Since I am running on Linux I can not verify if the code is correct. Anyway, here is a copy of it:

Sub Send_and_Read()
  '--------------------------------------------------------
  cmnd$ = "Hello World"        'A string to send
  '--------------------------------------------------------
  Open "COM1" For Binary Access Read Write As #1
  cmnd$ = cmnd$ + Chr(13)      'add [CR] to command string
  Put #1, , cmnd$              'write string to interface
  '--------------------------------------------------------
  answer = ""                  'clear response string
  char = Input(1, #1)          'get first character
  While (char <> Chr(13))      'loop until [CR]
    If (char > Chr(31)) Then
      answer = answer + char   'add, if printable char
    Else
      ' Do what ever you like
    End If
    char = Input(1, #1)        'get the next character
  Wend
  Close #1
  '--------------------------------------------------------
  Cells(1, 1) = answer         'put response in cell("A1")
End Sub
