I do not exactly understand what you mean.

There is a Wiki trying to document how all the functional areas (WLAN, BT, GPS, UMTS, ...)
of the GTA04 can be accessed from user space. Some have /sys files
others have /dev files, some have ioctls or alsa mixer settings.

asap which means anytime this year :) I am just trying to catch up with all these
changes and trying to understand them myself. 'cause I am the "hardware guy".

I don't know. The FSO developers should be able to answer this.

The best help is to ask Neil Brown. He has written the latest kernel and driver code.

I think you have to use 3 MBit, i.e. 3000000. There have only been some rare
boards with 115200. All others have 3 MBit.

Yes, that looks like bad baudrate.

Yes, if communication works.

Do you have your GTA04 serial number? Then you could
try to look up the factory test which says something about
the baudrate.
