1. A method of acquiring correspondence between a node and a terminal device, which uses a system comprising a computer connected to a network and a plurality of said terminal devices connected to said network, whereinwhen said computer sends a command into said network for operating or stopping an operation of said terminal device, said computer sends out said command with an automatically assigned node number while sequentially changing the automatically assigned node number to a number other than the node number of said computer,said terminal device in of said plurality of terminal devices said network receives said command and, in response, starts operating or stops the operation,said computer monitors said operating or said stopping of the operation and recognizes a correspondence between the node number sent out together with said command and a timing of the terminal device operating or stopping the operation based on the timing of the command thus sent out, andby performing said monitoring and said recognizing for each sequentially changed automatically assigned node number, a correspondence between a plurality of node numbers and said plurality of terminal devices is acquired from said recognition.

Abstract
The connection verifiable information processing system of the invention comprises: a system service 5 which outputs a first transmit request to request an output of connection information, and which processes response information to the first request, the response information being described following a first format; a WDM driver 7 which outputs a second request to request an output of connection information, and which receives response information described following a second format that a WDM compliant device 8 outputs in response to the second transmit request, while remaining unresponsive to the first transmit request; and a second FSD 13 which converts the response information described following the second format received by the WDM driver 7 into response information of the first format that the system service can process.

1. A method of acquiring correspondence between a node and a terminal device, which uses a system comprising a computer connected to a network and a plurality of said terminal devices connected to said network, wherein
when said computer sends a command into said network for operating or stopping an operation of said terminal device, said computer sends out said command with an automatically assigned node number while sequentially changing the automatically assigned node number to a number other than the node number of said computer, said terminal device in of said plurality of terminal devices said network receives said command and, in response, starts operating or stops the operation, said computer monitors said operating or said stopping of the operation and recognizes a correspondence between the node number sent out together with said command and a timing of the terminal device operating or stopping the operation based on the timing of the command thus sent out, and by performing said monitoring and said recognizing for each sequentially changed automatically assigned node number, a correspondence between a plurality of node numbers and said plurality of terminal devices is acquired from said recognition.

7. A method of acquiring correspondence between a node and a terminal device, which uses a system comprising a computer connected to a network and a plurality of terminal devices connected to said network, wherein
when said computer sends data into said network to be slaved back on said terminal device, said computer sends out said data with an automatically assigned plurality of node numbers while sequentially changing the automatically assigned node numbers to another number other than a node number of said computer, said computer monitors said playback, and recognizes a correspondence between the node numbers sent out together with said data and a timing for the terminal device playing back said data, and by performing said monitoring and said recognizing for each sequentially changed automatically assigned node number, a correspondence between said plurality of node numbers and said plurality of terminal devices is acquired from each result of said recognition.

16. A computer which uses a system comprising a computer connected to a network and a plurality of terminal devices connected to the network, said computer comprising:
-
input means of inputting one of an automatically assigned node number and a device number, other than a node number of said computer, to a terminal device having (1) a second interface which receives a command sent out from said computer via said network and (2) control means for performing control so as to execute said command received via said second interface; and a first interface which sends out into said network a command for operating or stopping an operation of said terminal device, while sequentially changing said one of said node number and said device number input by said input means, wherein said command, alone with said one of said node number and said device number, is sent to said terminal device via said network, said computer monitors said operating or said stopping of the operation and recognizes a correspondence between said one of the node number and the device number sent out together with said command and a timing of said terminal device operating or stopping the operation based on the timing of the command thus sent out, and by performing said monitoring and said recognizing for each sequentially changed one of said node number and said device number, a correspondence between a plurality of node numbers or device numbers and said plurality of terminal devices is acquired from said recognition. - View Dependent Claims (18, 19)

17. A computer which uses a system comprising said computer connected to a network and a plurality of terminal devices connected to said network, said computer comprising:
-
a first interface which, when said network is reset, sends out a command for requesting a node unique ID to said terminal devices into said network, while sequentially changing one of a node number and a device number as a destination ID or by appending to said command a description as a destination ID indicating delivery to all connected devices, and said terminal device comprising (1) a second interface which receives said command sent out from said computer via said network, (2) control means for performing control so as to execute said command received via said second interface, and (3) a second memory which is referenced by said second interface and which stores said node unique ID unique to said device to be transmitted to said computer; a first memory for storing a list carrying said node unique ID or a name designating said terminal device in corresponding relationship to said node number; and converting means for creating said list and storing the same in said first memory at the time of the first reset, and for updating said list for each reset thereafter, and wherein; when said first interface sends the command for requesting said node unique ID into said network, said second interface returns said node unique ID to said first interface via said network in response to said command, said first interface receives said node unique ID sent out from said second interface via said network, said converting means creates or updates said list by using said node unique ID received from said each terminal device, and correspondence between each node and each terminal device is obtained by referencing said list.

20. A terminal device which uses a system comprising a computer connected to a network and a plurality of terminal devices connected to the network, said terminal device comprising:
-
a second interface which receives a command sent out via said network from said computer having (1) input means for inputting an automatically assigned node number other than a node number of said computer and (2) a first interface which sends out into said network a command for operating or stopping an operation of said terminal device while sequentially changing said node number input by said input means; and a control means for performing control so as to execute said command received via said second interface, wherein said command with said node number is sent to said terminal device via said network, said computer monitors said operating or said stopping of the operation and recognizes a correspondence between the node number sent out together with said command and a timing of said control means operating or stopping the operation based on the timing of the command thus sent out, and by performing said monitoring and said recognizing for each sequentially changed node number, a correspondence between a plurality of node numbers and said plurality of terminal devices is acquired from said recognition. - View Dependent Claims (21, 23, 24, 25, 26)
