A method of setting up data communication with a communication means and furthermore program modules and means therefor

The invention relates to a method of setting up data communication with a communication means (TERA), a first (TERA) and a second (TERB) communication means therefor, set-up program modules (PMPA and PMPB) therefor, a test means (CK) therefor and a test module (PMCK) for a test means. The first communication means (TERA) possesses at least one protocol module (P11A, P21A and BA) for data communication via at least one first layer of a communication protocol. The second communication means (TERB) sends a test means (CK) at least one target protocol property of the at least one first or one second layer of the protocol for data communication with the first communication means (TERA). The first communication means (TERA) sends the test means at least one actual protocol property of the at least one layer, able to be processed by the at least one protocol module (P11A, P21A and BA), of the protocol. The test means compares the at least one actual protocol property with the target protocol property. After this, in manner dependent on the respective result, the test means sends the first (TERA) and/or the second (TERB) communication means an instruction for the execution of a subsequent action.
