FAQ
The problem of ”unrecognized option ttyACM1” prompt
while dialing up.
This error prompt means that the modem device cannot be

found. And the solution is to:
1)
Open the Terminal tools, view the modem port
whether exists in system or not. In generally, the
modem port is often showed as "ttyACM0".
2)
If it does not exist, that means the name of modem
port has been changed, due to some operations.
For example, the system goes into Hibernate or
Sleep while the modem is dialed up to connected
with the network, then after the system waking up,
the modem port name will be changed.
3)
To solve this problem, you must re-plug your device
on the system.
