Every time my USB modem (/dev/dlinkModem) gets unplugged it defaults to "radio disabled mode" (AT+CFUN:4).

I can easily enough call AT+CFUN:1 through the minicom application console to enable radio again. However, I would of course like to make this an automated task as it sits on my server.

Any ideas?

  • make it work (it's usually called from pppd but doesn't have to) and write the answer yourself on how you made it work for your case. – A.B Dec 29 '18 at 2:33
