B4R Question Send ASCII chrs

[Mostez]

Hello,
how can I send ascii (2) and (4) characters to async stream, not "2" and "4" (ascii 50 and 52)

Thanks

AStream.Write(Array As Byte(2, 4))

Tip: Use B4RSerializator. It will be simpler to send complex messages.

How to send the end of the line?

    If Buffer ="setup" Then
        ser.Write("__________")
        ser.Write("pu - pokaz ustawienia")
        ser.Write("cxx - czas czujki")
    End If

I have result in serial terminal
"__________pu - pokaz ustawieniacxx - czas czujki"
I wish that it was so
__________
pu - pokaz ustawienia
cxx - czas czujki

How to do it?

Test with

astream.Write(ArrayAs Byte(10))

Ok I find https://www.b4x.com/android/forum/threads/downloading-a-web-page-with-esp8266.70570/

And write

    If Buffer ="setup" Then
        Dim eol() As Byte = Array As Byte(13, 10)
        ser.Write("__________".GetBytes)
        ser.Write(eol)
        ser.Write("pu - pokaz ustawienia".GetBytes)
        ser.Write(eol)
        ser.Write("cxx - czas czujki".GetBytes)
        ser.Write(eol)
    End If

Working fine

__________
pu - pokaz ustawienia
cxx - czas czujki

example ??

Well, I've attached the code before

astream.Write(Array As Byte(10))

--> ascii 10 = LF (LineFeed)

Not Tested..

If Buffer ="setup" Then
        ser.Write("__________")
        ser.Write("pu - pokaz ustawienia")
        ser.Write(Array As Byte(10))
        ser.Write("cxx - czas czujki")
  End If

how could i define this string in a variable(I need to include the character chr (34))
AT+SAPBR=3,1,"Contype","GPRS"

this definition marks an error in "\"
Private SAPBR As String= "AT+SAPBR=3,1,\"Contype\",\"GPRS\""
