Details:
When trying to create serial object in Octave, I got the following error
message:
>> s=serial("\\\\.\\COM15",1200)
error: serial: Error opening the interface: No such file or directory
Nothing I tried would work and I simply couldn't connect to the piece hardware
on the serial port. Until I realised that the port was actually already open
in a PuTTY window.
It would be great if the error message was a lot more helpful, with something
like "Unable to create serial object, COM port already open." or similar. Not
sure if it's possible to detect whether a port is already open when attempting
to create the serial object.
