Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A communication subsystem in a data processing system comprising: Application means for generating first requests for said system to perform prescribed functions to accomplish a specified job; Network Terminal Driver means coupled to said application means and responsive to said first requests for generating a plurality of control buffers, said Network Terminal Driver means including first and second module means responsive to information stored in said plurality of control buffers for generating a sequence of orders; Terminal Driver means coupled to said Network Terminal Driver means and responsive to said sequence of orders for performing said prescribed functions.
Claim 2
Dependent Claim
98 words
A communication subsystem in a data processing system comprising: Application means for generating first requests for said system to perform prescribed functions to accomplish a specified job; Network Terminal Driver means coupled to said application means and responsive to said first requests for generating a plurality of control buffers, said Network Terminal Driver means including first and second module means responsive to information stored in said plurality of control buffers for generating a sequence of orders; Terminal Driver means coupled to said Network Terminal Driver means and responsive to said sequence of orders for performing said prescribed functions.
Claim 3
Dependent Claim
33 words
The communication subsystem/claim 1 wherein said first module means comprises: Kernel Module means responsive to said first requests for generating one of said plurality of control buffers and a plurality of second requests.
Claim 4
Dependent Claim
40 words
The communication subsystem of claim 2 wherein said first module means further comprises: Application Module means coupled to said Kernel Module means and responsive to said one of said plurality of control buffers for generating a plurality of third requests.
Claim 5
Dependent Claim
71 words
The communication subsystem of claim 3 wherein said first module means further comprises: Provider Module means coupled to said Kernel Module means and responsive to said plurality of second requests for generating a common set of said plurality of control buffers for each of said one of said plurality of control buffers; and responsive to said plurality of third requests for generating a specific set of said plurality of control buffers.
Claim 6
Dependent Claim
68 words
The communication subsystem of claim 3 wherein said second module means comprises: said Kernel means responsive to both said common set and said specific set of said plurality of control buffers for managing a sequence of both said common set and said specific set of said plurality of control buffers; said kernel means being further responsive to first indications from said Provider Module means for managing said sequence.
Claim 7
Dependent Claim
60 words
The communication subsystem of claim 5 wherein said second module further comprises: said provider module means responsive to said sequence of both said common set and said specific set of said plurality of control buffer for generating said sequence of orders; said Provider Module means is further responsive to second indications from said terminal means for generating said first indications.
Claim 8
Dependent Claim
15 words
The communication subsystem of claim 1 wherein said first requests are Input Output Request Buffers.
Claim 9
Dependent Claim
21 words
The communication subsystem of claim 2 wherein said one of said plurality of control buffers is a Provider Module Control Block.
Claim 10
Dependent Claim
22 words
The communication subsystem of claim 4 wherein said common set of said plurality of control buffers are common Device Driver Control Blocks.
Claim 11
Dependent Claim
22 words
The communication subsystem of claim 4 wherein said specific set of said plurality of central buffers are specific Device Driver Control Blocks.
