gnokii is a generic phone tool that happens to work very well with Bluetooth in Mac OS X - provided you know how.
The latest sources compile without incident in Tiger, provided you issue:
./configure -disable-nls
...to remove the dependency on libintl.
To get a phone to work with gnokii over Bluetooth, set your .gnokiirc to include the device's Bluetooth address just like it is displayed in the Mac OS X Bluetooth preference pane:
[global] port = 00-11-22-33-44-55 connection = bluetooth model = 6310i initlength = default # Commented entries for my own reference # port = /dev/cu.Nokia6310i-1 # connection = dlr3p
