I'm creating a Windows service that uses Indy's TIdTCPServer and
TIdTCPClient. TIdTCPServer and TIdTCPClient are configured to use different
IP addresses.
My TIdTCPServerExecute(AThread: TIdPeerThread) method processes incoming
messages and sends out ACK's and NAK's to a medical instrument over our
company network. The communication is half-duplex. Only one side can talk
at a time. When there are no incoming messages being processed, I want my
application to send one or more messages to the medical instrument using
TIdTCPClient. This will involve sending a message and receiving an ACK or
NAK from the medical instrument.
I'm assuming that I have to stop the TIdTCPServer from listening
(TIdTCPServer.Active:=false) before I startup the Client with
TIdTCPClient.Connect(). However, I don't see a TIdTCPServer property that
tells me that the TIdTCPServer is inactive (no active threads). Is there a
way to tell that TIdTCPServer has no active threads processing incoming
messages? I don't want to set TIdTCPServer.Active to false until all the
active server threads have finished.
