Problem connecting the server

Hello I try to import an informix database. (server sco Unix V release 3.2) To do so, I try to connect the server from a windows98 station with the informix obdc drivers. The problem is that I don't know how to get the database name, and where is the daemon. How can I get it? Is there a simple way to import the database? The datas seem to be strored in .dat and .idx files. Is there a way to convert it (we don't know the structure of the database!, so it's hard to use parse delimiters with .dat files ...). thanks per advance
