    Bestdata Serial 56k modem problems (56SX-92)


    I've posted about the problem a few places before but haven't gotten many replies, so I thought I'd give it another go. I've been having problems, never gotten the modem working before, and the ISP has been used in linux before without incident. I suppose it's also worth noting that this was a fresh 2005.0 gentoo install on a newly build computer.

    I sent this email to Bestdata but hope someone can help me before they can get around to me, if they ever do.


    Email:

    Hey, I've purchased a Serial modem a ways back, 56SX-92 ("rev2").

    Clearly labeled is that it supports linux, but I've been unable to get it into a functioning state.

    I was first using Gentoo, and when I added the modem in kppp it could query it, but the modem commands section was completely empty. I managed to scrounge some values up and got it to dial and make all sorts of fun noises, but would hang on connect.

    It was hanging at login, I opened up the kppp terminal and talked with the modem myself, feeding it the commands, and got to the login stage. I was then able to log in with my username and password, and it appeared to do something like assign me an IP, but no surf.


    So, later... thinking that it was my fault perhaps from some error during installation, I popped in one of my knoppix livecds (based on Debian).

    The knoppix cd could query the modem, as well as had a full section of modem commands listed. Unfortunately, it would hang at "Initializing modem". So, from my experience in gentoo I changed the init string from ATZ to ATZ1. There I got it to dial up and attempt to connect. Only problem is, in the terminal it stated it was starting the pppd, and never advanced, causing a timeout.

    I then popped in a slax livecd (slackware based) to see if it was just an issue with knoppix and gentoo, and got pretty much exactly the same result as knoppix.


    A person has told me there were linux instructions listed on the cd, but searching all of the pdf manuals I could find nothing.

    I would appreciate all the help you could give me, of course, you can reach me by the email listed (*******@*****).

    Thank you.


    (End of email)




    I've been able to get it to the login request from the server, but it seems kppp tries to reset the modem or something and eventually adds "ATZ" after login like:

    Login: ATZ


    It's obvious at that point that it won't continue successfully.


    I would greatly appreciate if someone could help me fix this, for the sake of getting away from windows again, as well as for the wellness of my sanity.

    I have been using that same modem for about half a year now, and I never had any trouble with it. Perhaps it is kppp that is being screwy, I haven't used kppp for a couple years now. Wvdial is the dialer I'm using currently. I will tell you my init string, I think I had to modify that a little to get it working:
    ATQ0 V1 E1 S0=0 &C1 &D2 S10=2 S11=50 M0
    The ATZ is a command to reset the modem, in case you didn't know, and should be sent before the init string.

    Well, I tried that init string, it had an effect at least, which was quieting the modem.

    It still went to "Login:" and later placed the init screen in the login portion, and then it prompted for a password while kppp was trying to restart the connection process.


    How hard is wvdial to use? How hard is it to set up? what about installation?

    Ok, I got wvdial installed and started trying to mess with it, but am having similar problems it seems.

    Skipping some stuff and starting off:
    Modem Initialized
    Sending ATDT(access number here)
    Waiting for carrier.
    ATDT(access number here)
    CONNECT 115200
    Carrier detected. Waiting for prompt.
    Connected, but carrier signal lost! Retrying..
    Sending ATDT(access number here)
    Waiting for carrier.
    UQKT2 blah.blah.blah.blah.net
    Login:
    Login:
    Login:
    Login:ATDT(access number here)
    Password: Caught signal #2! Attempting to exit gracefully...
    Disconnecting (Date/Time)


    The Signal 2 of course was me closing the deal off since it wouldn't accept a password anyways with the ATDT(access number) as the login.


    What should I hit now?

    Did you edit /etc/wvdial.conf and fill in your username and password?

    I really don't know what else to do, I've never had trouble like this from any modem.
