1. For transferring information between a TN3270 client on a Telnet connection and a host on an SNA connection, the host maintaining a parameter table of local-unit parameter sets identified by respective model strings, a communications gateway including circuitry for:

  • A) performing a TN3270 negotiation with the TN3270 client by way of a Telnet connection and thereby obtaining a device-type designation therefrom;

    B) algorithmically generating a computed model string as a function of the device-type designation;

    C) associating a given logical-unit process with the TN3270 client;

    D) by way of the SNA connection, using the computed model string to identify to the host the parameter set in accordance with which the given logical unit is to communicate; and

    E) transferring information between the host and the TN3270 client by;

    i) employing the Telnet connection to communicate with the TN3270 client; and

    ii) employing the logical-unit process to communicate with the host by way of the SNA connection.
