USB Hardmodem Failing to Authenticate to ISP
 
I recently bought a RNX-56USB modem. It's a hardware, conexant based USB modem from Rosewill. It had many reviews (from NewEgg) that talked about it working with Linux. I'm running Fedora 11, 64 bit version.

Anyway, I plugged it in before booting, and made the following config file:
Quote:

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Phone = xxx-xxxx
ISDN = 0
Username = xxxxxxx
Init1 = ATZ
Password = xxxxxxx
Modem = /dev/ttyACM0
Baud = 460800
Stupid Mode = 1
I have already verified the validity of my phone number, username, and password more than once.

When I try to connect with wvdial, this is what I get:
Quote:

--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
OK
--> Modem initialized.
--> Sending: ATDT383-0500
--> Waiting for carrier.
ATDT383-0500
CONNECT 9600
--> Carrier detected. Starting PPP immediately.

--> Pid of pppd: 3578
--> Using interface ppp0
--> Disconnecting at Wed Jul 22 18:23:04 2009
--> The PPP daemon has died: A modem hung up the phone (exit code = 16)
--> man pppd explains pppd error codes in more detail.
--> Try again and look into /var/log/messages and the wvdial and pppd man pages for more information.
It also dumped this into the /var/log/messages file:
Quote:

Jul 22 18:23:03 sovsys500 pppd[3578]: Connection terminated.
Jul 22 18:23:03 sovsys500 pppd[3578]: Exit.
Just to make sure 'stupid mode' wasn't messing it up, I commented it out, and tried again. This is what I got:
Quote:

And it put the same stuff as before in my /var/log/messages file.

What's the next step from here?

Thanks for any help you can give,

Hi,

Take a look at 'What options should I use? (No PAP/CHAP)'.
