Netcfg2 with ppp (3G, UMTS) ?

Question

Hey guys,
I'm currently using wvdial and a profile for that to bring up my 3G connection.
/etc/wvdial.conf
[Dialer Defaults]
Modem = /dev/ttyUSB0
Baud = 460800
[Dialer three]
Phone = *99***1#
Username = three.ie
Password = three.ie
Stupid Mode = 1
Dial Command = ATDT
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init4 = AT+CGDCONT=1,"IP","3internet"
Auto DNS = off
Check DNS = off
How do I make use of netcfg2's PPP capabilities? I see it looks in /etc/ppp/peers/ for a config file there... I tried putting in PEER="wvdial" (there's such a file there) but that didn't work at all.
Any suggestions?

To use netcfg's ppp abilities, you can't use vwdial. You use pppd directly, by writing a peers file and a chat script. I've set up using my phone as a bluetooth modem, but I haven't actually tried yet if it works. But anyway, based on my knowledge this could work:
/etc/ppp/peers/three
connect "/usr/sbin/chat -f /etc/ppp/three.chat"
/dev/ttyUSB0
460800
crtscts
defaultroute
usepeerdns
noauth
novj
novjccomp
nobsdcomp
nopcomp
noaccomp
user three.ie
password three.ie
/etc/ppp/three.chat
TIMEOUT 35
ECHO ON
ABORT '\nBUSY\r'
ABORT '\nERROR\r'
ABORT '\nNO ANSWER\r'
ABORT '\nNO CARRIER\r'
ABORT '\nNO DIALTONE\r'
ABORT '\nRINGING\r\n\r\nRINGING\r'
'' \rAT
OK 'AT+CGDCONT=1,"IP","3internet"'
OK ATD*99***1#
CONNECT ""
/etc/network.d/three
CONNECTION="ppp"
PEER="three"
What I *do* know that works is setting up pppoe. It's very similar, the peers file has a few different options in it and there's no chat script, but otherwise same principle.
