nk7110.c version ???:
Config 1: Linux, serial connection
Note: you don't need to specify the exact model number because
model = 7110 works with all models supported by this driver (the driver will automatically recognise the phone).
Note 2: this driver also supports the FBUS protocol over an MBUS serial cable using
connection = m2bus but not all phones support this mix and it is so slow that you will want to use it only as a last resort.
Reported to work is 6210 with firmware 05.17;
no information about other phones.
