How to use Gammu with Wavecom as mOdem

[<ps...@gm...>]

Hello

My English is not good ......

I 'am new user of Gammu,
and  I will use Gammu on my project

I have Wavecom (Wismo WMOD2 Dual band ) as modem and i would like
cconnect it to Gammu using a serial Port RS-232

I use Ubuntu Feisty as Linux kernel

I have download and install Wammu 0.17 - Python-Gammu 0.17 and Gammu 1.09

After that I connected my Wavecom to the serial and edit .Wammu to
configure  Wammu and Gammu  but I can not detect my Wavecom

Gammu send me this message

   """"""""Erreur de communiquation avec le t=E9l=E9phone
