Try this article:
http://www.linuxquestions.org/questions/archive/3/2003/09/2/90671

There are a few commands that might work.

Search http://tldp.org for Duplex and see what comes up there.

you could try using mii-tool if it's on your system.

mii-tool -v to check the nic card

And to change settings.

mii-tool -F 100baseTx-HD eth0
mii-tool -F 100baseTx-FD eth0
mii-tool -F 10baseT-HD eth0
mii-tool -F 10baseT-FD eth0

Cheers

Also good is ethtool

Have a look at man ethool, it is a very complete tool also.
