The RARP packet type needs to be registered with the packet driver.
You need to add code like this to ./enet/packet.c:

------------------------------
In function pketopen:

...
   if((rarp_handle = pkt_access_type(address,IT_ANY,0,rarptype,sizeof(rarptype),pkt_receiver)) == -1) {
        sprintf(buff,"Can't Access RARP handle\n\r");
        vprint(console->vs,buff);
        pkt_release_type(ip_handle);
        pkt_release_type(arp_handle);
        return(-1);
   }
...

In function pketclose:

...
   if(!slip_mode) {
           pkt_release_type(arp_handle);
           pkt_release_type(rarp_handle);
   }
...

where:
    static char rarptype[]={0x80,0x35};
