The remote station may require a specific feature not available with 
Nut/OS PPP. You need to enable PPP tracing. Add

HWDEF+=-DNUTDEBUG

to app/UserConf.mk _and_ bld/UserConf.mk, replacing app and bld with the 
directory names you configured for the build and sample tree.

In general, this is a non-trivial problem, because initial PPP 
handshaking is complex and greatly differs among access providers.
