A data communications system to provide for the dynamic modification of a queue of documents arranged sequentially for transmission. An operator interacts with the send queue by making the send queue selection from a menu of communication request tasks on a display. Selection of the addition to the send queue option invokes a routine to add a send job. Operator selection of the display send queue option invokes a routine to display the send queue in the display for review of the current send queue and its status. A delete send job option invokes a routine to allow the operator to delete any job from the send queue except the one currently being sent. The select next send job option invokes a routine to allow the operator to start or restart the sending process from any point within the send queue.
