Re: [microblaze-uclinux] PPP ability question.

[John Williams <jwilliams@xxxxxxxxxxxxxx>]

Hi Pavel,

ppp is very frequently discussed on the general uclinux-dev mailing list
- it seems to be something that people commonly have trouble with.

Can I suggest that you search the archives thoroughly and read the
previous discussions?

Googling "uclinux-dev ppp" would be a good start.

Cheers,

John
