Error using serial/fopen (line 72) Open failed: Port: COM1 is not available. Available ports: COM9, COM15. Use INSTRFIND to determine if other instrument objects are connected to the requested device. Error using serial/fopen (line 72) Open failed: Port: COM1 is not available. Available ports: COM9, COM15. Use INSTRFIND to determine if other instrument objects are connected to the requested device. Error using serial/fprintf (line 144) Unexpected error: OBJ must be connected to the hardware with FOPEN..
Observations:
  • same errors with attempt to perform exercise with COM2
  • block settings only allow COM1-COM4, not COM9, COM15
  • device manager show COM8, COM9 COM15 in use
Questions
  • Why is COM1 unavailable? COM2?
  • How to make COM1 'available'?
Diagnostic questions are good: actionable suggestions are appreciated. Examples are preferred. *Thank you*
