You don't.

The exception is raised in the context of the listening thread, yes.
Since it is private to TIdCmdTCPClient's internals, you don't have any
access to the exception, or even to know when the thread is terminated
because of it.

The box only appears during debugging, regardless of how your are
running the code. The debugger is displaying a raised exception.
There is no such box displayed when running outside of the debugger.

Then you are out of luck, as there is no event available right now for
handling exceptions on the connection. Unless you write to the
connection periodically and catch the disconnect exception from that.
