Here is my problem:
I have a US Robotics Sporster 33.6 External Serial Modem And I'm trying to run it on Fedora Core 4. After reading the HowTo-Modem serveral times I'm stumped.

Using Fedora Core's Network Configuration (in gnome) it cannot find the modem (even when I manual enter it's location and settings), to be a bit more specific it says Initalizing Modem... and hangs indefinitely.

kppp can find the modem... but I have yet to successfully dial with it... not sure what the problem is there. it always hangs and gives a sequence error.

Ussing wvdial, I can get it to dial, but I cannot get it to negotiate the connection. (Never authenticates)

I have taken a lot of steps... about 4 hrs worth... to fix this... and I'll wager (am hoping) it is something simple.

Here is what I'd like to do:
I'd like to get the Network Configuration tool to work... however I would be content to use kppp or even wvdial
if that was the only way I could connect.

Here is the wvdial.conf file I have... (minus ISP phone, user and pass of course)
CODE
    [Dialer Defaults]
    Modem = /dev/ttyS0
    Baud = 115200
    Init1 = ATZ
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    ISDN = 0
    Modem Type = Analog Modem
    Phone = <ISP Phone Here>
    Username = <User Name here>
    Password = <Password here>

This will get the modem to dial, and handshake with the ISP, but then I get the following
(and because I'm sure someone will not notice, I did remove the phone from the log and replaced
it with <ISP Phone Here>... it is not actually trying to dial a string sequence):
CODE
 
    [root@WhamBall ~]# wvdial
    --> WvDial: Internet dialer version 1.54.0
    --> Initializing modem.
    --> Sending: ATZ
    ATZ
    OK
    --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    OK
    --> Modem initialized.
    --> Sending: ATDT<ISP Phone Here>
    --> Waiting for carrier.
    ATDT<ISP Phone Here>
    CONNECT 26400/ARQ
    --> Carrier detected.  Waiting for prompt.
    --> Don't know what to do!  Starting pppd and hoping for the best.
    --> Starting pppd at Thu Nov 10 17:45:09 2005
    --> pid of pppd: 2483
    --> Using interface ppp0
    --> Disconnecting at Thu Nov 10 17:45:31 2005
    --> 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.
    --> Auto Reconnect will be attempted in 5 seconds

I looked up the code in the man pppd pages... and the code was rather ambiguous... "The link was terminated by the modem hanging up".

I have tried various settings for the DIP switches on the back, I have tried to turn Carry detect to go with
connection and to force Carry Detect on...

Incase anyone is wondering here are the DIP Switch Positions I presently have (I have tried many many combinations up to now..)
{Indicates selected switch possition}
Switch 1 Data terminal Ready {Normal} - Override
Switch 2 Result Codes type {Numeric} - Verbal
Switch 3 Result Codes {Suprress} - Display
Switch 4 Echo offline commands {No Echo offline commands} - Echo Offline commands
Switch 5 Auto Answer {off} - on
Switch 6 Carry Detect {Override} - Normal
Switch 7 Defaults {Factory Defaults} - NVRam Defaults
Switch 8 Mode {Smart} - Dumb


Here is the info on the box (at least the parts I think are important):
CPU: 1.0 Ghz AMD
Ram: 384 MB
Serial Ports: 1 (on motherboard)


The following were requested in the first post in hardware (recomended info)

Any help would be apreciated...

Guess it just wasn't ment to be... it is older technology... amazing how fast it passes people by.

Well thanks for the views, I see there were a lot of them... I haven't figured it out either.

Please allow for more time for someone to reply and post any possible helpful information..

Has it been long enough?

I still have the modem... still have linux... but I still don't have the modem working. I have changed distros probably 4 or 5 times now. Well in any case I don't guess anyone really wants to take a poke at an old dial up modem (external serial port...).

Thanks for the reads.
