3.2.3 ol[#]<cr>:Set/Read lane character

This command sets the character sequence type that will be used to indicate

the lane numbers in the response to the ra, rg and rp commands. The lane

indicators sent in response string will be subsequent values of the same sort such as

upper case letters: A,B,C,D,E,F,G,H (Depending on how many lanes you have.)

ComputerFinish Line

Sends

ol<cr> Reads current character type(A,1,a) from unit.

Description

ol0<cr> Set to A; Upper case letters for lanes

ol1<cr> Set to 1; Numbers for lanes)

ol2<cr> Set to a; Lower case letters for lanes

ol3<cr> Set to A; Upper case letters.

The option settings are given with the following reasoning in mind. Generally

you will want to select a lane number and a place indicator that are compatible but

not the same. If you choose to set the lane character to upper case letters using the

ol0<cr> command it would make sense to use the op0<cr> command to set the

place indicator to lower case letters. These are the settings that we prefer to make

the parsing of the string more dynamic. You would be able to scan the line and draw

out the race time more easily if the upper and lower case letters are used. The

ol3<cr> is offered as a paired value with op3<cr> that will set the lane to upper case

letters and the placement character to the !”#$%&’( sequence. (The hex values for

this sequence begin at 21H). You may, however, set these values to any

combination that you prefer.
