You mean download the latest OpenBSD from www.openbsd.org and use their
UDP/IP?

Yes, it is distributed under GPL. You can find it at

Thanks for your answer,

The .h files are already included in the eCos net-package so I think I will
use them. 

When reading the PPP-RFC the Link Control Protocol (LCP) seems to be a big
part of the concept. But maybe I can leave it out anyway?

When browsing the ppp files I also found a "deamon" named pppd. Anybody out
there who has any suggestions on including pppd, lcp,ncp etc?

Hello:

> I don't think I need all the features shipped with the stack just UDP/IP.

I've found recently some information that may help you. Visit the on-line
magazine Embedded Systems Programming (www.embedded.com).  Under Internet
Appliance Design get into Internet Appliance Archives. There you will find
some interesting articles related to networking with embedded systems. Read
"TCP/IP or not TCP/IP?" (April, 2000) by Michael Barr. He had planned to
develop an embeddable UDP/IP stack through a series of articles (code will
be available also).

Hi,

I'm a student working on the LAN Access Profile as specified by the
Bluetooth specification on my AEB-board.

Now when Bluetooth is up and running I need to add PPP on top of that, then
UDP/IP.

Bluetooth simulates a serial cable so I hope there shouldn't be that much to
change.

According to my understanding there is no PPP included in eCos yet, so my
question is:

Where to get it and if someone got any hints on where to start the porting?

I was thinking of using the TCP/IP stack included in eCos over PPP.

I don't think I need all the features shipped with the stack just UDP/IP.

Someone got any hints on what files I need and how to get the stack running
over PPP?

Any help would be appreciated,



Andreas
