[PATCH v2] plugins: telit: send AT&C0 on both channels

[=?unknown-8bit?q?Andr=C3=A9?= Draszik <git@andred.net>]

[-- Attachment #1: Type: text/plain, Size: 962 bytes --]

At least firmware version 12.00.405 on the UE910-EUR otherwise
closes the AT command port whenever the PPP connection is
dropped, and we'd be left in a funny state.
