Built-in Communications Tools

Serial Tool

The following is an example of how to create an endpoint that uses the standard
asynchronous serial tool:

myAsyncEP := {_proto:protoBasicEndpoint};
myOptions := [

{ label: kCMSAsyncSerial,
type: 'service,
opCode: opSetRequired } ];

returnedOptions:= myAsyncEP:Instantiate(myAsyncEP,

myOptions);

Table 24-1 summarizes the standard serial options. Each of these options is
described in detail in "Options for the Standard Asynchronous Serial Tool"
(page 21-2) in Newton Programmer's Referencee.
