Abstract
A communications method (40) provides for synchronisation between a mainframe computer (2) and a large number of hand-held terminals (HHTs) (4). An intermediate communications controller (3) searches for identifier fields (20,21) and generates a key (22) and refers to a reference database (23). Depending on values in a transmit counter and on data in a current record (18) and a reference record (23(a)), various actions may be taken including writing of a record to an OUT file (31). The OUT files (31) has a similar structure to an incoming file (INP) and the structure is to optimise facilities available in the HHTs (4).
