I believe any command other than login (or logout?) is invalid before you
hit full-feature phase. Thus any other such command would count as 020b.

<PAT> It is any command other than login. Logout is not used during login
phase.

Either Reject or NotUnderstood come to mind.

<PAT> NotUnderstood shouldn't be used. It is specifically for cases where
the key is not understood and all implementations would understand the key
ImmediateData.  Assuming that a value of Ye for a boolean would be
considered a value not admissible, then the reaction depends on whether the
initiator is the requester or the responder for that value. 4.2.2 says a
value of REJECT or an admissible value MAY be returned when the requester
offers an inadmissible value. If an inadmissible values is received from the
responder, then it is a negotiation failure. 

Take care,
