You should rev the version here by adding something like
M20 = 0.5

[viettrungluu, 2012/04/19 20:19:06]

Since this is decidedly binary-incompatible, you should really increment the
version.

[kmadhusu, 2012/04/20 22:29:57]

Done. Added M20 = 0.6 and also updated interface names in ppp_printing_dev.h
