yeah
its all sorted now. Thanks.
The
only thing I am having trouble with at the moment is, I need to output the HEX
to a comport, and I am using ther ASyncPro comp. from Turbopower, but, it only
seems to output strings.
Anyone
know how I can output the hex data via the Asyncpro comps?

06 = 06
+07 = 0d
+01 = 0e
+73 = 81
+01 = 82
+00 = 82
and the other thing with keep
the base byte means that at the end just make a (mysum and $ff to keep the
first 8 bit).

I
am pulling my hair out here at the moment.
I
have this line of data :-
0df20a0a02450231384301000a
Its
a hex data. Now the last 0A is the checksum.
The
document I have says that the checksum is made up of the SUM of BYTES for these
values :-
0a
0a 02 45 02 31 38 43 01 00
and
this line of data has a HEX checksum of 82 (thats 82 in HEX)
But
I am stuffed if I can work it out. I thought I had it figured out, but NO !
Can
someone enlighten me how to come to these values? I am SURE I am meant to know
this, but its sure as hell not coming to me.
