Manually setting ethernet speed and duplex

Started by Marco Menchise December 12, 2005
Hello,
I need to test performances of a RCM 3200 sending UDP datagrams on a
LAN. In order to make those tests I need to exclude autonegotiation on
the Ethernet, and manually set parameters like speed and duplex.

How to do that? Any document to read for better explanation? My RCM3200
mounts an ASIX AX88796 as Ethernet controller.

Thanks,
Marco



OK, I have a question.

Has anybody completed the on-line access of a RabbitWeb system to the national time clock services to retrieve the accurate time and date information to use in a data log?

I would like to use this method instead of trying to keep up with the time and date for event logging.

I have used the nisttime.c example to get date/time information from the NIST server.
