Declarations
<<Presently not used.>>
definitions to interface to DECTalk text-to-speech synthesizer; more in ThSmartsPrivate
DSR brief () not strictly needed for reset or flush, but makes the DECTalk (which is normally quiet in this case) respond more like the Prose.
Byte (char) count; RPCLupine.maxDataLength is word count
No bigger than RPCLupine.maxDataLength - 2*indexMarkerLen
maxClientMarker: INT = 199; -- in ThSmartsPrivate
maxControlMarker: INT = 250; -- in ThSmartsPrivate
External  Procedures
Each select statement combines cases to execute a subset of the required actions efficiently.
If trunkTalking was requested, we must enter either trunkTalking or trunkForwarding, depending on whether the other end of the connection is on the same machine.
When leaving talking state but not going idle, must explicitly take down Ethernet connection.
Does this ever happen?
Queue up request to eliminate connections.
Select tone/tune specifications.
Go offhook and enter speakerphone mode if noises need to be heard and phone isn't offhook
Go back onhook when idling from spkr (not sPkr) or monitor mode.
<<Alternative: leave it in state fls until now.>>

Internal  Procedures
In a loop, keep the state of the Lark up to date.  Awakens itself whenever any pending
tone is otherwise likely to time out.  Awakened by EnterLarkState whenever the state
of tones, switches, and the like might have to change.
sInfo is the SmartsInfo in use when the process was initiated.  It's used to report errors, but bear in mind that it may or may not be the one in effect when a particular complaint occurs.
speechDone (or some control marker) is needed to keep the Prose going if new text comes in after the last bit of the previous request was sent, but before the Prose finishes speaking it.  Triggers a call from LarkInImpl.HandleProseOutput.
Scan backward from the end of the packet for a place to break between words.  The Prose treats an index marker as a word terminator.  Keep punctuation with its preceding word for correct prosodics.
Too long between break chars; just make progress somehow.
Make sure not to break in the middle of a client marker!!
Maybe just as satisfactory to treat each elt of list as separate request & terminate with CommenceSpeech to keep Prose going.
<<NIL => revert.  Remember to change 2d parameter next time Lark.mesa changes.>>
Connect output buffer
Remove chars that the Prose considers illegal.
Called only from LarkSupervisor, whose sequentiality implies that no locks are needed.

This list is a queue - you expect the notifications to return in the order you sent them.  LarkSupervisor "fails" if you don't get back the first thing in the queue.
Queue is a FIFO list of REFs, with a lastAction pointer to aid in rapid enqueuing. 
Hardware Switching Tables
Interpretation of the command string characters:
En-- echo mode; n IN [0..3); selects echoStyleStd (default), ...FD, ...BD, or ...Fwd
F -- T/R lead reversion
G -- A/A1 hookswitch control reversion
H -- Assert Telewall hookswitch
I -- Assert A/A1 to Telewall
J -- Assert Telewall hookswitch, maybe (depends on boolean variable)
L -- Lights led
R -- overrides volume control for ringing through speaker
S -- enables telset sidetone
T -- spMode; configures codecs for electronic trunk action
Xij -- connects crossbar input i to output j
Mn -- voiceMode; n IN [0..2); selects program O3I1 (default), O2I2, or O1I1
Z -- Resets hardware and crossbar
Crossbar Connections:
Port	Input	Output
0	dec1	co1
1	Xmtr	Rcvr
2	from Telewall	to Telewall
3	mike	speaker
4	silence	DTMF receiver
5	dec2	co2
6	line 1 out	line 1 in
7	line 2 out	line 2 in
