Indy works blocking only
Use ICS instead, they work blocking or non blocking.

Subject: [DUG] Indy Sockets - How to Receive Asynchronously
I have a situation where I need to communicate with a communications server
using Indy TCP sockets.
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.
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?
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.
Thanks
Eric
