=== main
=== all
The following commands are available:

at		AT commands to the target
disable		Disable receiving and display of certain packet types
enable		Enable receiving and display of certain packet types
exit		Exit from fc-shell
poweroff	Send power-off ETM command packet to the target
quit		Alias for exit
send		Send arbitrary RVTMUX packet to the target
sp		Send GPF system primitive to the target
str		Send arbitrary strings to ATI
tch		TCH commands, see help tch
tch-dl		Enable/disable TCH downlink forwarding on the target
tgtreset	Send reset/reboot ETM command packet to the target

To get help on any command, type help and the command keyword.

=== at
=== AT
Any fc-shell command input that begins with the characters "at" or "AT" is sent
literally to the AT command interpreter (ATI) in the target firmware via the
FreeCalypso-defined "AT" RVTMUX channel.  Use the str command (see help str) to
send strings to ATI which do not begin with "at" or "AT", e.g., when sending
SMS.

Any time you send anything to ATI, fc-shell automatically performs the
equivalent of an enable ati command so you can see ATI's responses; any
asynchronous output from ATI is also enabled as a side effect.

=== disable
=== enable
{dis,en}able ati
{dis,en}able gpf
{dis,en}able tch

fc-shell is fully asynchronous: user commands cause RVTMUX packets to be sent
to the target, whereas incoming packets from the target whose reception and
display is enabled are decoded and displayed.  The disable and enable commands
tell fc-shell to disable or enable receiving and display of the specified
packet types (RVTMUX channels); multiple channels may be listed in a single
command.

=== exit
=== quit
This command is self-explanatory.

=== poweroff
This command sends a power-off request in the form of an ETM ABB register write
command packet to the target.

=== send
send xx xx xx xx...

This command sends an arbitrary RVTMUX packet to the target, given as raw
hex bytes.

=== sp
sp <dest> <command>

This command sends a GPF system primitive to the target.  The first blank-
delimited word after the sp command keyword is the protocol stack destination
to which the sysprim is to be sent, and the rest of the string is passed
literally to the target.

This command also automatically performs an equivalent of enable gpf so you can
see the response to your sysprim; you may later need to issue a disable gpf
command to stop the occasional asynchronous noise that may be emitted on the
GPF RVTMUX channel by various G23M components.

=== str
str <arbitrary text>

This command sends everything after the str command keyword to the AT command
interpreter (ATI) in the target firmware via the FreeCalypso-defined "AT"
RVTMUX channel.  This command can be used to send strings to ATI which do not
begin with "at" or "AT", as may be needed when sending SMS.

Any time you send anything to ATI, fc-shell automatically performs the
equivalent of an enable ati command so you can see ATI's responses; any
asynchronous output from ATI is also enabled as a side effect.

=== tch
=== TCH
The commands in this set exercise the experimental TCH rerouting feature
implemented in some FreeCalypso GSM firmware versions; these commands have any
effect only when run against one of these specially built fw versions.
The available commands are:

tch dump-raw	Enable or disable the raw dump mode
tch play	Play a file into TCH uplink
tch record	Record TCH downlink in a file
tch status	Show current status of TCH operations

Type help tch <subcmd> to get the detailed description of each of these tch
subcommands.

=== tch:dump-raw
tch dump-raw on|off

This command tells fc-shell what it should do with incoming packets on the
RVTMUX TCH multiplex channel.  If the raw dump mode is off (the default),
fc-shell processes these incoming packets intelligently; if the raw dump mode
is on, fc-shell dumps these packets in raw hex and does nothing more, presenting
the behaviour it had before tch play and tch record commands were implemented.
tch play and tch record cannot be used when the raw dump mode is enabled.

=== tch:play
tch play <filename>	# start TCH UL play
tch play stop		# stop TCH UL play before the end of the UL play file

Please refer to the doc/TCH-bit-access article in the FreeCalypso host tools
source for the details.

=== tch:record
tch record <filename>	# start TCH DL recording
tch record stop		# stop TCH DL recording

Please refer to the doc/TCH-bit-access article in the FreeCalypso host tools
source for the details.

=== tch:status
This command shows the current status of tch record (running or not running),
the current status of tch play (running or not running, outstanding uplink
frame count) and the current state of the raw dump mode (enabled or disabled).

=== tch-dl
tch-dl on|off

This command sends a TCH_CONFIG_REQ packet to the target, requesting that TCH
downlink forwarding be enabled or disabled.  You typically don't need to issue
this command explicitly when you use the higher level tch record functionality,
but it is available nonetheless.

=== tgtreset
This command sends a reset/reboot request ETM command packet to the target.
