[ECOS] TCP socket problem : connect and bind

["Thierry Brémard" <bremardt@esiee.fr>]

Hello, I have the code folowing , it works fine under a cygwin
environement, it compiles fine with the ecos tools and I load it fine
on my viper card.

after a 'load -v -m ymodem'
I run: 'go'
and I have an error of connect() and of bind().

Furthermore I can ping the viper card thanks to my computer, but the
command 'ping -n 3 -h 1.1.1.2' doesn't succeed on the redboot
environement (where 1.1.1.2 is the ip of my computer), my computer is
linked with a ethernet cable to the card directly.

=> is there some functions to call before using the network ?
in my repository I have an ecos environnement build arround the 'net'
package.
