Hi. I've managed to create a phonebook entry called
TestConn with the following registry entries.

HKEY_CURRENT_USER\Comm\RasBook\TestConn
Domain = ""
User = ""
DevCfg = (252 length binary...
Entry = (940 length binary...

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConnMgr\Destinations\
TestConn
Default = "{8233...}"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ConnMgr\Providers\{7C
4...1AA}\Connections\TestConn
RequirePw = 1
Enabled = 1
EntryType = 0
DestId = "{8233...}"

Everything seems fine in the Settings\Connections screen.
However I'm unable to dial to the destination as the
current baud rate setting is 19200. This setting has to be
9600. Without manually changing the baud rate, how can I
change it programmatically? Can't seem to use
lineSetDevConfig.

Thanks.
