    The tip (TD) should connect to DB9 pin 2 (RD)
    The ring (RD) should connect to DB9 pin 3 (TD)
    and the sleeve (GND) should connected to pin 5 (GND)

    Could the tip and the sleeve be reversed? However, if they were reversed, it would seem odd that we would see the data shown in the log. See the diagram that OLdDog posts: http://www.tivocommunity.com/tivo-vb/showthread.php?p=2484034&&#post2484034

    Sorry, had numbers reversed.

    Tip - 2

    Ring - 3

    Ground - 5

    Something I just noticed was that the "Guest" account was not enabled in the User Accounts section of the control panel. I'm going to try again in a few minutes and post the results.

    I'll get this damn thing yet!! :)

    OK, this might be a valuable step for everyone with XP. You have to go to the control panel and User Accounts and turn on the "Guest" account. I did that and it worked perfectly!!!

    Thanks everyone for the help and guidance and hopefully I've helped a few with my findings.

    Take Care,

    Eric

    Congratulations, Eric. Yes, enabling the Guest account is very important. This is usually done when setting up the Incoming Connection and can be done after the fact in the Control Panel. Thanks for telling us about your success. I'm sure it will help someone else set up their serial/PPP!

    Happy TiVoing.

    That screen is giving the "Guest" account permission but the actual account needs to be enabled (at least it did in my 2 computers) in the User Accounts section in the control panel. I gave the guest account permission as shown in the screen above during all of my set up attempts but that didn't enable the actual guest account.

    Take a look in the control panel and click on the "User Accounts" icon and you'll see what I'm talking about.

    Thanks for all the help.

    Hi Eric,

    That is an interesting note. Out of curiosity I checked my User Accounts in the Control Panel on my notebook used for making serial/PPP connections and the Guest Account is not on! However, in the Properties for Incoming Connections, Guests is check marked. And I then forced a Daily Call and everything went OK.

    I'm glad you found that because I know it will give others a place to look when they have challenges like yours. It is interesting, too, that all Windows XP setups are not created equal. :) That is why it is really tough to find a one-size fits all approach to answers here.

    And if I see this line in a person's modem log, I will suggest the turn on Guest Account in the Control Panel for a test: 07-30-2005 13:07:05.026 - Recv: <ff>}#<c0>!}!

    Thanks again!

    John

    Thank You John for helping me troubleshoot this. I guess we can add "Make sure your Guest Account is turned on in the Control Panel" to the list of things to check when people are having trouble.

    Take Care,

    Eric

    Hi bigco9,

    Obviously you found the mdmhayes.inf file and made the specified changes to it? You deleted the mdmhayes.pnf file? Did it go to a Recycle Bin? If you are using an active Recycle Bin, you may want to empty it before you re-boot the computer.

    See previous posts in this thread where the Recycle Bin gave a problem like yours. http://www.tivocommunity.com/tivo-vb/showthread.php?p=3078911&&#post3078911

    Keep us posted.

    Yes I finally found the file, made the changes to it but I still can't get it to know that the ~ = the ring command. Does any one have a copy of a working inf file that I could get? I cleared the recycle bin out rebooted but no luck, I even tired to use the install command on the inf file it recreates the pnf file and that didn't even work... I'm running out of ideas here....

    This might give you a hint because jptivo's symptoms were very similar to yours. He also suggests after you delete the mdmhayes.pnf file, delete the modem and the Incoming connection you had created earlier and recreate them after the reboot.

    http://www.tivocommunity.com/tivo-vb/showthread.php?p=2940244&&#post2940244

    Here were the instructions for setting up serial/PPP that I used:

    http://www.tivohelp.com/archive/tivohelp.swiki.net/45.html

    Static IP addresses work better than the DHCP addresses suggested in the above instructions.

    I have attached a copy of my mdmhayes.inf file. If you want to use it, rename it to mdmhayes.inf.

    Keep us posted.

    What is the IP address that is assigned to your computer? You can find this with a Command Prompt and typing ipconfig. You need to assign specific IP addresses the will be handled by your router.

    You are making progress. The ~ is now recognized.

    For those of you with Direct TV DVR-40's and windows XP home, I found something very important that has to be checked inorder for PPP over serial to work and here it is:

    In your incomming commections properties box under the Virtual Private Network section you MUST check Allow others to make private connections to my computer by tunneling though the internet or other network

    I did this and My Direct Tv DVR made it's very first successful PPP over serial call at 115,200 kbs....

    My Thanks to all those who helped me with this issue!

    And I hope this information will help some one else.

    Heres a copy of my modem log:

    First of all, a pat on the back to everyone here. I have read every post in this 14-page thread and am thoroughly amazed by how helpful and thoughtful the community is here.

    Indeed, this post got me very far along in the process...... though not quite all the way :)

    How my situation differs from what I've found here -- I get on the internet through the wireless connection in my building.

    Using the post, I've gotten all the way up to the point where I have the Tivo dial out. I get the successful HyperTerminal garble, the modem finally gets past connecting and the vile NEGOTIATING, and on one wonderful time, the Test call actually went through. Since then, however, no test call, and never a daily call.

    From watching the network status, when the Tivo goes into "Configuring" mode, a whole bunch of data (well that's relative, I was used to seeing 571 bytes for days! Now I get 20k) comes down, but then the data counter stops abruptly. Its as if it will get data for a few seconds, but then it just can't/won't anymore.

    Any ideas? I've tried 115k, 19.2k, and 9.6k with the same situation :(

    Do you have a router? What is the IP address given to your computer? Are you assigning two static IP addresses?

    Keep us posted.

    Hi John,

    Yes and no to the first question: my building has a wireless router (to which I do not have access) that distributes wireless internet to the building's residents. I have been able to ascertain it is distributing Verizon HDSL.

    The router assigns an IP address in the range 192.168.1.xxx and I used the same subnet with two static IPs (192.168.1.100-101) and also tried it with DHCP. With the static IPs, it has made a successful test call twice now, but not with any kind of regularity (i.e. it often fails while configuring) and never a daily call.
