It was surprise for me that I could not build PPP with CYGDBG_LWIP_DEBUG: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000719 Then I built it. It ran, my tweaks no break input. I'm sorry, I have no time this sunday to set up host side PPP things. Instead, I write a memo what I done _exactly_ when I tested SLIP. Perhaps, the next weekend, I'll get and PPP memo, but, I wonder, is eCos lwIP PPP worked without the dances before?
