Hello 

I'm running on UBUNTU server 10.04 since few days I'm trying to use this
modem :

ID 047e:2892 Agere Systems, Inc. (Lucent) Systems Soft Modem

I've tried to install the agrsm driver using the tar.bz but I'm still
blocking by this :
"Pas de règle pour fabriquer la cible « kernel/bounds.c », nécessaire
pour « kernel/bounds.s ». Arrêt"
so I've tried to use the deb file (agrsm-11c11040_20091225_i386.deb) and
the install was made. 
I've modprobed the two modules agrserial and agrmodem without error and
the devices /dev/ttyAGS3 and /dev/SAGR were created.
It should be fine for the moment..
When I try :
sudo wvdialconf 
I've this answer :

pem@passerelle:~/Modem$ sudo wvdialconf

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?
