John,

My HASP literature says the handshaking starts out per this zig-zag:
                Terminal                Host
                ========                =====
                        -----SOH-ENQ--->

                        <------ACK0-----

                        -----SIGNON--->

                        <------ACK0-----

In other versions the initial SOH-ENQ is shown as only ENQ.
The SIGNON is really DLE-STX....signon message.....DLE-ETX-CRC1-CRC2

The general poll you showed in the original posting looks like 3270 Bisync
rather than HASP to me.

        Good luck,
        Robert Heath
