Cisco 2600 setting speed 10 duplex half

I have a cisco 2600 configured and working.
I noticed that on my switch Cisco 3524 that it is always negotiating the port.
I am capable of configuring it on the 3524 but am stuck as to what comand line to enter when on the 2600.

I have done the following tell where I am wrong?
config t
interface ethernet0/0

I then have typed the "?" for help but do not see anything that applies.
I have also found other listings at EE they say mode..... I do not see mode as an option

You can't change the speed/duplex on those 10mbps ports.

Go figure. :-)

Depends on the version of IOS that you have. Obviously, your version does not show the half-duplex command.
Ergo, your 2610 interface is 10Mb, half-duplex only. As long as the swtch interface correctly negotiates, then all is well. If you want to hard-set the switch, set to 10/half

I hard set the switch (Cisco 3524) to 10-half and it still negociates (turns orange then back to green) about once a minute.
I know this is a problem because if I configure my computer to go directly through the internet cable modem surfing is much quicker.
Do you have the option to upgrade your IOS?  If you upgraded into the newer IOS's they support the command set you are looking for.  Then you could hard code it to 10 half on the 2610 side of things.  One of our 2621's connects to a 3rd party 2610 and they ran across the same issue recently.
