Flow control issues with Windows Sockets

I have a WinSock application through which I do ZMODEM file transfers to a
Linux box. Small files transfer fine. Larger files (> 100K) always fail. The
remote requests resends but never confirms the resent data.

This "looks" like a flow control problem. Is that possible with Winsock?
Doesn't the send() command block if any intermediate buffers are full?

Any thoughs on what could be causing this problem would be appreciated.

Thanks!

I'm not sure that it's winsock problem , because we download/upload files
much more than 100k ( multimedia e.g. ) in Internet Explorer with use
winsock :)
