 ** @(RTN20c)@ When @CONNECTING@, if the operating system indicates that the underlying internet connection is now available, the client should restart the pending connection attempt
 * @(RTN16)@ @Connection@ recovery:
 ** @(RTN16i)@ Connection recovery is similar to connection resumption (see "RTN15c":#RTN15c), except that instead of the library resuming from a time at which that library instance was previously connected, it is doing so from external state provided in the client options, "(TO3i)":#TO3i. Since the library has no state at the time of connection, the channels must be explicitly attached by the user; continuity preservation is achieved by the @channelSerial@s for each channel being stored in the recovery key.
-** @(RTN16f)@ When a library is instantiated with the @recover@ client option, it should initialize its internal @msgSerial@ counter to the @msgSerial@ component of the @recoveryKey@. (If the recover fails, the counter should be reset to 0 per "RTN15c7":#RTN15c7 )
+** @(RTN16f)@ When a library is instantiated with the @recover@ client option, it should initialize its internal @connectionId@ and @msgSerial@ counter to the @connectionId@ and @msgSerial@ component of the @recoveryKey@. (If the recover fails, the counter should be reset to 0 per "RTN15c7":#RTN15c7 )
 ** @(RTN16j)@ When a library is instantiated with the @recover@ client option, for every channel/channelSerial pair in the @recoveryKey@, it should instantiate a corresponding channel and set its "RTL15b":#RTL15b @channelSerial@.
 ** @(RTN16k)@ When the library first connects to Ably after being instantiated with a @recover@ client option, it should add an additional @recover@ querystring param to the websocket request, set from the @connectionKey@ component of the @recoveryKey@. Once the library has successfully connected to Ably, it should never again supply a @recover@ querystring param.
-** @(RTN16g)@ @Connection#createRecoveryKey@ is a function that returns a string which incorporates the @connectionKey@, the current @msgSerial@, and a collection of pairs of channel @name@ and current @channelSerial@ for every currently attached channel.

 *** @(RTN16g1)@ It must be serialized in a way which is able to encode any unicode channel name. The SDK may assume that the recovery key will only be consumed by the same type of SDK, so this spec does not specify any particular serialization; however, the format should be forward-compatible through the same major version of the SDK.
 *** @(RTN16g2)@ It should return @Null@ when the SDK is in the @CLOSED@, @CLOSING@, @FAILED@, or @SUSPENDED@ states, or when it does not have a @connectionKey@ (for example, it has not yet become connected).
 ** @(RTN16d)@ The library may wish to test that after a connection has been successfully recovered, the @Connection#id@ should be identical to the @id@ of the connection that was recovered, and @Connection#key@ should have been updated to the @ConnectionDetails#connectionKey@ provided in the @CONNECTED@ @ProtocolMessage@.
