Dear Friends

This function bufferize the character arrived on serial port.
But when Rx_Char = chr(0) nothing is add to Buffer variable
How I can resolve it?
Thanks

Do
If Ischarwaiting() = 1 Then
Rx_char = Inkey()
Buffer = Buffer + Rx_char
Print Asc(rx_char)
Print Buffer ; " Lung= " ; Len(buffer)
Rx_char = ""
End If
Loop

Hi,

Zero (null) is used for the termination of the strings.
To receive a byte with value 0 you must use a byte array, ISCHARWAITING and INPUTBIN.

Best regards,
