2006.1 Universal Install
G3 iMAC Summer 2001 600Mhz "snow"
logged in as root

Problem: Modem appears not to be detected.
Pon and pppd call provider start the desired chat scripts but system halts after the ATZ call to modem.
System then times out and returns to root prompt.
Chat script etc. are modifications of the default scripts.

As per PPC FAQ recompiled kernel with kernel options, character ????, serial drivers, ESCC support
Still no change in behavior.
? Is there some configuration under which this internal modem should work?

Thanks

I can't remember if those have an internal USB modem or not. Try including the zilog driver as specified in the FAQ and then check your dmesg to see if any devices are found. If there is a serial modem, it will show up here. If not, then you've got a USB modem (most newer machines). The USB modem was introduced right around when that machine would have been made, so I can't say for sure, sorry.

Jose, thanks for pointing me in this direction concerning modem types.

The Apple website has this for the summer 2001 snow:

• built-in 10/100BASE-T Ethernet for easy DSL and cable modem access, and a 56K V.90 modem;

On the Apple site http://docs.info.apple.com/article.html?artnum=50055 has *.pdf's for AT Commands for the Apple Internal USB Modem and AT Commands for internal modems. The first was copyrighted in 2001 and the second was copyrighted in1998.

So it appears that the snow might have a usb modem which gives me some more work to do to figure this out. Too bad I blew the OS 9 away or I could check the system profiler for more info. Uff-Dah, Mike Miller

If it's got a USB modem, you're out of luck. I would try the zilog driver as mentioned in the FAQ and see if it finds the modem, like I said above.

Jose, At the Apple site

http://developer.apple.com/documentation/Hardware/hardware2.html

for the October 2001 model (thanks to the Serial Number decode site in Europe) says:

"...The iMac comes with a built-in fax modem. snip the following features:
* modem bit rates up to 56 Kbps (supports V.90 and K56flex modem standards)
* Group 3 fax modem bit rates up to 14.4 Kbps
The modem appears to the system as a serial port that responds to the typical AT commands. snip"

The phrase "appears to the system as a serial" is a little unclear but given the options you mentioned, I will run with this one.

I think I have recompiled the kernel with the pmac_zilog or the closest thing I could find pmaczilog with ESCC support, i2c and ppp but I will look at that again to see if I miss anything. The apple modem manual suggest AT&F for starters and I had ATZ so I will try AT&F ATDTnumber. My goal in this project was to learn and it has delivered that in spades. Mike

less /var/log/dmesg

pmac_zilog: i2c-modem detected, id: 1

So methinks it now is just a matter of the correct scripts and commands for pppd and pon etc.

Thanks, Jose, for all the help. Mike Miller

I am still fighting (and learning about) the set up of PPP in Gentoo on an iMac Snow.

Status: modem does not respond to an AT command issued from minicom but;
when an OS X harddrive is installed, it dials out and connects without trouble.

/etc/ppp/options, /etc/ppp/chat-provider and /etc/ppp/peers/provider has all been setup along with conf.d/net and the pap file. I even stole the initialization string from OSX but..

When pon is issued, the process stops with the ATDTnumber command, times out and returns to root.

So one has to conclude the modem is not responding to pon and is not replying with OK

I notice there is some differences amoung the various PPP How To's esp. with respect to the /etc/resolv.conf and /etc/conf.d/net but I have placed the nameservers numbers in conf.d as per the Gentoo How To

However, I do not seem to even be getting far enough along in the process for that to be an issue.

Has anyone setup pppd on an iMac with the internal 56K fax/modem? If so how? Thanks
