5 measurements are now performed during a 51 multiframe. They are performed
at one of the 5 FCCH.
Additionally a timeslot offset can be given for each measurement. This way
it is possible to measure each timeslot seperately. The given ARFCN must be in
sync with the serving cell.
By pressing '*', the analyzer is turned on or off.
Each beep indicated a new measurement result.
Right and left button can be used to scroll. By holding the button, the input
is repeated.
This app is used to measure receive level of given channels.
By pressing digits, the channel can be selected.
By pressing left or right button, the frequency is increased/decreased.
By pressing the menu button, the maximum received level is shown until
pressing menu button again. (usefull for hopping)
By pressing up or down button, the volume of a tone is changed, that
indicates rx level.
The left soft button is used to toggle PCS/DCS on shared channel numbers.
The right soft button is used to toggle uplink and downlink.
This application had already been removed a while ago, but
was added again with one of the initial framebuffer commits.

We revert the initialization of the palette to the behaviour of the
old non-fb driver.

Basically, there were two commands in an "else" block without brackets,
causing the
"end = 1023+299"
command to execute regardless of the state of index.

Power measurement returned the first measurement result twice, now it is
returned only once.
Wrapping of ARFCN allows to measure the E-band en block. After measuring the
ARFCN 1023, the ARFCN wraps to 0. Special flags like ARFCN_UPLINK or
ARFCN_PCS are preserved while wrapping.
In order to allow applications to use the power button, the keypad handler
will wait half a second if the key is pressed and hold, until the power
is turned off. This way the application does not need to handle it.
The power off function will then wait until the button is released, so the
phone will not start again while the button is still pressed.
This way we can independentely control what frequency we want and
wheter we want to TX or RX. This allow TX on DL band and RX on UL band.
This also means all call to tx_window setup now need to properly set the
ARFCN_UPLINK flag !

If a sequence error is received, the N(R) variable must still be used to
acknowledge previously transmitted frames.
If there are two subsequent sequence errors received, ignore it. (Ignore
every second subsequent error.) This happens if our reply with the REJ is
too slow, so the remote gets a T200 timeout and sends another frame with
a sequence error. Test showed that replying with two subsequent REJ
messages could the remote L2 process to abort. Replying too slow shouldn't
happen, but may happen over serial link between BB and LAPD.

Test showed that loosing the signal in dedicated mode caused a complete
rescann of all cells. By keeping the cell selected, the process can use
the neighbour cell informations to do a quick search for the best cell
afterwards.
This is testing the establishment of two ends (BTS, MS) one is in
the polling mode as used by osmo-bts. Transfer data between the two
ends. The sent data is not verified though. This should be followed
up soon.
