		CALL QZLSMAINT PARM('40' '2' '0X580')
		// Force SMB2
		CALL QZLSMAINT PARM('40' '1' '0X100')


For IBM i 7.4 and later:

	Restore to default (SMB1, SMB2, and SMB3)

		// Clear the SMB version support flags
		CALL QZLSMAINT PARM('40' '2' '0X1580')

	Support only SMB1

		// Clear the SMB version support flags
		CALL QZLSMAINT PARM('40' '2' '0X1580')
		// Disable SMB2 and SMB3
		CALL QZLSMAINT PARM('40' '1' '0X1080')

	Support only SMB2

		// Clear the SMB version support flags
		CALL QZLSMAINT PARM('40' '2' '0X1580')
		// Force SMB2 and disable SMB3
		CALL QZLSMAINT PARM('40' '1' '0X1100')

	Support only SMB1 and SMB2

		// Clear the SMB version support flags
		CALL QZLSMAINT PARM('40' '2' '0X1580')
		// Disable SMB3
		CALL QZLSMAINT PARM('40' '1' '0X1000')

	Support only SMB2 and SMB3

		// Clear the SMB version support flags
		CALL QZLSMAINT PARM('40' '2' '0X1580')
		// Force SMB2 and higher
		CALL QZLSMAINT PARM('40' '1' '0X100')

	There is no current flag combination to force the server to only negotiate SMB3, but a user can force clients to use SMB3 by requiring encrypted connections in the NetServer configuration.
