List USING [Reverse],
Current assumption, subject to change as we develop the notion of multiple calls: Only one call is allowed, by Lark, to reach interesting states (>=failed, +notified).  We can select any call that does go beyond an interesting state, to indicate the "current" call; all actions that deal with ongoing call will refer to that one.  We will not, for the moment, allow any manual selection of conversation-log entries.  When there isn't an entry, it's OK to place calls without hanging up first.  So Lark and FinchTool/Directory know about the one-call philosophy; FinchSmarts does not, at present.

Current assumption:  all descriptions, including called/calling party fields and conversation logs, describe only the first other party; in a conference, they'll ignore late arrivals.

Types and Typeoids

Placing and Controlling Calls

[parent: REF ANY, clientData: REF ANY _ NIL, mouseButton: Menus.MouseButton _ red, shift: BOOL _ FALSE, control: BOOL _ FALSE]
[parent: REF ANY, clientData: REF ANY _ NIL, mouseButton: Menus.MouseButton _ red, shift: BOOL _ FALSE, control: BOOL _ FALSE]
[parent: REF ANY, clientData: REF ANY _ NIL, mouseButton: Menus.MouseButton _ red, shift: BOOL _ FALSE, control: BOOL _ FALSE]
No Conversation ID needed here because assumed not active in any now.
Called whenever the user clicks the answer button
Refers to entries in the viewer finchToolHandle.conversations, not necessarily current one.
Button-invoked operations when applied directly to conversation-viewer log entries.
SelectEntryInConversations[viewer]; -- no manual control over selection!
Called whenever the user clicks the hangup button
Refers to entries in the viewer finchToolHandle.conversations, not necessarily current one.
Called to disconnect a call in progress without logging a message.

Parses single party-specification: phone number (leading character is not a letter), or named recipient.  Names can be RNames or other text sequences that can be looked up in one's private (TDir-style) telephone directory.  "XXX at home" is a request to call a residence rather than office number.  "home" is equivalent to "<logged-in user> at home".  "left XXX" and "middle XXX" are equivalent to "XXX".  "right XXX" is the same as "XXX at home".  This is to accommodate the strange Command Tool. "XXX at <number>" says you want to call the specified number, and the recipient is XXX (not implemented yet.)


Other User Commands

FeepCmd: Commander.CommandProc = {
textToFeep: Rope.ROPE _ FeepValue[cmd.commandLine.Substr[start: 1, len: cmd.commandLine.Length[]-2]];
IF ~CheckActive[finchToolHandle] THEN RETURN;
[] _ FinchSmarts.Feep[textToFeep];
};

Convert an arbitrary rope into characters found on a DTMF touchpad.  '*, '#, and digits and all punctuation (often used to format phone numbers) map to themselves. Letters (either case) map to their standard telephone-dial locations.  Also, 'Q->'7 and 'Z->'9.  One can put a leading '. or something in front of an address to force higher levels to interpret it as a "number" instead of a name.
Now people can dial .FAX or .HELP or 9(800)TheCard, or 9Fastell.
Starting and Stopping
If not active, try to make it active.
Conversation Management

Don't use conversation buttons for failure reports
If we originated, called-party is already set better than we can get this way (home or office, nicknames, and so on.)  Else pick up calling party (incoming), or called-party (outgoing).  originatorRecorded is set TRUE whenever one of these fields is set.
Don't want to step on twiddling if state=ringing.  This call covers hanging up from non-ringing state or placing outgoing call.
If idle, elaborate.
Describe the other party.

Other party descriptions can be of the form "xxx.pa (nnnn)", which confuses Phone commands.  Number in parens and lack-of-authentication question mark should be eliminated from number field being set here.
Other party description can contain Intelnet pause characters and authentication code.
Intelnet pause characters are all characters < '\040, followed by "P".  For the present, we assume that there's a P following the pause in one of these; other values are possible, but we don't expect them in phone numbers.
Should be repaired (pause => "*" and auth-code removed) wherever the user sees it.
IF cDesc.bluejayConnection THEN "Recording service"
ELSE IF cDesc.proseConnection THEN "Text-to-Speech service"
ELSE
Assumes that the ordinary Finch icon is unlabelled.
Viewer Construction and Management

Finch Viewer
Check how much space is left (if any) in the control window for a typescript.
Finch Tool Viewer
MakeOneMenu[finchMenu, "SpeakText", SpeakSelectedProc];
MakeOneMenu[finchMenu, "StopSpeech", StopSpeechProc];
Conversation Viewer
Conversations Viewer

ViewersOps.AddProp[newV, $convDesc, NIL];

Above could be used to forget about any conversation but the latest one.  Once we're dealing with multiple converations, that won't be good enough.  Perhaps a better place to do that is where we detect them going idle.
At present, this occurs only when one had dial-tone or was dialing and hung up.  Otherwise, busy calls would be lost and we some day hope to be able to use the information about busy calls in redialing. STCWN (Subject to change without notice.)

Directory
Viewer and Button Utilities

Creates a text viewer, next right on the same line as sib
 sib must be a Viewer, not NIL
 Make an h-bit wide line after sib
Sib is sibling to create TS after
Containers.ChildYBound[sib.parent, ts];
Reporting and Logging

Registration, Initialization
Register a command with the UserExec that will create an instance of this tool
Commander.Register["SpeakText", SpeakTextCmd, "Utter the remainder of the command"];
Commander.Register["STOP!", StopSpeakingCmd, "Stop speaking"];
Commander.Register["Feep", FeepCmd, "Issue touch-tones"];

changes to: ReportConversationState, SpeakSelectedProc, speakTextFeedbackLen, SpeakTextWithFeedback, StopSpeechProc
Swinehart, September 6, 1985 10:03:45 am PDT
Don't OPEN FinchTool.bcd, eliminate (status line, extra Phone button).
Eliminate dual-menu, demote Drop-Out.  Merge Phone, Redial.
PhoneSelection becomes CommandTool feature, with user profile help.
Add names->feepNum features (can dial 9(800)TheCard)
Add feep command (for talking to your bank or whatever).
Add HangUp, SpeakText, StopSpeaking commands.
Pick up incoming call idents, outgoing calls originated at telset, in called-party fields.
Automatically connect to Server when command is issued; don't delete conversation viewer when disconnecting any more. Reorganize order of procedures.
