The following example uses the RAS namespace for the Mobile Devices SDK to make the Internet connec-

tion. See Chapter 12: “RAS (Remote Access Service)” for more information.

19.7.2 Windows Mobile and Windows Embedded Hand-Held

For Windows Mobile operating systems, Microsoft provides the Connection Manager API. This replaces RAS

for making WWAN connections.

For a list of Psion computers that support Connection Manager and that support RAS see

Section 12.2 Support for RAS and Windows Connection Manager on Psion Computers on page 87.

For more information on using the Connection Manager API, visit the following URLs:

See also Section 19.7.3 The DbGprs.csv File on page 209 for information that may need to be provided to

complete the connection.
