I have just installed Linux Redhat 4.2 about 2 weeks ago. I would like
to go completely to this as an OS, but cannot, since I can't get the
modem to stay connected.
I have included a (relevant) clipping from syslog (/var/log/messages),
with kdebug set at 21, for pppd, below. As you can see I am sending LCP
requests, and apparently not receiving anything back (or at least
nothing 8N1). I spoke with my ISP, and all there modems are set to
8N1. I have read all DOC I can find on this, and have troubleshot this
to the best of my ability. I have recompiled to the newest stable
kernel. I have tried every command line option that I have ever read
about that seems, even remotely, relevant. I have even compiled a
kernel with a SLIP slip setting for 6-bit encapsulation, although I
doubt that that would be related to this problem. All efforts have been
bitter failures.
I have 3 suspicions:
1. The problem is caused because I have a p-n-p modem (although, I use
the BIOS setup utility to
turn off p-n-p for my PC). I saw a reference in here once about
"isapnptools". Where would I
go about finding these tools?
2. Perhaps a problem with this version of pppd (2.0.0)? I have not
upgraded to the newest version,
because I have not yet given up on this one.
3. My modem is simply not set at 8N1, when pppd gets control of it.
Are there any AT commands
that I can use to set it?
