Howk,

I use to communicate <Web/Web.h>
win7 and Linux is the communication works.
g = socket(PF_INET, SOCK_DGRAM, IPPROTO_UDP);
int optval = 1;
setsockopt(g, SOL_SOCKET, SO_BROADCAST, (const char*)&optval, sizeof optval);
adr.sin_family = PF_INET;
adr.sin_port = htons(UDP_PORT);
adr.sin_addr.s_addr = htonl(INADDR_ANY);
retx = bind(g, (sockaddr *) &adr, sizeof(adr));
ret = recvfrom(g, frame, sizeof(frame), 0, (sockaddr *) &nad, &ret1);

the compilation of XPsp3 sends a frame the controller sends back but now that recvfrom is not receiving.
or met someone with a problem on the part of XP in receiving the UDP?
Ethereal checked the frame from the driver goes a good frame but unable to recvfrom

I greet all!!
