Fwd: UDP packets blocks

Hi Bob,
thank you for your help.

I'm programming on dBUG, so I use OpenTCP stack implementation...so I'm very
unlucky!

Only one thing: there isn't a function tha can re-initialize tcpip engine?or
some functions that can directly inspect incoming TCP buffer without
callback calls? I find OpenTCP documentation, but I suspect that version in
SBCtools is customized for dBUG

thanks  lot.
Mauro

Whoever can help you will need to know what TCP stack you are using.

May I ask if you are programming for a dBUG/OpenTCP target or a uClinux
target? If the latter, then you need to direct your question to the
uClinux-dev mailing list:

[email protected]
http://mailman.uclinux.org/mailman/listinfo/uclinux-dev

You will want to provide more background, such as the uClinux version,
target, etc..

If you are programming for a dBUG/OpenTCP target, the news is not so good:
There is little or no support for OpenTCP any more. Because of this, we need
to think about adapting lwIP to Coldfire/dBUG targets ..and that is a BIG
job ..but lwIP has an active and supportive community.

Bfn,

Bob Furber
