Too many letters to type to reach the same result. :)

Plus, I like how it reads so that is what I use normally use in all
languages I work with that offer Object based string with inherent
operators.

Just all I did was compile the code and before and after the minor
changes for the PeerInfo stuff and adding a simple echo logic, I used
a simple TTY to connect and type away.

1) After the first 3-4 letters, there was an exception. I believe your
explanation that it assumes a 4 byte packet or whatever explains that.

2) And when exiting the application, the IDE dumped a few leaks.

Let me try it again....

Ok, started the AsyncServer under the IDE, port 13000.

Open a Penalty Box and typed

Telnet LocalHost 13000

typed

HELLO<enter>
ctrl ]
QUIT

The socket closed and clicked EXIT, the IDE output shows:

Dumping objects ->

Object dump complete.


Its odd that it shows that path. I don't see RTL LIB that your binding.

I just also did another thing.

I compiled the AsyncClient and ran it to connect to the AsyncClient.

I connected and entered "hello" in the Send field, clicked Send and
POOF! the AsyncServer faulted. Here is the call stack:
