Hi Gregor

Michal's bug fix. In lcpin.c:

Plus in pppc.c, I've made some changes as follows to use devAhdlc, 
instead of devUsart0 (or devUsart0):

//#include <dev/uartavr.h> /* NCL commented this out */
#include <dev/ppp.h>
// PPP device settings.
#define PPPDEV      devAhdlc0   /* NCL: re-included this line, Was
				commented out. Use HDLC driver. */
//#define PPPDEV      devUsartAvr0    /* NCL removed this line.
					Use standard UART driver. */

I'm connecting directly to a Windows 2000 professional server, so I 
needed to make some changes to some of the handshaking options. In a 
command window on the server type:

netsh
ras
del mult mul
del mult bacp
q

The above stops Windows from trying to negotiate multilink and BACP 
protocols, which Ethernut can't deal with.

And in the incoming connections properties under 'network and dial up 
connections', go to the 'users' tab and uncheck the 'always allow 
directly connected devices to  connect without providing a password'. 
This makes Windows try to negotiate PAP for authentication, which the 
Ethernut needs before it will proceed to establishing the PPP phase. It 
means that you must have the appropriate user and password set up on the 
Windows box.

Of course, the above don't make any difference if you're not using 
Windows as the server, and I suspect it's different if you're connecting 
by modem. I've also got a setup for direct connection to a Linux box, if 
you're interested in that.

Good luck, and thanks to the Ethernut people for all their hard work...
