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
