You don't really need to send a memory stream, since you data is
already in a TStringList.  So just use:

      Client.SendStr (SL.Text);

To send a stream, you read part of it into a buffer, and then send that
buffer.  It gets more complicated if the stream is vary large, since
the above version requires ICS to create buffers for all the data
passed, and you would not want to get a 2GByte buffer.
