- Reserved, always set to 0.
The 2nd parameter is a "Backup Control Settings" flag. If it is non-zero, then the current settings
will be backed up in EEPROM, and will remain unchanged through a power failure. Backing up
the "Control Settings" will also backup the "Extended Control Settings". If the second param-
eter is not given, then it is assumed to be 0.
The IR control (IR) and the IR jack (IJ), work differently when disabled. Disabling IR control, by
setting the 'IR' bit to zero, keeps the CVS4 from responding to IR codes, however the front panel
sensor remains operational and any codes received can still be queried for by using the "IR ?"
command. Disabling the IR jack, by setting the 'IJ' bit to zero, completely disables the IR jack. IR
commands are no longer be received through the IR jack if the 'IJ' bit has been set to zero.
