This is a question about RAS on Windows CE 4.2 (.NET).
Using a MultiTech GPRS modem, we have implemented a Ras handler to connect the modem to internet using a wireless carrier. This used to work great on CE 3.0, and works great on CE4.2 except on one specific US network.
On this particular network; the connection failed about 10% of the time with RASCS_AuthNotify and error 660. The only documentation I can find on this error tell me that a command wouldn't be supported in the .ini file. What file? CE 4.2 does not comes with modem .inf file (not that I can find it). Any way to find what command wasn't supported?
The carrier have confirmed that even when we see that error; they see the device as being connected on the network with no data being sent; they also see the disconnection request. Any idea how to resolve; or more info on how to investigate?
