Network Setup Protocol Structures and Data Types

OTCfgRemoteServerPort

The OTCfgRemoteServerPort structure stores core conﬁguration information for the personal server.

struct OTCfgRemoteServerPort {
UInt32	version;
SInt16	configID;
Str255	password;
OTCfgRemoteAnswerMode	answerMode;
Boolean	limitConnectTime;
UInt8	pad;
UInt32	maxConnectSeconds;
OTCfgRemoteProtocol	serialProtoFlags;
OTCfgRemoteNetworkProtocol	networkProtoFlags;
OTCfgRemoteNetAccessMode	netAccessMode;
Boolean	requiresCCL;
char	portName[64];
char	serialLayerName[kMaxProviderNameSize];
InetHost	localIPAddress;
};

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.
configID	The ID of this port configuration. The ID must match an
	element of the configIDs array in the OTCfgRemoteServer
	(page 136) structure. For the personal server, configID must
	be zero.
password	The security zone bypass password in plain text.
answerMode	The answer mode. For possible values, see the
	OTCfgRemoteAnswerMode (page 169) enumerations.
limitConnectTime	Set to 1 to limit the length of incoming connections. Set to
	zero for unlimited connection time.
pad	Must be zero.
maxConnectSeconds	The maximum length of a incoming connection in seconds
	if limitConnectTime is set to 1. The default is 3600.
