If someone out there could explain the CommToolbox SendProc sample routine
on page 103 of the manual, I would greatly appreciate it. As it stands
now:
1. What is a WindowP? And where is it declared?
2. Where is the function GethConn defined (assuming it is a function and
not a type cast)? (And all of the other GethXXX routines.)
3. Why is theConn assigned a value only to be
reassigned a different value a couple of lines down?
4. Why is theTerm even there when it is not ever used, just assigned to?
5. Where is flags declared?
Here are some general comments:
1. I have never before needed to pass a pointer to a handle (for example,
in TMChoose).
2. In Think's C, before I would get lots of "Illegal Pointer/Integer
Combination" errors. Now, with the prototypes, I get loads of these
"Call of XXX does not match prototype" or something similar, which is
not very helpful (since I then have to locate the prototype).
3. Why do some buttons have to be clicked? Is there no default on the
return key? (For example, after a connection has been made by the
Modem tool.)
4. A direct connection tool would be extremely helpful.
That should about cover the questions of the last 5 hours. Thanks for any
help you can give.

You got source to our primary test app, which means there's a whole lot of junk in there that's meant to give the toolbox a hard time. Try this one out: FUNCTION TermSendProc(thePtr: Ptr;theSize: LONGINT;refCon: LONGINT; flags: INTEGER): LONGINT; VAR theErr : CMErr; BEGIN TermSendProc := 0; theErr := CMWrite(gConn,thePtr,theSize,cmData,FALSE,NIL,0,flags); IF theErr = noErr THEN TermSendProc := theSize ELSE ; { some error handling here, maybe } END; gConn is a global, or you could use the refCon being passed in (it's the terminal record's refcon) to access it. flags does end-of-message stuff for connection tools. It should be documented a little better in the next manual release > >Here are some general comments: > >1. I have never before needed to pass a pointer to a handle (for example, > in TMChoose).
