Assist an on-site serial session remotely

Scenario 7: assist an on-site serial session from a remote browser

Use Cloud Console when a device is attached to a computer at another location and a remote engineer needs to inspect live traffic or guide a short diagnostic session without exposing a TCP port or installing a virtual COM driver.

1. At the device site, confirm that Serial Port Utility can open the port and exchange a known request locally, then sign in to the account that the remote engineer will use.
2. Enable Cloud Console on the desktop but leave Allow Remote Send and Allow Remote Port Control off for the first view-only check.
3. The remote engineer signs in at alithon.com, opens Cloud Console, selects the online computer and then selects the target port. Allow up to about 30 seconds for the first live events to appear.
4. If a diagnostic command must be sent, the person at the device temporarily enables Allow Remote Send. Enable Allow Remote Port Control separately only when the remote engineer must open, close or reconfigure the port.
5. Send one known command, confirm the command state, and verify the device response in the following RX log. A succeeded command alone does not prove that the device answered.
6. When the session ends, turn the two remote-action permissions off again. Use desktop log files when the investigation needs a complete or long-running record.

Cloud Console is a live support window rather than a recorder: it uploads events only while someone is watching, keeps no traffic history and consumes the account's cloud traffic allowance and top-up balance.
