-**	Was Sie schon immer ueber transfermode negotiation wissen wollten ...
-**
-**	We try to negotiate sync and wide transfer only after
-**	a successful inquire command. We look at byte 7 of the
-**	inquire data to determine the capabilities if the target.
-**
-**	When we try to negotiate, we append the negotiation message
-**	to the identify and (maybe) simple tag message.
-**	The host status field is set to HS_NEGOTIATE to mark this
-**	situation.
-**
-**	If the target doesn't answer this message immidiately
-**	(as required by the standard), the SIR_NEGO_FAIL interrupt
-**	will be raised eventually.
-**	The handler removes the HS_NEGOTIATE status, and sets the
-**	negotiated value to the default (async / nowide).
-**
-**	If we receive a matching answer immediately, we check it
-**	for validity, and set the values.
-**
-**	If we receive a Reject message immediately, we assume the
-**	negotiation has failed, and fall back to standard values.
-**
-**	If we receive a negotiation message while not in HS_NEGOTIATE
-**	state, it's a target initiated negotiation. We prepare a
-**	(hopefully) valid answer, set our parameters, and send back
-**	this answer to the target.
-**
-**	If the target doesn't fetch the answer (no message out phase),
-**	we assume the negotiation has failed, and fall back to default
-**	settings.
-**
-**	When we set the values, we adjust them in all ccbs belonging
-**	to this target, in the controller's register, and in the "phys"
-**	field of the controller's struct ncb.
-**
-**	Possible cases:		   hs  sir   msg_in value  send   goto
-**	We try try to negotiate:
-**	-> target doesnt't msgin   NEG FAIL  noop   defa.  -      dispatch
-**	-> target rejected our msg NEG FAIL  reject defa.  -      dispatch
-**	-> target answered  (ok)   NEG SYNC  sdtr   set    -      clrack
