Re: [ECOS] Sending network broadast packet.

Thanks for you reply.

I've already looked at BOOTP and DHCP code. I can only send out
255.255.255.255 broadcast packet only if my IP address is 0.0.0.0 and
subnetmask 0.0.0.0. Once the IP address and subnetmask are changed with the
actual network IP address and subnetmask, I can't transmit 255.255.255.255
broadcast packet anymore.

For your information, I'm trying to implement a BOOTP server.

Thanks.
