dial up

[Darren Crotchett <backdoc@netdoor.com>]

I'm trying to get dial up working on a new install of 2.7 with the default
kernel.  Eventually, I'm going to set this box up as my firewall/router
for a home lan.  It is a 486 with 20 MB ram and a really old 425 MB HD.

This is an internal modem.  The brand is Thunderlink.  It's a hardware
modem and has worked well in Linux.  It was actaully easier to set up than
a 3com modem that I have.

Where I'm having trouble is getting a response from my modem.  I think
that my modem is being detected and set up properly because I have a line
in dmesg that says:

pccom0 at isa0 port 0x3f8/8 irq 4: ns16450, no fifo

When I go to the interactive mode for ppp and do a show physical, it shows
/dev/cua00 as the active device.  If I try changing it to 01, 02 or 03, it
gives me an error saying that the device isn't configured.  So, I think
that I'm on the right com port.  Oddly though, this is the same hardware
that I run Linux on and it is set up as /dev/ttyS3 in Linux.  The only
explantion for the difference is that maybe isapnp configures it
differently in Linux.

So, if I go to ppp's interactive mode and type term at the ppp prompt, I
get a new line that (I assume) allows me to send commands directly to the
modem.  But, nothing happens when I type.  Nothing is even echoed to the
screen.  It did echo commands to the screen before, but now it doesn't.  I
don't have any idea what I might have changed to cause that. 

I think that if I could know for sure that my modem was accepting
commands, I could configure all of my .conf files by reading the man pages
and all.  

One more thing that I've tried was echoing commands from the command line
directly into the modem.  For example, IIRC I tried ehco > ATDT#######
/dev/cuaXX (where # is the phone number and XX is each port).  That didn't
do anything either.

I don't know if this would help, but there is an error message that
echoes to all of the open consoles, it is as follows:

date time <myhostname> /bsd: tun0: not multicast capable, IPv6 not enabled

I don't know what that means.  

Here is an excerpt from /var/log/ppp.log:

date time <hostname> ppp[20381]: tun0: Phase: PPP started (interactive
mode)
date time <hostname> ppp[20381]: tun0: Command: /dev/tty: show physical
date time <hostname> ppp[20381]: tun0: Command: /dev/tty: term
date time <hostname> ppp[20381]: tun0: Phase: bundle: Establish

date time <hostname> ppp[20381]: tun0: Phase: /dev/cua00 doesn't support
CD
date time <hostname> ppp[20381]: tun0: Phase: carrier -> ready

I want you to know that I didn't run to the mail list for help right
away.  I did do alot of reading of the man pages, FAQs and mail
archives.  Since I just joined the mail list a couple of days ago, I did
see the last of a thread where a guy was having problems with dial
up.  But, I couldn't find the rest of that thread in the mail
archives.  So, I apologize if this question was recently answered.

I would appreciate hearing any comments or suggestions that you have.
