Last change on this file since 4bd8a5b was da34e20, checked in by Shane Alcock <salcock@…>, 15 years ago

dag_read_packet now returns a DUCK packet occasionally in place of a regular packet - changing the DUCK frequency will *soon* be a config option
wag_start and wag_pause will now turn the radio on and off, respectively
Added DUCK structures to rt_protocol.h for use with RT_DUCK_* packets
Updated format_rt to deal with RT_DUCK properly
Removed erroneous free(packet->buffer) when packet is not under our control in format_pcap.
Added check for DAG 2.4 in configure
