};
version	Must be 1 for Open Transport/PPP or 3 for ARA.
fWindowPosition	Global coordinates for the application’s window position.
tabChoice	Currently active tab in the Options dialog box. Use 1 for the
	Redialing tab, 2 for the Connection tab, or 3 for the Protocol
	tab.
fUserMode	The current user mode. See the OTCfgUserMode preference
	(page 109) enumeration for possible values.
fSetupVisible	Set to 1 to display the set up or zero to hide it.

The preference type for this preference is kOTCfgRemoteApplicationPref, which is deﬁned as 'capt'.

OTCfgRemoteARAP

The OTCfgRemoteARAP structure stores connection information used by the ARAP modules.

struct OTCfgRemoteARAP

{
UInt32	version;
char	lowerLayerName[kMaxProviderNameSize];
};

Field descriptions

version	Depending how the preference was constructed, version
	may be kOTCfgRemoteDefaultVersion or
	kOTCfgRemoteAcceptedVersion. When reading the version
	ﬁeld, accept either value. When writing the version ﬁeld,
	set it to kOTCfgRemoteDefaultVersion.
lowerLayerName	A C string containing the name of the underlying modem
	port, which must be “Script”.

The preference type for this preference is kOTCfgRemoteARAPPref, which is deﬁned as 'arap'.
