Is there any way to check and see if there are any available
characters to be read from a TIdPeerThread.Connection?  I don't want
to execute a TIdPeerThread.Connection.ReadChar unless there are
characters left in the input buffer to be read.  Does Indy's
TIdPeerThread.Connection.ReadChar wait until there is a character that
can be read from the input buffer or does it return with a null string
if no input data is available?  Thanks in advance!
