| # Sierra Wireless HL7618 modems come from the factory configured for | |
| # CDC-ACM/NCM mode. This mode can be used to establish an internet | |
| # connection using PPP for CDC-ACM, or NCM. It can also be used | |
| # in MBIM mode. The modes can be changed by issuing 'AT+KUSBCOMP=<MODE>', | |
| # where <MODE> is 0 for ACM/NCM, or 2 for MBIM. | |
| # | |
| # When in NCM mode (+KSUBCOMP: 0), the modem appears to Linux as having 7 | |
| # distinct interfaces: | |
| # 1. tty 0 - AT command interface/ACM interface | |
| # 2. tty 1 - Proprietary debug interface | |
| # 3. tty 2 - AT command interface/ACM interface | |
| # 4. wwan 0 - NCM interface | |
