Serial receive - order

Hi
Is there a simple way to set the receive order of variables?
Often, a device would send out a <cr> or <lf> that one uses as a marker, but in this case I have no control of the receive string format.
If I send out;
\01\02\03
and I have; \[a]\[b]\[c] as the receive variables
the received variables can be;
abc
123
231
231
312
How can I get an order without sorting the variables in a VB script?
The device I'm using sends a string format that I cannot modify, something like;
55 aa 01 00 01 00
What I would like to do is simply receive the sequence in the order that it come in
\[a]\[b]\[c]\[d]\[e]\[f]
where "a" will always receive the first character, in a similar way to the console window.

Ok, I wrote a simple 'if' script to sort them.
It would have been nice if I could have used something like;
<85> <170> in the same way that one uses;
<lf> <cr>
Ie the parenthesized figures, of choice, determine the string match

Yes, that what
\255\0\[left_motor]\255\1\[right_motor]
in the serial module documentation is referring to. 255 is often used as a sync char which is what you were looking for. So in your case
\85\170
should do the trick.
