I made a loop until Lof(buffer) and the "\n" are not taken same as the
ascii u mentioned, but this its minor problem that i can deal later

this is a very important info that i never take in consideration!
that's why i always see in console the number "2", due the string
always have the STX at begin of the buffer.. ..

So i can made a loop, that prints/add each converted char to a new
variable.. but i tried it to made a llop :
a) until Lof(Sport) but due data comes something > 8 bits i got two
times the event _Read() so i must change to retund each char..
b) i cannot (or i dont know how) return each char, so i return the
complete string, but dont work
c) try with a while until Len(buffer) but dont work! due the event
_Read if the data comes with 8 bits reach two times

> Message.Info("Character '" & myString & "', ASCII code: " & Asc(myString))
i ask if can made a function to convert each result? by example:
1) the event _Read only returns the string
2) a function that received only when the _Read event will reach with data
3) the function only load a string if are data until receive the ACK
or NOK ascii
umm but right now i not have idea how in a subfuction trap the _read event...

respect that i mail private to you for more specific info and feedback
