Hello,

Well, perhaps it's my assumption, but I thought that the SIMPLEX message
on the ed0 driver from ifconfig means half-duplex. Am I wrong here?

I assume the hardware is set to half-duplex because in windows it was when
I switched the driver from full to half-duplex that I got a big
performance jump.

I don't know who I would set one or the other either. the ed(4) manpage
talks
about flags to set 8/16bit modes, transmit multibuffering, and using AUI
as
default.

Thanks,

Mark V. Bermal
