-// OBSOLETE  *  Module name: remcom.c $
-// OBSOLETE  *  Revision: 1.34 $

-// OBSOLETE  *  Description:     low level support for gdb debugger. $
-// OBSOLETE  *
-// OBSOLETE  *  Considerations:  only works on target hardware $
-// OBSOLETE  *
-// OBSOLETE  *  Written by:      Glenn Engel $
-// OBSOLETE  *  ModuleState:     Experimental $
-// OBSOLETE  *
-// OBSOLETE  *  NOTES:           See Below $
-// OBSOLETE  *
-// OBSOLETE  *  Modified for SPARC by Stu Grossman, Cygnus Support.
-// OBSOLETE  *  Based on sparc-stub.c, it's modified for SPARClite Debug Unit hardware
-// OBSOLETE  *  breakpoint support to create sparclite-stub.c, by Kung Hsu, Cygnus Support.
-// OBSOLETE  *
-// OBSOLETE  *  This code has been extensively tested on the Fujitsu SPARClite demo board.
-// OBSOLETE  *
-// OBSOLETE  *  To enable debugger support, two things need to happen.  One, a
-// OBSOLETE  *  call to set_debug_traps() is necessary in order to allow any breakpoints
-// OBSOLETE  *  or error conditions to be properly intercepted and reported to gdb.
-// OBSOLETE  *  Two, a breakpoint needs to be generated to begin communication.  This
-// OBSOLETE  *  is most easily accomplished by a call to breakpoint().  Breakpoint()
-// OBSOLETE  *  simulates a breakpoint by executing a trap #1.
-// OBSOLETE  *
-// OBSOLETE  *************
-// OBSOLETE  *
-// OBSOLETE  *    The following gdb commands are supported:
-// OBSOLETE  *
-// OBSOLETE  * command          function                               Return value
-// OBSOLETE  *
-// OBSOLETE  *    g             return the value of the CPU registers  hex data or ENN
-// OBSOLETE  *    G             set the value of the CPU registers     OK or ENN
-// OBSOLETE  *    P             set the value of a single CPU register OK or ENN
-// OBSOLETE  *
-// OBSOLETE  *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
-// OBSOLETE  *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
-// OBSOLETE  *
-// OBSOLETE  *    c             Resume at current address              SNN   ( signal NN)
-// OBSOLETE  *    cAA..AA       Continue at address AA..AA             SNN
-// OBSOLETE  *
-// OBSOLETE  *    s             Step one instruction                   SNN
-// OBSOLETE  *    sAA..AA       Step one instruction from AA..AA       SNN
-// OBSOLETE  *
-// OBSOLETE  *    k             kill
-// OBSOLETE  *
-// OBSOLETE  *    ?             What was the last sigval ?             SNN   (signal NN)
-// OBSOLETE  *
-// OBSOLETE  * All commands and responses are sent with a packet which includes a
-// OBSOLETE  * checksum.  A packet consists of
-// OBSOLETE  *
-// OBSOLETE  * $<packet info>#<checksum>.
-// OBSOLETE  *
-// OBSOLETE  * where
-// OBSOLETE  * <packet info> :: <characters representing the command or response>
-// OBSOLETE  * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
-// OBSOLETE  *
-// OBSOLETE  * When a packet is received, it is first acknowledged with either '+' or '-'.
-// OBSOLETE  * '+' indicates a successful transfer.  '-' indicates a failed transfer.
-// OBSOLETE  *
-// OBSOLETE  * Example:
-// OBSOLETE  *
-// OBSOLETE  * Host:                  Reply:
-// OBSOLETE  * $m0,10#2a               +$00010203040506070809101112131415#42
