Network Setup Protocol Structures and Data Types

Field descriptions

fVersion	Must be 1.
fSize	The size in bytes of this structure.

fDefaultOpenInterval

The default open interval in milliseconds. The default value is 2000.

fDefaultTickleInterval

The default tickle interval in milliseconds. The default value is 15000.

fDefaultOpenRetries

The default number of times to retry an opening. The default value is 0.

fDefaultTickleRetries

The default number of times to retry sending a tickle. The default value is 8.

fDefaultReplies Must be 8. This ﬁeld is ignored by current versions of Open Transport.

fDefaultPAPEOMEnabled

By default, FALSE.

For a detailed description of PAP, see Inside Macintosh: Networking with Open Transport and Inside AppleTalk, Second edition.

No preference type is deﬁned for this structure. Instead, access this structure through the OTCfgATalkGeneral (page 145) structure, which has a preference type of kOTCfgATalkGeneralPref.

OTCfgATalkGeneralZIP

The OTCfgATalkGeneralZIP structure deﬁnes parameters for the Zone Information Protocol (ZIP) component of the AppleTalk protocol stack and is a sub-structure of the OTCfgATalkGeneral structure.

struct OTCfgATalkGeneralZIP
