Hello All,
I'm trying to do this issue since when I had Festy, then Hardy, then now with Interpid, no way...
Now, I followed your step one by one, and what I obtain is:

XXX@XXX-interpid:~$ sudo synce-serial-start
[sudo] password for XXX:
Connect script failed

synce-serial-start was unable to start the PPP daemon!

When I try to:
XXX@XXX-interpid:~$ PPP daemon
bash: PPP: orden no encontrada

Meanwhile when I start from:
sudo synce-serial-start, I get:
samer@samer-interpid:~$ sudo synce-serial-start
Connect script failed

synce-serial-start was unable to start the PPP daemon!


I don't know what bad I'm doing in all this...

I'm trying to connect IPAQ 6915 with WM5

Thanks in advance,

Samer
