[ECOS] Problems with ppp and Windows

[Øyvind Harboe]

I've run out of food and drink. This will be my last note in my log :-)

- the problem is that accept() in the attached application does not wake
up until I kill the telnet process. I'm pretty confident that this app
is correct, because it works when I compile and runit from CygWin.
- Debugging TCP/IP is really difficult without an in depth knowledge of
TCP/IP and the freebsd stack. However, I believe that accept() should be
awoken by the invocation of soisconnected() from tcp_input.c since this
is what happens when I kill the windows telnet process. I don't know
what the significance, if any, it is that TCPOPT_CC is not received and
hence a "3 way handshake" is to be used instead. 
- As near as I can tell, Windows believes it is connected, because I
receive packets in my eCos application for the text I typed into the
telnet session before I kill the telnet process.
- I've submitted various patches lately in this regard, but nothing
earthshattering.


Attached: echo.c CygWin/Linux echo app. Same code gets stuck on accept()
w/PPP, Windows PPP server when running under eCos.
