The method provides for a way to ensure that the application program running on the host computer handles data received from the at least one mobile computer terminals when one of the mobile computer terminals goes out of range of the wireless network. Communication and association may be established between a mobile computer terminal and an access point on a local network. Then, when it has been determined that communications between the mobile computer terminal and the access point have been impeded, the mobile computer terminal may switch to batch mode to continue data collection.

The device of claim 7 wherein the use information identifying how to invoke a service includes identifications of parameters used when invoking the service and of permissible values for the identified parameters. 9. The device of claim 6 wherein the processing unit is further operative to obtain supported device information over the communications link that identifies at least one type of device that is supported by the server device. 10. The device of claim 9 wherein at least some of the server devices each support multiple types of devices by emulating at least some of those multiple device types, and wherein the supported device information that is obtained by the device for those server devices identifies the multiple types of devices supported by those server devices. 11. A method by which a common data protocol is used to enable a first device of a first device type to communicate with a second device of a second device type over a first communications link, to enable the second device to communicate with a third device of a third device type over a second communications link, and to enable the third device to communicate with the first device over a third communications link, the first device and the second device together forming a first device pair, the second device and the third device together forming a second device pair, and the third device and the first device together forming a third device pair, wherein one of the devices in each of the first, second and third device pairs is a client device and the other of the devices in each of the first, second and third device pairs is a server device, the device pairs such that at least one of the devices is a client device in one device pair and is a server device in another device pair, the method comprising the steps of, for each device pair: establishing a connection between the client device of the device pair and the server device of the device pair using a link protocol; using the link protocol to establish communication between the client device and the server device using the common data protocol; transmitting a type-command from the client device to the service device using the common data protocol, the type-command requesting the service device to provide service information identifying services offered by the server device; and in response to the type-command, transmitting the service information from the server device to the client device. 12. The method of claim 11, further comprising the steps of: transmitting a use-command from the client device of the device pair to the server device of the device pair using the common data protocol, the use-command requesting the server device to provide use information describing use of one of the services offered by the server device; and in response to the use-command, transmitting the use information from the server device to the client device. 13. The method of claim 11, further comprising the steps of: transmitting a service-command from the client device of the device pair to the server device of the device pair using the common data protocol, the service-command identifying a particular service to be performed by the server device; and in response to the service-command, initiating the requested service and transmitting a status-message to the client. 14. A method for enabling a client device to communicate with a server device over a communications link, the method comprising the steps of: establishing a communicative connection with the server device; subsequent to establishing the communicative connection, transmitting a type-command to the server device, the type-command requesting the server device to provide service information defining a set of services offered by the server device; receiving the service information; and subsequent to receiving the service
