AT Commands on iMac OS 10.6.1

I have an ISDN internet connection using a USB netMod Modem from Intracom. The only internet option available where I live. My connection with the Mac only sees one channel, but with my PC the connection uses both channels. The netMod people sent me the following letter......
"I'm sorry to inform you that the netmod is compatible to Mac OS versions until version Mac OS X 10.4 There is no support for further Mac Os .
Nevertheless you have managed to have the connection , I can only help you by telling you that the only way to use both channels for internet (MLPPP) is by using the AT commands
1) AT B0
2) AT KAS0
Or enable the Multilink PPP (MLPPP) from the extra settings
But I cant inform you where is the configurations to add those commands or the extra settings at a Mac 10.6.1 OS "..........
How does one use AT commands on Mac OS 10.6.1 or how does one enable the MLPPP.
Any info will be appreciated. Thanks.

The AT commands can either be sent by a stand alone program to set the modem up before use (see the next paragraph) or via the software that comes with the modem. It appears that the software is no longer supported and you are left with the stand alone set up.
Have a look at this web page http://homepage.mac.com/dalverson/zterm/ , its a terminal emulation that is designed for communicating with serial ports or modems on USB ports. If you can get this working you will be able to communicate with the modem using the AT commands.
Note:- You can alter many items with the AT command, some survive a reboot of the modem and could stop the modem working. Use the AT commands at your own risk.
Its possible that someone on these forums has an easier way to do this for you, lets hope so.
regards

  • Deleted .DS_Store files, Now my drive is EMPTY! Help!

    In Mac's Terminal application I used a command I found on Adobe's website to delete .DS_Store files because I thought I had some corrupt ones. The command was to delete all of them on the entire machine. Since they are not critical files, I figured what the heck. Well, maybe I typed something wrong. I know Terminal is very touchy (now I know). But all of the files on my external drive are gone. When I double-click the drive icon, the window shows 0 items. Can anyone tell me what went wrong and how to undo the problem. I think all the files are still on the drive, there's just no directory to view them - so it says there's 0 files. Help please!
    Here's the commands I entered in Terminal. Note that the first line is the command that was supposed to erase the .DS_Store files. The second line asked for my password. When I entered it, it may have deleted the files, but then it gave me no new command prompt. So everything you see from the "sudo" on is things I entered trying to get a new prompt. So I think that's where I screwed something up.
    neals-imacs-imac-g5-5:Clients iMac$ sudo find / -name ".DS_Store" -depth -exec rm {} \;

    sudo
    sudo ls

    By the way, the Adobe article that showed how to delete the .DS_Store files (in case that helps) is at: http://kb2.adobe.com/cps/168/tn_16831.html

    I just did the same exact thing (but recovered!). I hope you didn't empty your recycle bin/trash yet! Your library information is there - get it out!
    The instructions on the web are a bit obtuse - what you need to do is delete ONLY the "iTunes Music" folder within the default iTunes location; I deleted the ENTIRE "iTunes" folder and saw exactly what you do now. You need to restore the "iTunes Library.itl" and "iTunes Music Library.xml" files, and you'll be back in business.
    Not sure how you'll recover if you can't get those files back...

  • HELP! My iMac wont respond to install disc or any commands

    I know I'm taking a trip in the "Way back" machine. But I'm pretty resourseful and haven't been able to find my problem. Either I need a Mac super genius or it’s something stupid simple that I’m overlooking.
    Specs:
    iMac G4 Serial# XXXXXXXX Sep. 2003 – July 2004
    1.25GHZ/ 256MB/ 80GB 17” Screen
    PowerPC 7445
    History: I bought this used with the computer’s monitor backlight out. I could still barely see the sign-in page when I looked at a certain angle, so that was an indicator to me that the OS was working. So I replaced the monitor. At the same time because of owner exchange I had to replace the hard drive with a fully wiped blank one (Deskstar ATA/IDE). I purchased an install disc set 10.4.8, which according to Apple this computer is compatible with 10.2.3 thru10.5.8.
    Problem: After reassembly, the replacement monitor works fine. But the system won’t respond to anything. All I get is the gray screen with the apple smiley face folder that alternates with a question mark. It won’t respond to the install disc, or any commands for that matter. Of course I double, triple, and quadruple checked my connections from reassmebling. Here’s what I’ve attempted, all ending up with the same screen display.
    During power-up
    C (…of     course to boot from the install disc. It just ejects the disc after about     30 seconds)
    CMD-OPT-SHIFT-DEL
    D (wont     respond to hardware test)
    CMD-S     (won’t go into single user mode. It just goes to the same gray screen)
    OPT (this     is the only way I get a different screen. It shows the recycle page symbol     and continue symbol. It will recycle the OPT process to stay on this     screen, but it won’t continue if I press that selection – nothing happens
    I’ve reset the PRAM
    I’ve tried different keyboards (all Apple)
    I’ve tried plugging the keyboard into different USB slots
    I’ve replaced the Hard Drive with yet another just in case. I’ve tried alternate jumper settings on the hard drive. The original wasset to “Cable”, so I set it to that. But I also tried “Master” jumper settings– no change in results. I can’t say for certain that I hear the DVD/CD drive spin up. But I figure even if I had a bad install disc or bad optical drive, I should still be able to get to the black screen single user mode, yes?  So I’m at my wits end. Can any of you Mac geniuses out there please help me? Thanks
    <edited by Host>

