Gert,
That's not exactly true. On a 10mb half duplex connection a collision while
sending a frame will cause the router to back off and retransmit that frame.

The end station will retransmit if the packet is lost or corrupted on
the way. The router will *never* retransmit a packet, except if the
router is also the end station of the TCP connection ("telnet to
router").
