Series 1 Serial Port Connection?

[JackRazz]

Hey everyone,
I just put in a new drive in my Phillips Tivo Series 1 using InstantCake's software. A couple of years ago, my modem got fried by lightning and I use the serial port to download the daily updates.

I also want to connect to the Tivo with a terminal program. If I set up something like

echo '/bin/bash --login < /dev/ttyS3 >& /dev/ttyS3 &' >> rc.sysinit

in rc.sysinit or rc.sysinit.author, will this cause a conflict in using the serial port for daily updates?

Thanks - JackRazz

Update:

It works. I went ahead and mounted the drive to my pc and added the following to the to the end of the rc.sysinit file and it works.
/bin/bash --login < /dev/ttyS3 >& /dev/ttyS3 &
I'm having one significant problem. I had to delete the Incoming Connection in the Windows Network Panel to make it work. So now my Tivo can't call for it's schedule updates. It's a shame that the Incoming Connection doesn't have a disable property! Anyone have any ideas for a solution for this?

Also, I just want to make sure I understand. Did I need to modify the rc.sysinit file for a serial terminal connection for Tivo software version 3.0.01?
