That is because there are not supposed to be any events triggered.  Indy is
not an event-based library.  Its operations are synchronous, not
asynchronous.  Simply call ReadBuffer() (or other appropriate reading
method) immediately after calling WriteBuffer().

As well it should be, because that is how Indy is designed to work.  You
called a reading method on the connection, so data is read from the socket
at that point in time, and then passed to the Intercept that you have
assigned to perform additional processing on the received data.

If you think that using a TIdConnectionIntercept will give you asynchronous
events, then that is not how Intercepts are to be used.

Since you are reading a fixed-length structure, I suggest that you use
ReadBuffer() instead of ReadLn().

Indy handles multiple packets internally.  All you have to do is tell Indy
how much to read total, and it keeps reading until that amount is received
in full.  Which means that you have to know ahead of time how much data is
going to be sent - or - know how the data is begin to be terminated.

No, it does not.  Indy 9 is the same in both BCB and BDS.

Only in the context of other reading operation.  Again, Indy is not an
asynchronous library.  You should not be relyiung on events to handle the
connections.

That is because you are not using Indy properly to begin with.
