nothwithstanding the fact that if length(s)<1 line 444 won't be 
executed, so the "uninitialized" should be flagged in line 442, I know 
that this chunk is inside

procedure TButlerPhone.Receive(s: string);

so s is a parameter.
This procedure is called exclusively from

procedure TStatusThread.Receive;
begin
   FOwner.Receive(FData)
end;

(FOwner is a TButlerPhone)

which in turn is called only here:

           FData:=copy(buffer,i+2,L-1);
           if buffer[i+L+1]=checksum(FData) then
           begin
            if not terminated then synchronize(@Receive);
           end else
