Agent does not properly update 'IsOpen' Port State

[montymxb]

Describe the problem

The current version of the agent does not appear to update the IsOpen state of serial ports. This is set to false by default on adding a new port, but does not appear to be updated when a port is opened, or closed.

This is evident with the latest arduino-create-agent-js-client, which checks this value to determine whether or not to actively close the serial port before attempting to upload a new program via serial. Since this is always false, opening the monitor first effectively prevents the client from uploading anything, as it just skips the close step.

The check is handled inside the method that handles closing the monitor, so invoking it directly also has no effect. The user either has to close all ports forcibly, or directly issue a command to the agent.

To reproduce

1. Download the latest agent
2. Connect a board (probably flashed with a program that opens up the serial)
3. Open the 'Debug Console' in the drop-down for the agent
4. Run list & observe the 'IsOpen' property is false
5. Open the serial port using the appropriate args: ex. open /dev/MyDeviceXYZ 9600 timed
6. List again, and observe IsOpen is still false

Expected behavior

As far as I understand (based on the behavior of the JS sdk) opening the serial port to a board should mark the IsOpen property as true, and closing it should mark it as false.

I presume such updates could be performed in https://github.com/arduino/arduino-create-agent/blob/main/serialport.go#L270, and https://github.com/arduino/arduino-create-agent/blob/main/serialport.go#L349, using the current serialPorts.

Hi all, thanks for resolving this quickly. @Xayton @cmaglie any news on when we can expect a patch release to be made available for this?

[Xayton]

Hello @montymxb, we plan to integrate an additional fix, related to the recent "board discovery" changes, and then release the 1.4.1 version. This is expected before the end of the current week.
