ABSTRACT:
A method for exchanging information between a first device and a second device connected via a communication link, the communication link supporting a query command and at least a further command, where each command includes a specific command code is described. The method comprises transmitting a query command code and data from the first device via the communication link, the data identifying a specific command, receiving the query command code and the data at the second device, transmitting reply data from the second device via the communication link, the reply data including at least a first segment and a second segment, and receiving the reply data at the first device, wherein the first segment includes information whether the specific command is supported, wherein, if the specific command is not supported, the second segment includes information identifying an alternative command to the specific command.
