Equivalent of get device status in 'serial' to 'serialport'

I am updating some legacy codes, namely changing 'serial' to 'serialport,' as 'serial' will be removed soon.

Part of the code are as follow:

if get(device,'Status') ~= 'open'
    ...
end

According to the serial properties documentation, "Status of serial port device connection, returned as closed or open."

I have been going through the serialport documentation, theres nothing similar to 'status' property.

I wonder how can we handle this check?

Why TMW thinks they have to completely revamp stuff is beyond me...this machine doesn't even have a serial port, but in one of the examples there's the following note: "When you are finished working with the scope, clear the serialport object."

So, I'm guessing it's up to your application to keep track -- perhaps exist() then...make it hard don't they... :(

This is the code I used:

if exist('device','var') ~= 1
    ...
end

More information about the exist syntax here and about the way to use it here.

Kewl...glad the guess turned out to be a fruitful approach...
