Offhand, I can think of two possibilities.

Redefine/Extend RMPPType.
	3: STOP send packet; shall be sent only from Receiver to Sender.
	4: ABORT send packet; shall be sent only from Receiver to Sender.
	5: STOP receive packet; shall be sent only from Sender to Receiver.
	6: ABORT receive packet; shall be sent only from Sender to Receiver.

or

Extend RMPPStatus.

	Determine which STOP/ABORT messages may be transfered
	either direction.
	Define existing values as applying only from Receiver to Sender.
	Define new values (in current reserved range) as applying
	only from Sender to Receiver.

I prefer the first option, but there may be other options that I'm overlooking.
