I have a usb adsl modem. There is an app the runs in system tray that indicates if modem is connected\if there is traffic comming through etc. Presuming this software is looking at the drivers, I need to be able to do the same in vb, so that I can change over to a isdn backup link when the adsl goes down. Any hints at where to start looking (i'm completeley stummped) would be appreciated.
