I'd not noticed that, I can't resize the window either, locally or remotely.
I usually use the HMC remotely but I don't use the remote terminal function remotely.
If I want the console on an LPAR I ssh to the HMC with putty and then use vtmenu for the console.
It saves loading the WebSM and the console can be resized.
If you've not used vtmenu before, to get back to the vtmenu from a lpar console, exit the shell and then use:
~.
and the console will exit.
