wm6-utils/timer-adjust.py

# timer-adjust.py version 1.1, Silas S. Brown 2011, Public Domain, no warranty

# Requires Python to be installed on the phone (see Gradint page).
# This is Python 2 code; Python 3 was not available for WM phones.

# This is a Python script to adjust the built-in outgoing call timer
# on no-touchscreen Windows Mobile phones, configure the
# "wm6minutecount" program on with-touchscreen WM6 phones, or
# log signal strength on WM phones.

# No-touchscreen phones have an outgoing calls timer which can be
# reset to 0, but this script allows you to set it to any value you
# like, for example if you made a free call that you don't want to be
# counted, or if you made extra calls when the SIM was in another phone.

# Note however that this call timer does NOT support the "minimum call
# lengths" that networks are increasingly using (e.g. a call less than 30
# seconds counts as 30 seconds) - you need wm6minutecount for that,
# which requires a touchscreen phone (otherwise installs but won't display),
# or use my later script SBminutes.py.
# This script can help set up the correct registry entries for wm6minutecount
# after you have installed it.

# Note that, besides not working on no-touchscreen phones, wm6minutecount has
# been known to fail to read logs on WM6.5 phones, and also won't "un-count"
# non-eligible numbers.  So you might prefer to use my SBMinutes script
# instead of this (older) one.

# SIGNAL STRENGTH LOGGER:
# Instead of adjusting the settings, enter S (or s) to make the
# script start logging signal strength, which you can use to
# compare networks etc.  Note the average strength may be misleading if
# the phone is switching between 2G and 3G, because their scales are
# different.  But "% uptime" should still be useful.  If you do start
# the logger, then to completely stop it you sometimes have to switch off.
