Abstract
Methods, data processing systems and program products provide delayed generation and encoding of data transmissions by storing a reference to a message to be transmitted as an entry in a transmission request queue. After establishing a communication connection between a host data processor and the portable data processor, the message corresponding to the entry in the transmission request queue is generated, encoded and then transmitted to the host data processor over the communication connection. If user input is received which requests that information resident in the data processor be modified, the data processor determines if the information associated with the modification request includes information contained in a message associated with an entry in the transmission request queue. If the information associated with the modification request includes information contained in a message associated with an entry in the transmission request queue then a copy of the information associated with the modification request is created. A copy is created to provide a version of the unmodified information for use in generating the message associated with the entry in the transmission reques…
