Thanks so much for the response. Here is some additional information.
I'm trying to emulate an RF network where there are colisions (e.g. "Aloha"
type protocol) so I actually need collisions! I had forgotten that modern
hardware
essentially eliminated them. So, lets say I can find/use an "old hub",
can I control the number of retries? Maybe I have to find some old NICs and
old drivers?
That would be very NIC specific. Retries are done in NIC hardware as far
as i know.
All you need to do to get some collisions is to set the rates to
half-duplex on both sides (hubs were half-duplex). Hubs with lot's of
traffic between other hosts would definitely produce more collisions.
Modern hardware didn't eliminate them. Full-Duplex medium did.
There is a broad range of full-duplex RF systems too :)
