Abstract:
1. A method of maintaining connectivity and synchronization of data transmitted over a communications network, comprising the steps of: a) displaying a graphical user interface having data fields on a mobile computer terminal; b) automatically capturing symbol data by electro-optically reading bar code symbols, and filling in at least one of the data fields with the symbol data; c) configuring delivery of the data by manually entering, into other of the data fields, delivery data identifying a selected carrier, a selected data type, and a selected delivery time; d) transmitting the data, including the symbol data and the delivery data, of the selected data type from the mobile terminal via the selected carrier at the selected delivery time over an initial communications channel to a remote host computer; e) determining, in the mobile terminal, whether transmission of the data over the initial channel is impeded; f) suspending transmission of further data after determining that data transmission over the initial channel has been impeded; g) storing and queueing the further data in the mobile terminal; h) establishing an alternative communications channel between the mobile terminal and the host computer; and i) transmitting the further data stored in the mobile terminal to the host computer over the alternative communications channel.
