Writting to the IR blaster from linux
I would like to write a small shell script that can make us of the Tivo IR blaster/wand thingies to control my TV's power and volume controls, is this possible? What device is the IR port, ttyS1?
I attempted a few simple tests with the tivoapp turned off (I moved it out of the way and rebooted.) First I tried capturing the remote control signals from my tivo remote by simply cat-ting a button press from /dev/ttyS0 to a file. Then I tried cat-ting the captured file to /dev/ttyS1 (and S3 and S0) and could not get it to do anything to my TV.
Any hints on whether this should work? Thanks,
