    Modem ppp/pppd Issues


    Can anyone familiar with pppd (ppp) shed some light onto why my modem dissconnects a second after establishing a connection? The output is as follows:
    Code:
    [root@localhost ~]# pppd call ac775 
    Serial connection established. 
    using channel 2 
    Using interface ppp0 
    Connect&#58; ppp0 <--> /dev/modem

    LCP terminated by peer &#40;Normal Termination by NCP&#41; 
    sent &#91;LCP TermAck id=0x0&#93; 
    Modem hangup 
    Connection terminated.
    I may also want to note that this is a GPRS modem (cellular wireless)

    Thanks.

    You'll have to send me a link, I'm not sure what you're reffering to.

    One of the rules of the forum requests that we not double post or cross post by posting the same material on two different forums. While it requires the poster to choose between two forums that may seem equally suited to the post, it reduces confusion and aggravation a bit both for those seeking answers and for those trying to help. It's okay to post in one forum to send traffic to the forum where the "real" post is, though. You could edit your first post here to accomplish that, otherwise the mods might remove this thread.

    As to your ppp question, I'm working to resolve a smilar problem and will let you know of any progress, at your other post.

    I solved the problem, I needed to edit one of the modem chat scripts to include a missing apn. I deleted the duplicate posts
