AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 1-25 are cancelled.
New claims 26-36 are added and determined to be patentable.
[ 26. A method comprising:
receiving at a key code generator device a signal that indicates to the key code generator device that a test command was successfully received by an electronic consumer device;
using the signal by the key code generator device to cause a key code set to be selected from amongst a plurality of key code sets;
receiving by the key code generator device a keystroke indicator signal from a remote control device, wherein the keystroke indicator signal indicates a key on the remote control device that a user has selected;
generating by the key code generator device a key code using the keystroke indictor signal and the key code set;
modulating by the key code generator device the key code onto a carrier signal, thereby generating a key code signal; and
transmitting by the key code generator device the key code signal to the electronic consumer device.]
[ 27. The method of claim 26, wherein the key code generator device transmits the test command to the electronic consumer device.]
[ 28. The method of claim 26, wherein the test command comprises a command to power on the electronic consumer device.]
[ 29. The method of claim 26, wherein the signal that indicates to the key code generator device that the test command was successfully received by the electronic consumer device comprises an electromagnetic noise signal introduced into an electrical power wiring through which both the electronic consumer device and the key code generator device receive power.]
[ 30. The method of claim 26, wherein the test command comprises a last transmitted one of a plurality of test commands.]
[ 31. The method of claim 26, further comprising receiving by the key code generator device a data that specifies a type and brand for the consumer electronic device and using by the key code generator device the data to cause the plurality of key code sets to be identified from with a key code set library.]
[ 32. The method of claim 31, further comprising causing the key code generator device to display on a television display a menu navigable through use of the remote control device for use in obtaining the data.]
[ 33. The method of claim 26, wherein the key code consists of a binary number.]
[ 34. The method of claim 26, wherein the key code comprises a binary number and timing information and the timing information defines how the binary number is modulated onto the carrier signal.]
[ 35. The method of claim 26, wherein the keystroke indicator signal comprises a command code and a device type identifier.]
[ 36. The method of claim 26, wherein the key code signal comprises an infrared signal.]
