connect to charging / sync socket to LAN
If you go "from the cradle" to the Network, then it is possible, but to present the PDA as an independent host .... it is assumed that it is impossible.
The fact is that it is possible and possible to solder something iron, but another problem arises, which I was popularly explained that it is impossible to do anything: the IP address is hardwired for the resource "Serial on USB".
Therefore, to present a PDA, seated in a cradle, as an independent host on the subnet will be extremely prolly ...
And most of the applications that I tried to incite on LAN in this workaround, refuse to recognize it and terb or LAN card, or modem.
