- When reading Inside Mac, you'll be tempted to use the "DDPRead" to
- read the response to your Echo packet. Don't. You'll never get
- any incoming packets. DDPRead was written before MultiFinder came
- along.
-
- You have to write a socket listener (in assembly). See the latest
- Macintosh Technical Notes from Developer Technical Support -- I'm
- pretty sure I saw a complete socket listener sample source code you
- can steal.
