I am developing an application on a device with os Windows ce3.0 Handheld PC 2000. My application is depending on a GPRS connection. So i wrote a couple control function in my application. First of all my application checks if there is an GPRS connection active. if not then it starts the connection using RasDial(). But somethimes when my application starts the connection it fails with the following error: ERROR_PORT_NOT_AVAILABLE The strange thing is that the Nokia Manager application tells me there is no GPRS connection active. But when I try to activate the connection it immidiatly pops up with a "disconnected" message following "ready to activate GPRS". But when i try it again, of course it fails again. The only thing I can do is remove the d211 from my device and insert it again to solve the problem. Is this a bug in the nokia driver? Does anybody have had simmilar problems and how did they solved it?
