Is there any API documentation available for the new SmartSDR Serial Passthrough?

    I don't think the API has been updated. There are only a few relevant ethernet API changes. First, setting a usb cable type to passthrough:

    usb_cable set <serialNumber> type=passthrough

    Then SmartSDR CAT interacts with the data by receiving base64 data (by default) from the USB Cable via status message from the radio:

    usb_cable data:base64 <encoded string>

    And sends data from the local virtual port to the radio:

    usb_cable write <serialNumber> base64 <base64encodeddata>

    Hopefully that answers your questions. We will get this updated in the API soon (logged in our system as SMART-11468).

    Hi Christian, I don't think any new API documentation has been released in a while.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
