I have recently received my new TiVo unit. Had to have it shipped to an IL address for my "move". It's at my moms house and is being sent to me in TX. My question is serial control. I am currently using 2 directv DVR's via serial control with a USB2serial adapter. This is being used with a MSC-400 by universal remote control. I am very pleased with my recent transition to using serial control. It is more responsive to remote commands and more reliable. Can the new THR22-100 be controlled via a serial connection similar to the directv models? I don't want to give up this feature. Any information is appreciated.
