Looks like its already defined in the kernel!

It sees it.

More importantly, the driver sees it and has used cuaU0.*

This is where you need to do a bit of experimenting.  Some modems
register these "sub ports" and others do not.  Some are for out of band
control and one will be the device you actually use in your ppp config.
 The init string sort of depends on your carrier. But a basic one to try
in ppp.conf is below.  For the set device line, you might need to change
it to /dev/cuaU0.1 or /dev/cuaU0.2

invoke with ppp -ddial u3g

You might need the authname and auth key, you might not. For the context
you might need to change it from internet.com to something else.  Again,
ask your carrier for that info. Try first without the CGDCONT line as
the default in the modem might do the trick.


u3g:
 set device /dev/cuaU0.0
 set server /var/run/gprs-internet "" 0177
 set speed 921600
 set timeout 0
 set authname wapuser1
 set authkey wap
 set dial "ABORT BUSY TIMEOUT 2 \
        \"\" \
        AT OK-AT-OK \
        AT+CFUN=1 OK-AT-OK \
        AT+CMEE=2 OK-AT-OK \
        AT+CSQ OK \
        AT+CGDCONT=1,\\\"IP\\\",\\\"internet.com\\\" OK \
        AT&v OK \
        ATD*99# CONNECT"
