A full robot vs. robot game now works between two Treos. Added UI to choose BT as transport mechanism, and added new send proc to establish socket connection between host and guest. Works only for two devices: no piconet yet. No error recovery, ability to quit game in middle, start new game, etc.

/* IR strategy. We'll attempt to keep the IR link up, but won't bring it up
|
|
* in the first place, or fix it once it goes down, until there's something
|
|
* to send.
|
|
*
|
|
* So when there's a packet to send, if the link is up
|
|
* (state==IR_STATE_CANDODATA) we just send it. Otherwise we do what's
|
|
* needed to get to that state. What state we're actually in (in the
|
|
* difficult case where we brought the link up before but the players have
|
|
* had their machines separated and the link's died) will, I hope, be
|
|
* tracable by the messages passed to each device's callback.
|
|
*
|
|
* This isn't going to make a game between three or four devices very easy
|
|
* to manage, but perhaps that will have to wait until whatever's wrong with
|
|
* shutting down and restarting links gets fixed.
