When will Flash magic support com ports greater than 4?
It already does. Please read the Hints and Tips application note:

Thanks and best regards,

Have you read through the Flash Magic application note "what to do when ISP does not work"? If not, please work your way through it as it will guide you to narrow the problem down.
