/* 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.
