Allows moving "into" an object so it can be held without going into safe mode (limiting applied current in mA). CH holds position on collision and CL goes limp instead.

	81	+*** #254QID120  -  For example, this command can scan the entire bus at once for servos without conflict.
82	82	*** Servos use a simple formula to delay their response: 200usec + <id> * 120usec, where <id> is their servo ID 0 to 253.
83	83	*** The first parameter (ex. 120) indicates how many milliseconds to delay between IDs and 120usec is a safe number.
84	84	*** Warning: #254QID with no parameter will still conflict to remain backward compatible with the LSS Config software

87	87	*** Ex. Three servos with ID 0, 5, and 10 and want to configure them to be slots 0, 1, and 2 respectively:
88		-**** #254SLOTCOUNT3\r - configures 3 slots on the bus
89		-**** #0SLOT0\r  -  Don't really have to do this one, servos default to slot 0 on power-up
90		-**** #5SLOT1\r  -  Servo ID5 to slot 1
91		-**** #10SLOT2\r  -  Servo ID10 to slot 2
92		-**** #254QD\r  -  Query all servos for position
93		-**** #254QD0QC0\r  -  Query all servos for position and current (milliamps)

94	94	*** Note: You only need to configure slots once on power-up, #254<cmd> will offset all servo replies based on slot# after this is set.
95	95	*** Note: Why not just use servo ID as slot#? Many LSS bus setups are not using sequential IDs so it's more efficient to assign slot# then expect everyone to change their robot's logical servo IDs to be sequential.
