How to I detect whether a tty belonging to a gsm/3g-modem is a data or control port?
问题 I'm currently writing a small tool for a linux router that sets up a wwan (gsm/3g) connection when I plug an appropriate modem into its USB port. When the device is plugged in several ttys are registered and I currently maintain a list of manufacturers and devices and which of their registered ttys is the control / data port. If possible I want to get rid of this list and find a way to somehow probe the registered ttys directly to check if they are a control port or a data port. I examined
Incorrect Response - Reachability For WWAN
问题 While checking for reachability(network availability) of an iPAD 3 WiFi+Cellular, I ran into across a weird issue that happened in the below mentioned scenario. To check network availability I have used Apple sample code for reachability. The following code was implemented to check availability of WiFi or WWAN. ` - (BOOL)networkCheck { Reachability *wifiReach = [Reachability reachabilityForInternetConnection]; NetworkStatus netStatus = [wifiReach currentReachabilityStatus]; switch (netStatus)

How do I check connection type (WiFi/LAN/WWAN) using HTML5/JavaScript?
I wish to tailor a particular website to a low bandwidth version if the client is connected via WWAN (metered) connection or otherwise. The connection type is important for the site to know if it should provide a rich experience or a bandwidth efficient experience. My desktop runs on a metered connection and in the future, more desktops will be connected via metered cellular networks (including Windows 8 tablet PCs), efficient web-apps should respect that a user might not require high detail assets on a pay-per-byte-connection.
