That doesn't happen by definition. The primary node directs the secondaries
as to when they may communicate. So if one secondary has been granted
access to the line, the others will not communcate on that line until directed
to do so.

Also be very very aware that EIA485 (RS means recommended standard, EIA is
a actual standard) doesn't have any data link layer, so any communications
protocol you want to use you'll have to implement yourself.
