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,
