alameda 0.1 - JAD (Java Application Descriptor) downloader for Motorola phones
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alameda is the open-source Linux counterpart of Motorola's MIDway Tool (see
http://developer.motorola.com/?path=1.2.6.28). It allows you to load a
JAD file and accompanying JAR file to a Motorola cellular phone attached
to your PC using a serial cable. Most phones with USB connections also fall
into this category since their drivers emulate a serial port on the PC.

REQUIREMENTS
~~~~~~~~~~~~
- A working connection between your phone and your PC. For USB devices, this
  means that the appropriate driver must be loaded to make a /dev/ttyACMn
  device usable (for details on modifying the stock kernel drivers for this,
  look at the appropriate section below).
  For both types (serial and USB), this means that the phone must respond
  to AT commands in, eg. minicom.
- On your phone, the "Java App Loader" must be enabled. Once selected and the
  cables unplugged, future connections are in a special mode that allows
  Java applications to be downloaded into your phone. The phone should
  no longer be responsive to AT commands.
  If you do not have this menu item in your settings menus anywhere, search
  the web for ways of enabling access to it. That is beyond the scope of
  this program.
- Uh, a JAD file and a JAR file to download. This means either a game,
  a browser (Opera Mini), etc. or your own.

HOW TO USE
~~~~~~~~~~
1. Adjust the define at the top of alameda.c to reflect the device you want
   to use:
#define DEVICE "/dev/ttyACM0"

2. Compile alameda:
make

3. Execute it with the JAD file:
./alameda example.jad

Note that the MIDlet-Jar-URL attribute in the JAD file must be such that
alameda can find the corresponding JAR file by simply opening the filename.
This means that URLs will NOT work, nor will most complicated path structures.
For best results, stick with just the filename, place everything in the
same directory, and run alameda from that same directory.

MODIFYING THE STOCK ACM (USB) DRIVERS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The cdc-acm module, included in the vanilla kernel distribution of Linux 2.6,
is the correct driver for most phones' USB serial emulation. However, they're
not loaded when a phone is plugged in. The problem is that the device IDs for
insertion of these drives are too restrictive out-of-the-box.

A quick hack is to add laxer filters to the device ID tables. Get ready
to compile a new kernel (or at least the cdc-acm module). Open
drivers/usb/class/cdc-acm.c. Scroll down to the definition of the acm_ids
table (90% into the file; line 1063 in 2.6.17.11). Add the following lines
at the end of the table:

	{ USB_DEVICE_INFO(USB_CLASS_COMM, 0, 0) },
	{ USB_DEVICE_INFO(USB_CLASS_COMM, 2, 0) },
