<DIV style="FONT: 10pt arial"><B>Subject:</B> [DUG] Indy Sockets - How to
Receive Asynchronously</DIV>
<DIV><BR></DIV>I have a situation where I need to communicate with a
communications server using Indy TCP sockets. <BR> <BR>After
sending the command the server returns an "OK" response with a second or two
to acknowledge the acceptance of the command, however the reponse from the end
device (returned via the server) may take several minutes to eventuate (or a
else the sever returns a timeout message). I need to be able to buffer
the responses, be aware of when new strings arrinve, and carry on with other
tasks. This threading aspect shouldn't be an issue as I understand
that Indy is naturally multitrheaded by design.<BR> <BR>I'm not familiar
with using the Indy sockets and since there's no "received data event" (due to
the nature of the design) I'm wondering how I capture the asynchronous
responses sensibly?<BR> <BR>Does anyone have some code to show me how to
use the Indy 10 TCPClient component in this way (for the receive part)
? Its probably pretty simple but I need to get my head around it
quickly.<BR> <BR>Thanks<BR> <BR>Eric<BR><BR>
