Merve,

Your modulation type and other settings will depend on the command
line options you used when you ran the program (if you try the -h
switch you will see the list of them).

By default, your packets consist of the current packet number masked
to 8 bits and repeated for the length of the packet (" data =
(pkt_size - 2) * chr(pktno & 0xff) ").  You can specify sending
particular packets using the file option, again, have a look at -h.
