-// 5.2.34 - <A address aspect> Command fopr DCC Extended Accessories.
-This command sends an extended accessory packet to the track, Normally used to set
-a signal aspect. Aspect numbers are undefined as sdtandards except for 0 which is
-always considered a stop.
-
-//        - Exrail ASPECT(address,aspect) for above.
-     The ASPECT command sents an aspect to a DCC accessory using the same logic as 
-     <A aspect address>.
-     
-//        - EXRAIL DCCX_SIGNAL(Address,redAspect,amberAspect,greenAspect)
-      This defines a signal (with id same as dcc address) that can be operated
-      by the RED/AMBER/GREEN commands.   In each case the command uses the signal
-      address to refer to the signal and the aspect chosen depends on the use of the RED
-      AMBER or GREEN command sent. Other aspects may be sent but will require the
-      direct use of the ASPECT command.
-      The IFRED/IFAMBER/IFGREEN  and ONRED/ONAMBER/ONGREEN commands contunue to operate
-      as for any other signal type. It is important to be aware that use of the ASPECT
-      or <A> commands will correctly set the IF flags and call the ON handlers if ASPECT
-      is used to set one of the three aspects defined in the DCCX_SIGNAL command. 
-      Direct use of other aspects does not affect the signal flags.
-      ASPECT and <A> can be used withput defining any signal if tyhe flag management or
-      ON event handlers are not required.

-    This cutout will only work on a Mega2560 with a single EX8874 motor shield
-    configured in the normal way with the main track brake pin on pin 9.
-    <C RAILCOM ON>    Turns on the cutout mechanism.
-    <C RAILCOM OFF>   Tirns off the cutout. (This is the default)
-    <C RAILCOM DEBUG> ONLY to be used by developers used for waveform diagnostics.
-       (In DEBUG mode the main track idle packets are replaced with reset packets, This
-       makes it far easier to see the preambles and cutouts on a logic analyser or scope.)

-         JMRI_SENSOR(100)   is equenvelant to <S 100 100 1>
