ARTX-166 TCPNet: Sending UDP frames to a broadcast IP via Ethernet

Leverkus Volker

Hi,

I use ARTX-166 on a C167 with CS8900 Ethernet chip. Everything works fine, but when I try to send a UDP frame to e.g. 192.168.0.255 (Subnet mask 255.255.255.0), which is the broadcast address, the system sends an ARP request to find the MAC address of the destination instead of using the broadcast MAC address. As there is no ARP reply in this case, my UDP frame is never sent. Does anybody know how to overcome this behaviour?

Thanks in advance

Volker
