Advertisements My setup: An unmodified TiVo Series routing through a Windows XP Pro box routing through a Linksys 4-port Cable/DSL Router (BEFSR41) running firmware 1.42.6. XP gets it's IP address via DHCP from the router. I followed Geffler's and Otto's instructions with these exceptions: I used the TiVo Null Modem cable sold by 9th Tee <http://9thtee.com/tivoupgrades.htm>. No gender changers or null modem adapters are needed as the cable the right connectors -- a 1/8 inch stero plug for my TiVo and a D9 jack for my XP box's serial port. TIVONMCABLE TiVo Null Modem Serial Cable - 10' Long $7.95 TIVONMCABLE20 TiVo Null Modem Serial Cable - 20' Long $9.95 Like Spire I had to allow VPN connections, but I didn't have to turn on SPI Didn't have to open any ports. I did several test calls and every other succeeded/failed. I'd just had a modem call before adding the PPP connection so haven't been through a regular call yet.
