sms sending failed

[JoWo]

Hello everyone,
I'm having a problem sending SMS messages via a USB modem. I've tried it on a SpaceLYnk (v. 3.0.0) and a LogicMachine (20241211). I've also tried various USB modems, but I always get the same error. 

   

The USB device appears in the system log, but it's not listed under serial ports.

   

The SMS script I'm using is from here: https://kb.logicmachine.net/notifications/sms/.

I'm currently stuck for what else I could try.

I would be very grateful for your help.

Which other modems have you tried? It might be possible to update the relevant package so the USB mode change happens correctly but it will only work in LM.
