PPP Networking using a Raspberry Pi

[dzs50]

I was wondering if anyone has used a Raspberry Pi to provide the network interface for the tivo's serial ppp internet connection?
They are now more available on the second hand market.
I currently have to connect up my xp laptop every time I want to run the daily update.

Blackberry, Ice Cream Sandwich, Jelly Bean, and now Rasberry Pi... Is there something going on...

but what would provide the serial interface for the Pi? You could use a USB serial device, but at that point you might start needing powered hubs (the Pi doesn't provide much in the way of current on its USB ports, because it only runs off USB voltage/current itself)

Probably just easier (and far less cables too) to get a Cache or Turbo card and upgrade your TiVo.

Thanks, that is a good point. I will check the power requirements of my adapter.

If anyone knows of a spare network card for sale, then please send a me a PM.

It has one already. Not sure if you need anything more than the right cable - many of the posts on the RPi forums seem to mention breakout boards of varying descriptions - but there is a serial connection provided by the UART.

That hadn't occurred to me, but you do need some components. The UART available via the GPIO connection runs at 3.3V, so you need some circuitry to match to 5V RS232 signalling.

I use a serial connection to my Pi ( thought not to a tivo ) .. I bought one of these

works a treat

If the Pi won't work, you could consider a Pogoplug -- that is what I use. Takes more space and power, and less interesting, but it works.

Thank you all for your posts and links . They certainly give me food for thought.
