Monitor the reading?

Hello
I ma using Indy9 and I need to implement something like a progress indicator
for reading operations.
For example in the client application I have

idTCPClient.ReadStream(ms, DataSize)
Sometimes however data to be read is large (and or takes long time to be
read) and users need to see at least how many bytes are read so far.

Is there a simple way to implement this with Indy and how?

Thanks
