I think I've mostly got a handle on socket reading, but now I can't
seem to get any data out over the socket.

I've tried Write() and WriteDirect() (with TByteDynArray for the
data), with WriteBufferFlush() and WriteBufferCancel() (the latter
before the write).

Packet capture shows nothing being sent.

How can it be this difficult to simply send data over a socket?

Then you are probably not using it correctly.  Please show your actual code.

Write() will work just fine.  Don't call WriteDirect() directly.

Any particular reason why you keep using TByteDynArray instead of Indy's own 
TIdBytes type?

WriteBufferFlush() does not do anything unless WriteBufferOpen() was called 
first.

Then you are not writing anything to begin with.

> How can it be this difficult to simply send data over a socket?

Because you are using Indy the wrong way, most likely.  Again, please show 
your actual code.

It was a cerebral failure in RawToBytes().  Once I fixed that, it
writes fine.
