Abstract:
1. A method of maintaining connectivity and synchronization of data transmitted over a data communications network, comprising the steps of: automatically capturing the data by operating a mobile reader to read bar code symbols; transmitting the data captured by the mobile reader to a remote host operative to process the captured data over a communications channel having operational attributes; subsequently determining in the mobile reader whether transmission of the captured data to the remote host has been impeded; suspending the transmission of the captured data in response to the determination that the transmission was impeded; storing the captured data in the mobile reader, and queuing the captured data stored in the mobile reader, during the suspending of the transmission; changing the operational attributes of the communications channel during the suspending of the transmission; and resuming the transmission of the captured data queued in the mobile reader over the communications channel with the changed operational attributes.
