One time support for gnokii:


There are several ways to connect your phone to the computer. Unless you have some kind of wireless connection (infrared, bluetooth), you will need a cable to use gnokii.

The best option to know which cable to use is to refer to the phone's manual. You should find there the information about the accessories. The same information you should find on the vendor's website.

Note, that some phones don't have vendor's support for the cable connection. The example is Nokia 3310. You can still connect it in non standard way (under the battery there's a connector that you can make use of).

As for Nokia phones, there are few types of cable that you might want to know.


This is very old cable type and you should use it only with old phones. The last series that made use of it were Nokia 6210/7110. The only supported protocol by these cables was FBUS.


This is DAU9 extended with AT mode.

Next cable types are so-called Pop-Port(TM) cables.


DKU-5 has a chip in it to emulate a serial port through the USB connector. This is for phones without native USB connectivity. DKU-5 is used for models WITHOUT external memory (6100, 3100, 3120, 3200, 3220, 6610, 7210, 7250, 68xx, 6200, 6220).


DKU-2 is a straight passthrough cable, no chips or logic in it whatsoever... just wires connecting the phone connectors to the USB connector. This works for phones with native USB connectivity. DKU-2 is used for models with external memory (6620, 7610, 6630, 3230, 6230, 668x, 9300, 7710, 9500, 3200).


CA-42 is a replacement cable for DKU-5 cable. Some phones are compatible with both of them, some with just CA-42.


CA-53 is a replacement cable for DKU-2 cable. Some phones are compatible with both of them, some with just CA-53.


CA-70 is a replacement cable for CA-53 cable. Same rules as for CA-53 apply here.

For gnokii support for these cables see our wiki pages.

If you'd like to try making your own cable, this website has some good information.

If you'd like to buy one ready made, here are some places to try.

For sure you will find something also on internet auction sites like eBay.
