iphone TCP/IP 通过配件端口？
我希望能够修改 iPhone tcp/ip 堆栈，以通过串行或更好的 USB 或火线附件端口路由数据包...
我正在研究的应用程序将无法使用 WiFi、3G 或蓝牙... 可以编写自定义应用程序以使用通过附件端口提供的串行端口，但最好支持需要网络访问的通用应用程序。
我没有找到太多与此相关的信息，有人有想法吗？
I'd love to be able to mod the iPhone tcp/ip stack to route packets over the accessory port either serial or better yet USB or Firewire...
The applications I'm researching wouldn't be able to use WiFi, 3G or bluetooth...
Custom apps could be written to use the serial port available via the accessory port, but it would be nice to support generic apps that need network access.
I haven't tracked down much info relating to this, anyone have thoughts??

唯一可行的方法是越狱设备，并进行一些相当低级的黑客攻击。 OS X 支持 NKE（网络内核扩展），允许您引入新的网络接口。我不知道 iPhone 操作系统是否有这些（因为显然没有太多信息 - 它应该是一个黑匣子）。即使确实如此，您也必须让您的 KE 撒谎并声称自己是 Wifi 设备，因为许多应用程序将通过搜索 Wifi 接口来探测网络可用性。
基本上，我认为这是一个站不住脚的想法。您可以使用外部附件 API 来允许自定义应用程序使用您的加密狗作为网络服务提供商，但您不能使用它来提供新的网络接口。如果你想要这种开放的、可扩展的平台，那么 iPhone 并不是真正合适的平台。
About the only way this could work would be to Jailbreak the device, and do some quite low level hacking. OS X supports NKEs (Network Kernel Extensions) that would allow you to introduce a new network interface. I don't know if the iPhone OS has these (as there's obviously not much information on it - it's supposed to be a black box). Even if it did, you'd have to make your KE lie and claim to be e.g. the Wifi device, as many applications will probe for network availability by searching for the Wifi interface.
Basically, I think this is an untenable idea. You can use the External Accessory APIs to allow your custom apps to use your dongle as a network service provider, but you can't use it to provide a new network interface. If you want this kind of open, extensible platform, then the iPhone is not really the right platform.
