This (dutch..) site provides some TAPI patches for Wine that are not in CVS: http://home.wanadoo.nl/wijn/girotel/
Since I'm dutch, I'd thought I'd explain a bit on what this site says. Wijn is dutch for wine by the way .
The site explains how to patch wine in order to be able to use girotel software. Girotel is a telebanking system using dail up by modem that was quite popular a few years ago. Anyway, now-a-days most people use Internet for telebanking, not dail up modem. Although the site for that specific bank is not mozilla compatible , it can be used from Konqueror.
The patches seems to be specially suited in order to use this Girotel system.
