Kandy and Eriksson's gsm

I think that some of you might know if Eriksson t65/t68 gsm works with Kandy. 
I tried it, but only message is "cannot open device /dev/ttyS0" (same message 
for me nd root.)
I'm usually online with gprs with my laptop using another software (Mikko 
Rapelli's) and it works. I'd like to use Kandy to sync phonenumbers etc... If 
it is possible.
