Expansion card

A method for detecting the turning on of an expansion card connected to the expansion card connector of an electronic device and for setting a function mode, whereby the expansion card can be set in at least one of a first function mode and a second function mode, wherein in connection with the turning on of the expansion card, the following steps are taken in the expansion card:

• a signal is generated and transmitted to the electronic device about the turning on of the expansion card,
• the expansion card is set in the first function mode, and
• a message is generated and transmitted to the electronic device about the setting of the first function mode,
• and wherein the turning-on signal and the function mode setting message are received in the electronic device and the following steps are taken in the electronic device:
• selecting the function mode to be set on the expansion card;
• generating a function mode exchange message;
• and
• transmitting the function mode exchange message to the expansion card;
• conducting the exchange of the function mode to the selected function in the expansion card;
• storing information about the function mode of the expansion card in the electronic device;
• forming in the electronic device, in connection with the restart of the expansion card, a message comprising information in accordance with the stored information about the function mode of the expansion card;
• and
• transmitting said message to the expansion card and setting the function mode of the expansion card to the mode indicated in said message.

A mobile station which is arranged to operate in at least a first function mode and which comprises at least:

• expansion card means arranged to be connected to an expansion card connector of an electronic device;
• means for setting the function mode;
• means for connecting the expansion card means to the expansion card connector of the electronic device,
• means for generating a signal upon the turning on of the expansion card means;
• means for transmitting the signal to the electronic device;
• means for forming a message about setting the first function mode;
• and
• means for transmitting the message to the electronic device;
• and further comprising:
• means for receiving stored information about the function mode of the expansion card from said electronic device, which information is in connection with the restart of the expansion card;
• and
• means for returning the function mode of the expansion card in accordance with said information about the function mode of the expansion card.