    Install discs are specific to the machine they came with.  You cannot use them on any other machine, so the ones you bought are useless.  Buy a retail black faced copy of either Tiger or Leopard and you should be able to boot your machine, you need to format the drive as Mac OS extended (Journaled) when you first boot from the new retail disc.
    I have also asked that your serial number be removed, it's not a good idea to post it.

  • HT3910 Hi, I'm trying to create a new account because I have bought an iMac second hand and the previous user doesn't remember his admin account password. Would someone advise me on what command prompts I need to write in order to create a new account. Th

    Hi,
    Just wondering how I can create a new account and password?
    I've bought a second hand iMac from a dealer who hasn't fully erased the previous owner's user name and password. Therefore , I can't update or install any new password or update to Mountain Lion...
    There is also no installation disc, so I don't seem to be able to reset the password that way.
    I've just gone into the dos text :/root and wondered what I can do to create a new account and password without having to reinstall Snow Leopard?
    Any help would be greatly appreciated.
    Thanks.
    Steve

    Follow the steps in this article. Be sure to enter the commands exactly as written, paying attention to case and spaces, or lack thereof.

    What system are you running?  Have you tried going to the Canon website to download and install the latest drivers for that model?
    Are you running Time Machine?

  • Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up.

    Holding down the option key when booting my iMac lo longer shows me my bootable external drives, the system just boots up to the main system. Also, holding down command, option,P,R no longer zaps the p-ram. the system just boots up normally. Why do these key fonctions no longer work?

    It could be your timing if on a bluetooth keyboard.  I find it best to hit the keys as soon as i hear the chime, release and hit them again but this time holding them before the chime ends....like a fake pump in football.
    But....you can always open up system preferences, startup disk, and select your bootable clone for booting.  If it doesn't show up there, the Mac doesn't think it's bootable.

  • 22" iMac desktop OSX 10.6.6 Snow Leopard and it won't boot. I've tried shift start, option command+P+R. It's stuck at the restart, all I see is the spinning wheel below the apple logo.

    I have a 22" iMac desktop running OSX 10.6  Snow Leopard and it won't boot. I've tried shift start, option command P R. It's stuck at the restart, all I see is the spinning wheel below the apple logo. And I lost my OSX DVD is there any way to fix this? I just did a software update yesterday and have about 20GB left on my Hard drive. The last thing I did was try to install some plugin's for Pro Tools 8, but it wouldnt let me install so I restarted and now I'm screwed. Please Help!
    other specs for my computer: 3.06GHz Intel core 2 duo processor 500 GB Serial ATA hard drive, iSight, magic mouse, wireless mac keyboard
    iPod classic 160GB (Late 2009), Mac OS X (10.6.6)

    You have to consider the possibility the hard drive may be dying.    If your data isn't backed up, try one of the tools below:

    Once you are sure your data is backed up, we can examine other possibilities.  In the meantime call AppleCare for your original installation DVDs.  You may need them.

    Your HD may be crashed, so you probably should use the oringinal install discs to run Apple Hardware Test in extended mode. If error codes appear this confirms a hardware failure. In addition you cannnot repair the HD using Disk Utility from the startup disk, you have to use the origninal Install discs that shipped with the computer or the most up-to-date version of OS X on a disc that you have.

  • I have rebooted my computer over 20X and performed the soft reset and the option command p.r. my iMac still gives me the gray screen with the file and question mark.

    I have been having issues with starting up my computer for the last 5 weeks it started with a loud clicking sound when starting up and it use to only take turning the computer off and on a few times to get it running. This week it has taken almost a day of me turning off the computer and turning it back on. Last night I did the soft reset and it did come on. I did not shut down the computer and when I returned to it this evening I had to force it to shut down because it was stuck.I have did the soft reset and sad to say it did not work.I decided to try the option command and pr to reset it it did not work do any one have any other suggestions?

    You can get a decent new hard drive for $100, plus labor to install it if you're not comfortable doing it on your own. In contrast, a new computer will cost quite a bit more than that. Of course, if that iMac is very old at this point - like, say 6 or 7 years old - the new drive may be worth more than the computer, and you could use this as an excuse to buy a new one!
