PCT No. PCT/DE94/00237 Sec. 371 Date Oct. 27, 1995 Sec. 102(e) Date Oct. 27, 1995 PCT Filed Mar. 8, 1994 PCT Pub. No. WO94/22252 PCT Pub. Date Sep. 29, 1994A serial data stream of control commands is sent to a shift register having a delay time corresponding to a shift frequency which is a multiple of the maximum expected bit rate, each control command beginning with a uniform binary character having a start sequence with a maximum duration. The bit rate is calculated from the duration of the start sequence which is measured by activating a counting circuit during the time in which the data stream is passing through the shift register. The bit rate is programmed into an integrated serial data transmission component, preferably a UART, and the delay time of the shift register is determined according to the maximum duration of the start sequence, plus the time required to program the bit rate into the UART. |
