* Wait at least 5 ms.
* Wait until transmission of the RS frame has been completed: At an RS
baud rate of 19,200 with 8 data bits, even parity and und 1 stop bit, RS
transmission has a duration of approximately
1.3 x 16 x (11 x 1/19,200) s = 12 ms.
* Wait until the frame has been evaluated by the MIGRA display.
