SendCmd() receives the response from the server and puts it in the
LastCmdReply property for you. You should no need to read a line manually,
unless your server's replies are not being formatted corrected.

Because Indy thinks you are still connected to the server. You can only
connect once at a time. What is likely happening is that you are not
reading everything the server sends you, so the IOHandler's InputBuffer is
not empty. Indy considers a connection to be active if reading operations
can still be satisfied. You are probably also using an older version of
Indy 10 that does not clear the InputBuffer when making a new connection.
