By not using ReadLn() at all. You will just have to manually scan
through all incoming data that arrives. I gave you an example of
exactly that in the "How to set the listen port for the TIdTCPServer?"
discussion in this same newsgroup.

ReadLn() removes the returned data from the InputBuffer. If you do
not buffer it yourself somewhere else, then it is gone forever. The
example I gave you earlier leaves the data in the InputBuffer until it
is actually ready to be extracted.
On the other hand, since you are using ReadLn() with a timeout, when
it returns an empty string, and the ReadLnTimedOut property is set to
True when ReadLn() exits, then no data has been extracted from the
InputBuffer yet, so it will still exist when you call any of the
reading methods again at a later time.
