Note that when you are placing a TLTcp component on a form in the form
designer then it will by default already have an eventer but it will
be a very special class of eventer that is deeply tied into the LCL
and generate its events from within the GUI event loop, you cannot
call CallAction on this class of eventer. To make your own event loop
you have to create a TLSelectEventer (or a TLEpollEventer on unix
systems or a TLBestEventer on all systems) yourself and assign that
eventer to the TLTcp. From then on you must use CallAction() in your
own event loop. If you create a new TLTcp instance yourself (like in
my above example) it will by default already have a TLBestEventer
(either select or epoll) already created and assigned by default.
