-------------------------------------------------------------------------
Sub Process_Globals
Private sp As Serial
Private astream As AsyncStreams
End Sub

Sub AppStart (Form1 As Form, Args() As String)

sp.Initialize("sp")

Log(sp.ListPorts)

sp.Open("COM3") '*** COM PORT ***
sp.SetParams(9600, 8, 1, 0) '*** BAUD RATE ***

astream.Initialize(sp.GetInputStream, sp.GetOutputStream, "astream")

End Sub

Sub AStream_NewData (Buffer() As Byte)

Dim LogHeader As String = DateTime.Now & " " & Buffer.Length & " :"

Dim LogBytes As String = ""
For I = 0 To Buffer.Length - 1
LogBytes = LogBytes & " " & Buffer(I)
Next


Dim LogString As String = BytesToString(Buffer, 0, Buffer.Length, "UTF8")

Log(LogString)
End Sub
