Network Setup Protocol Structures and Data Types

fSize	The size in bytes of this structure.
fTSDUSize	The maximum amount of data that packets of this protocol
	can carry. The default is 584.

fDefaultRetryInterval

The default retry interval in milliseconds. By default, this value is 800.

fDefaultRetryCount The default retry count. By default, this value is 3.

fCaseSensitiveCompare

Whether comparisons are case sensitive. The default value is FALSE.

fPad	A pad byte whose value must be zero.

For a detailed description of NBP, 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.

OTCfgATalkGeneralPAP

The OTCfgATalkGeneralPAP structure deﬁnes parameters for the Printer Access Protocol (PAP) component of the AppleTalk protocol stack and is a sub-structure of the OTCfgATalkGeneral structure.

struct OTCfgATalkGeneralPAP

{

UInt16	fVersion;
UInt16	fSize;
UInt32	fDefaultOpenInterval;
UInt32	fDefaultTickleInterval;
UInt8	fDefaultOpenRetries;
UInt8	fDefaultTickleRetries;
UInt8	fDefaultReplies;
Boolean	fDefaultPAPEOMEnabled;
