Tom,
Not yet.
It seems the 'serialkiss' parameter is only for KISS terminals. It doesn't work with a KISS TNC so well. Packets kept bouncing back-n-forth (couple redundant loops).
Terminal to terminal the LoRa devices work great.
For now I've put the LoRa devices on the back burner in hopes DW will accept them as a TNC and assign a Channel number to it.
Good luck
