Just at a guess this might be a winmodem type of problem.  
I looked at the support site and found that there's a 
substantial driver to download that only supports recent
MS products.  

I have an older cdma modem from AnyDATA and found it useless
for most OS including OBSD.  I was only able to get 
limited tty connections and any crypto bombed it.
