Resize the default window size

Hi,
How can I resize the terminal window's default size in CDE (Solaris)?

Regards,
Sharif.

vi $HOME/.Xdefaults and add ...
Dtterm*<resource_name> : value where the resource comes from those listed in man dtterm

eg :

Dttermforeground:Wheat
Dtterm
background:MidnightBlue
Dtterm*geometry: 80x24

logout and back in again to see changes.
