The 6230i uses the Series 40 software platform. It is tricky to connect to. In theory a lot of tools can handle this phone.
I use a DKU2-USB cable to connect the phone to GNU/Debian Linux. gnokii is the only program that actually works with the phone. My configuration is (~/.gnokiirc):
[global] port = /dev/ttyAMC0 model = 6510 initlength = default connection = dku2libusb use_locking = yes serial_baudrate = 115200 smsc_timeout = 10 [gnokiid] bindir = /usr/sbin/ [connect_script] TELEPHONE = 12345678 [disconnect_script] [logging] debug = off rlpdebug = off xdebug = off
If you connect the DKU-2 USB cable with the cell and your USB port the cell is asking you if you want to use it as a USB memory stick. If you say 'yes' it will register itself as a standard memory stick on /dev/usbX. If you say 'no' the cell registers as a modem/cellphone on /dev/ttyAMC0 and you can use it with every program that can use a modem or connect to a cellphone.
