I have a hdvr2 dtivo upgraded with instacake 6.2 and ptvupgrade.  I had an dynamic ip address working over my hardwired home network for about a year.  Ignoring the maxim - if it aint broke, don't fix it - I tried to set up a static ip address.  I must have gotten it part right because it shows up on angryip with the ip address that I gave it. However, I have lost my ability to open a telnet or any other kind of connection.  I think the problem is that I ran a tcl script from dealdatabase (netconfig.tcl) rather than following the instructions from this site.  I also think I misunderstood what the gateway is - I supplied the address for the "gateway" listed in my router (which I think is the my isp's ip address) rather than the ip address for my router as the gateway.  Rethinking the problem, I would like to return my tivo to its prior ptvupgrade network settings (DHCP) and give it a static ip address from within my WRT54G linksys router using the mac address of my usb adaptor following this suggestion.

My understanding is that in order to fix my networking settings, I will need to establish a bash session over a serial cable -- something I never needed before because ptupgrade worked so perfectly.  I built a serial cable (following this diagram) and have connected it to my pc.  However, when I try to connect to the tivo with teraterm (9600,8,N) nothing happens when I hit enter or type -- no prompt, no echo.  I am confident that I have the right serial port (I tried them all anyway just to be certain).  I'm thinking that I may be missing something simple as I have no idea how to get the bash prompt or what I should see after I connect with teraterm or what to do next.  Can someone point me to a thread that explains how to get a bash prompt over a serial cable.  I really need something that continues where this post leaves off.  I found this explanation of how to obtain output from the serial console.  Can I assume that the follow commands (or their equivalent) were set up as part of the instacake/ptvupgrade:

***  Make sure your boot parameters (bootpage -p /dev/hdX)  include dsscon=true console=2,9600 

export TERM=xterm
export PS1='\h:\w$ '

#Setup HOSTNAME
hostname HDVR2

#Start BASH
/bin/bash/dev/ttyS2&

 Am I correct in believing that if the cable works correctly and the tivo has been configured correctly, a bash prompt should appear after I establish a connection with teraterm without entering any other commands?

Given that my system was upgraded with instacake and ptvupgrade images and that I don't get a bash prompt, should I assume that my cable is built incorrectly (BTW i've ordered a serial cable from 9thtee in case I built the cable wrong but won't get that in the mail for a few days)?

 Any help for this bone head would be appreciated.
