As above, the letters (A..H) indicate the lanes, beginning at the lane opposite the
wires if normal direction is selected. The race times are displayed after the lane
designator using the number of decimals selected with the od command. The race
placement character is displayed next.
If some cars did not go through the finish line before the ra command was sent then
the finish line will send back 9.999 for each car that did not finish and the placement
character will be a space.
The result string that is sent back in DTX000 mode is as follows:
1 0.8984 2 1.2326 3 1.3283 4 1.5339
The placement is determined by the order in which they are returned. For example,
2 1.2326 1 0.8984 4 1.5339 3 1.3283
