I'm lost... How much of the code you posted actually works? Does the
string "Test" actually wind up on the LCD?

If you ONLY problem is getting chars from the SP then something like:

dim ch as byte
dim i as byte
dim b as oBuffer20

i = 0 ' buffer index is zero based
do
if SP.Received then
ch = SP.Value 'save the char, we can't come back to SP.Value
SP.Value = ch 'send it back to the PC so it can be checked
LCD03 = ch 'send it to the LCD
b.location = i 'b.location can be automatic (not used)
b.value = ch ' put in buffer
i = i+1 ' update pointer
end if
loop

I have taken the received char and sent back out the serial port, sent
it to the LCD and stuffed it in a buffer. You can choose any or all
of these options and junk what is unnecessary.

Clearly the buffer will overflow eventually, I don't know why you
want to buffer the chars but you need to manage it somehow. You can
use the .Width property to find the highest valid index and, rather
than setting the pointer to i = i + 1, set it back to zero if it is
already equal to the .Width value. If you want a circular buffer...

The code above is 'pseudo' code in that it hasn't been checked. It is
just for reference.
