Abstract
A method of providing data communication services between an external electronic device such as a personal computer which is connected to a communication device such as a mobile phone, comprising the steps of: periodically checking a connection state to generate connection state data, storing said connection state data in a memory, and determining whether to provide said data communication services according to said stored connection state data. A device for performing the method is also disclosed.

7. A method of providing data communication services to a communications device based on a connection state between said communications device and an external electronic equipment, wherein said connection state is separate from said data communication service provided to said communication device, comprising the steps of:
-
setting a data flag indicative of whether said connection state between said external electronic equipment and said communications device is normal;
determining whether call data received by the communications device indicates whether said data communication services are being provided;
retrieving said data flag when said call data indicates said communication services are being provided; and
determining whether to continue providing said data communication services based on said data flag. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A mobile phone for transceiving data communication services and for separately communicating with a computer, comprising:
-
a universal asynchronous receiver transmitter (UART) for receiving data from the computer;
a memory for storing a data flag representative of whether a connection state between the UART and the computer is normal; and
a processor for checking the connection state for setting the data flag according to the connection state, and for determining whether to provide data communication services to the mobile phone according to the state of the data flag. - View Dependent Claims (16, 17, 18)
