[PATCH 2/2] usb: serial: option: add AT ports for ZTE P685M

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Only 1st (DIAG) port was supported, support ports 1 (PCUI) and 2 (Modem)
on ff/00/00 too. Ports expose AT command interface.

The modem is used inside ZTE MF283+ router and carriers identify it as
such.
Interface mapping is:
0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB
