Oh, that's what i was looking for... thanks.

I'm very new to all this, and it seems like i overloaded myself with 
information, and began to lose details. ( next time i'll read more 
carefully, and will not use lame excuses like this :) )

However, the good news is that i made some progress and now i can talk to 
the 3G card! The tty code is still a mess, (well, not only the tty code 
is a mess :) ) and i can't start PPP session yet, but issuing AT commands 
and getting response from the card works!

P.S.: For those not reading the whole thread[s], this is my attempt
to port the linux (Nozomi)[1] driver for the latest generation of 3G 
(HSDPA/UMTS/GPRS) PCMCIA cards made by Option (also branded as Vodafone 
Mobile Connect) to FreeBSD.
