Abstract

An open network system for supporting input/output (I/O) operations for non-standard I/O devices are disclosed. The system includes a server coupled to a plurality of I/O devices through an open network and an extended open system protocol that supports communication with devices that are not personal computers (PCs). These devices include magnetic stripe readers, check readers, smart card readers, credit card terminals, screen phone terminals, PIN pads, printers, and the like. The extended open network protocol includes tags which identify device and input operations and attributes which identify the location, data exchange method, and data variable names for the retrieval, acquisition, and submission of data between the server and I/O devices. Preferably, the open network protocol is implemented in a Hyper Text Transport Protocol (HTTP). Preferably, the system includes a common gateway interface (CGI) at the server which converts protocol statements communicated between the server and I/O devices to application language statements for providing data to an application program coupled to the server. Most preferably, the application statements and protocol statements are constructed in integrated statements with an editor. The editor ensures that data identifiers in the application and protocol statements are compatible. The integrated statements are then parsed by the editor to segregate the protocol statements from the application statements. The protocol statements are downloaded in a file to a client program at an I/O device for processing. The application statements are stored in a file for use by the application. In this manner, generation of the files for client and application processing are automatically done without the user ensuring the correlation of the data fields in the two files.

Claims

1. An open network processing system comprising:

a server program coupled to an open network;

a non-standard input/output (I/O) device coupled to said open network; and

a client program for communicating data in an extended open network protocol between said server program and said non-standard I/O device, said extended network protocol including one identifier for said non-standard I/O device for a transaction and an identifier for an operation to be performed with said identified non-standard I/O device.

2. The system of claim 1, wherein said client program communicates said data in files having protocol statements conforming to said extended open network protocol.

3. The system of claim 2, wherein said files are identified by universal resource locators.

4. The system of claim 2, said server program further comprising a common gateway interface.

5. The system of claim 4, said common gateway interface providing data from said protocol statements conforming to said extended open network protocol to a transaction system.

6. The system of claim 5, said common gateway interface receiving data from said transaction system and providing said data in a file to said client program.

7. The system of claim 5, said common gateway interface correlating data in said protocol statements conforming to said extended open network protocol with data fields in database files for a database coupled to said server.

8. The system of claim 7, wherein said database files are passed to an application program for accessing said database coupled to said server.

9. A method for processing data over an open network for non-standard input/output (I/O) devices comprising the steps of:

coupling a server program to an open network;

coupling a non-standard I/O device to said open network;

communicating data conforming to an extended open network protocol between said server program and said non-standard I/O device;

identifying said non-standard I/O device in a protocol statement conforming to said extended network protocol; and

identifying an operation to be performed with said identified non-standard I/O device.

10. The method of claim 9, said communicating step further comprising the step of:

using a client program to communicate said data between said server program and said non-standard I/O device in protocol statements that conform to said extended open network protocol.

11. The method of claim 10 further comprising the steps of:

grouping said protocol statements in files for said communication between said server program and said non-standard I/O device; and

identifying said files with universal resource locators.

12. The method of claim 9 further comprising the step of:

coupling a common gateway interface to said server program, said common gateway for communicating data between a database and said server program.

13. The method of claim 12, said common gateway interface further performing the step of:

providing data from protocol statements conforming to said extended network protocol to a transaction system, said protocol statements being received in a file from said client program.

14. The method of claim 13, said common gateway interface further performing the step of:

receiving data from said transaction system and providing said data to said client program in a file.

15. The method of claim 13 further comprising the step of:

correlating data in extended open network protocol statements with data fields in database files.

16. The method of claim 15 further comprising the step of passing database files to an application program for accessing said database.

17. An open network processing system comprising:

a server program coupled to an open network, said server program including a common gateway interface;

a non-standard input/output (I/O) device coupled to said open network;

a client program for communicating data in an extended open network protocol between said server program and said non-standard I/O device, said client program communicating said data in files having protocol statements conforming to said extended open network protocol; and

said common gateway interface provides data from said protocol statements conforming to said extended open network protocol to a transaction system, correlates data in said protocol statements conforming to said extended open network protocol with data fields in database files for a database coupled to said server, and receives data from said transaction system to provide said data to said client program.

18. The system of claim 17, wherein said database files are passed to an application program for accessing said database coupled to said server.

19. A method for processing data over an open network for non-standard input/output (I/O) devices comprising the steps of:

coupling a server program to an open network;

coupling a non-standard I/O device to said open network;

communicating data conforming to an extended open network protocol between said server program and said non-standard I/O device;

coupling a common gateway interface to said server program, said common gateway for communicating data between a database and said server program;

providing data from protocol statements conforming to said extended network protocol to a transaction system, said protocol statements being received in a file from said client program;

receiving data from said transaction system and providing said data to said client program in a file; and

correlating data in extended open network protocol statements with data fields in database files.

20. The method of claim 19 further comprising the step of passing database files to an application program for accessing said database.
