type SubState 

type SubState uint

SubState is enumeration for the state transitions PSM will have during its execution. The above PUML diagram illustrates what transitions are currently recognized. The Ready state should have 2 internal states: ACK/NACK 

const (
	ACK  SubState = 0x01 << iota // Sub sub state of Ready
	NACK                         // Sub sub state of Ready
	Waiting
	Received
	Decrypted
	Sending
	Ready
	Failure
	Archiving
	Archived
)

States of the PSM`s individual state can be. 

const (
	ReadyACK  SubState = Ready | ACK
	ReadyNACK SubState = Ready | NACK
)
