That is impossible for random data, unless an extra FIFO buffer is used externally to TWSocket. Trying to understand how TIcsBufferHandler works, it appears to be multiple 1,460 byte blocks (TIcsBuffer), with new blocks being added if data can not be sent sufficiently fast. So I guess the answer to my question is there is no flow control and the buffers will just keep growing if data can not be sent fast enough, until the application runs out of memory.
