C-h sends backspace?

[Christian Herenz]

Hi,
I am using an emacsen (Zile) on a remote machine. The problem is, that 
the C-h key (not only in Zile, also in other apps) sends backspace to 
the remote machine. I only find information for the case, that when I 
press "backspace" the Help pops up, cause Backspace sends C-h. What can 
I do, Is it possible somehow to have C-h still as C-h and Backspace 
still as backspace?
Greetz,
Christian
