DTA-POLL (Data transfer systems)

DTA-POLL is a polling package designed to transfer data between a central computer and a number of PCs,LINUX/UNIX/XENIX machines, POS terminals and bespoke devices, connected via PSTN, leased, networked and directly connected lines. Data transferred may be in binary or text format, and multiple data transfers can be processed in any one session. In case of line failure during a session DTA-POLL can pick up at the beginning of the item interrupted. There is no software limit on the number of remote sites to be called during a session, and DTA-POLL will handle as many ports as can be fitted onto the host. The default transfer protocol is the ASCII subset of the IBM 3780 BiSynch protocol, in transparent and non-transparent mode, though external protocols such as KERMIT (TM) or ZMODEM (TM) may also be used.
