memo file that can be uploaded into the FFS of a
FreeCalypso device and played with the audio_vm_play_start() API or the
AT@@VMP command that invokes the latter.
@item fc-rgbconv: Convers RGB 5:6:5 to RGB 8:8:8 and vice versa.
@item rvinterf: Communicates with a TI Calypso GSM device via RVTMUX.
@item rvtdump: produces a human-readable dump of all output emitted by a
TI-based GSM fw on the RVTMUX binary packet interface.
@item fc-shell: FreeCalypso firmwares have a feature of our own invention
(not present in any pre-existing ones) to accept AT commands over the RVTMUX
interface.  It is useful when no second UART is available for a dedicated
standard AT command interface.  fc-shell is the tool that allows you to send
AT commands to the firmware in this manner.
@item fc-memdump: Captures a memory dump from a GSM device.
@item fc-serterm: Trivial serial terminal.  Escapes binary chars.
@item fc-fsio: Going through rvinterf, this tool connects to GSM devices and
allows you to manipulate the device's flash file system.
@item tiaud-compile: Compiles an audio mode configuration table for TI's
Audio Service from our own ASCII source format into the binary format for
uploading into FreeCalypso GSM device FFS with fc-fsio.
@item tiaud-decomp: Decodes TI's audio mode configuration files read out of
FFS into our own ASCII format.
@item tiaud-mkvol: Generates the *.vol binary files which need to accompany
the main *.cfg ones.
@item fc-compalram: Allows running programs on the device without writing
them to flash storage.
@item fc-xram: Allows running programs on the device without writing them
to flash storage.
@item fc-iram: Allows running programs on the device without writing them
to flash storage.
@item fc-loadtool: Writes programs to the device's flash storage.
@item pirffs: Allows listing and extracting FFS content captured as a raw
flash image from Pirelli phones.
@item mokoffs: Allows listing and extracting FFS content captured as a raw
flash image from OpenMoko phones.
@item tiffs: Allows listing and extracting FFS content captured as a raw
flash image from TI phones.
@item c139explore: Run-from-RAM program for C139 phones that
exercises their peripheral hardware: LCD, keypad backlight, buzzer, vibrator.
@item pirexplore: Run-from-RAM program for Pirelli DP-L10 phones that
exercises their peripheral hardware, primarily their LCD.
@item tfc139: Breaks into Mot C1xx phones via shellcode injection, allowing
you to reflash locked phones with new firmware with fc-loadtool.
@item ctracedec: GSM firmwares built in TI's Windows environment have a
compressed trace misfeature whereby many of the ASCII strings
in debug trace messages get replaced with numeric indices at
build time, and these numeric indices are all that gets emitted
on the RVTMUX serial channel.  This tools decodes these numeric indices
back to strings in trace output.
@item fc-cal2text: This utility takes a dump of TI's /gsm/rf flash file system
directory subtree as input (either extracted in vitro with tiffs
or read out in vivo with fc-fsio) and converts all RF tables
found therein into a readable ASCII format.
@item imei-luhn: Computes or verifies the Luhn check digit of an IMEI number.
@item fc-dspapidump: Reads and dumps the contents of the DSP API RAM in a
target Calypso GSM device.
@item fc-vm2hex: Converts the old-fashioned (non-AMR) voice memo files read
out of FFS into hex strings.
@item fc-buzplay: Plays piezoelectic buzzer melodies on an actual
Calypso device equipped with such a buzzer (Mot C1xx, TI's D-Sample board,
our planned future HSMBP) by loading a buzplayer agent onto the target and
feeding melodies to be played to it.
@item fc-tmsh: TI-based GSM firmwares provide a rich set of Test Mode commands
that can be issued through the RVTMUX (debug trace) serial channel.
This program is our test mode shell for sending Test Mode commands to targets
and displaying decoded target responses.
@item fcup-smsend: Send a short message via SMS
@item fcup-smsendmult: Send multiple short messages via SMS in one go
@item fcup-smsendpdu: Send multiple short messages given in PDU format via SMS
@item sms-pdu-decode: Decode PDU format messages
