' By observing the signal from a remote control with an oscilloscope, the following
' parameters were recorded. To adapt this program to another remote control model, change
' the values below:
CarrierFreq$ = "32768" ' Type in the infrared carrier freq here.
' this value is in Hz
OnTime$ = "30" ' Type in the burst on time here.
' this value is in mS
OffTime$ = "10" ' Type in the burst off time here.
' this value is in mS
' These variables hold the number of pulses that form each command:
PowerToggle = 20 ' Turn the TV on and off (twenty pulses)
ChannelUp = 9 ' Go to next channel
ChannelDown = 12 ' Go to previous channel
VolumeUp = 3 ' Increase volume one notch
VolumeDown = 5 ' Decrease volume one notch

' This array is used as a data table which, given a command menu number as an index,
' returns the number of pulses in a given infrared pulse stream.
