PCT No. PCT/DE93/00585 Sec. 371 Date Jul. 22, 1994 Sec. 102(e) Date Jul. 22, 1994 PCT Filed Jun. 25, 1993 PCT Pub. No. WO94/02892 PCT Pub. Date Feb. 3, 1994.For operating input devices such as magnetic card readers (22) or keyswitches (23) on personal computers (11), these are connected to the keyboard processor (18) and activated by hitherto unused control codes. The data of the input devices are recoded into data for possible key operations and the data transmission to the personal computer is initiated by the code for a non-existent key. As a result, the keyboard controller in the personal computer does not need to be reprogrammed, and the function of the input device cannot be simulated via the keyboard. |
