Built-in Communications Tools
AppleTalk Tool 24-9
The infrared tool uses the Sharp Infrared protocol. Because of the characteristics of
this protocol, Apple recommends setting
sendFlags to kPacket and to kEOP
every time you send data. For more information on sendFlags see, “Sending
Data” (page 23-11).
If you don’t set sendFlags as recommended above, the tool only sends data after
it queues 512 bytes of data, which means that input scripts do not terminate as you
might expect. On the receiving side, the queuing means you terminate after every
output if you set
useEOP to true . If you are using byteCount , you should set
useEOP to nil to trigger on byteCount instead of EOP . For more information on
useEOP and byteCount , see “Specifying Data Termination Conditions”
(page 23-14).
AppleTalk Tool 24
The AppleTalk tool enables access to the ADSP (Apple Data Stream Protocol
component of the AppleTalk protocol stack.
The following is an example of how to create an AppleTalk endpoint:
myATalkEP := {_proto:protoBasicEndpoint};
myOptions := [
{ label: kCMSAppleTalkID,
type: 'service,
opCode: opSetRequired
},
{ label: kCMSAppleTalkID,
type: 'option,
opCode: opSetRequired,
data: { arglist: ["adsp"],// or KCMOAppleTalkADSP
typelist:[
'struct
['array, 'char, 4]
]
}
},
{ label: kCMOEndpointName,
type: 'option,
opCode: opSetRequired,
data: { arglist: [kADSPEndpoint],
typelist:[
'struct
['array, 'char, 0]
]
