Sierra Wireless MC7710 Ports | |
It depends on enumeration scheme. For DIP mode with (default) USB composition #3 selected, /dev/ttyUSBn ports are expected to be mapped as follows: | |
n=0 - HIP (CnS); | |
n=1 - QCDM (diag); | |
n=2 - NMEA; | |
n=3 - AT command; | |
n=4 - modem. | |
Please note that there isn't necessarily a 1-1 relationship between the MCxxxx serial interface numbers and the Linux /dev/ttyUSBn devices. The latter number space is shared between all USB serial devices in the system, and there is no guarantee that the AT port always will be /dev/ttyUSB2 (or whatever). |
