I made a quick port with small enchancements from nserver 1.0.0 GPL to backup my data from old Nokia 9110 Communicator.
Nserver allows you to backup, restore, and install to the Nokia 9000 and 9110 Communicator from Linux, *BSD, Mac OS X.
– works on OSX 10.x with serial (usbserial too) ports
– Mac OSX binary attached
– startup script (nserver.sh)
