; Change History (most recent first):
;
; <SM3> 11/6/92 SWC Rewrote all the routines (read: cleanup).
; <SM2> 10/28/92 SWC Changed INCLUDEs to a LOAD of StandardEqu.d.
; <6> 11/15/91 JL Changed MoveA.L RBuffer(A6) to MoveA.L PmgrRPtr(A0) after the
; trap call to put an address in A0 instead of data.
; <5> 11/12/91 JL stb: allocated receive buffers for BatteryStatus, ModemStatus,
; and GetWUTime.
; <4> 1/22/91 ag MSH: Moved Power Manager command equates directly into this file
; from PowerEqu.a to make them private.
; <3> 1/22/91 ag MSH - Moved Power Manager command equates directly into this
