- *  Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB	    Set baud rate to BB..BB		   OK or BNN, then sets
- *							   baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer.  '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host:                  Reply:
- * $m0,10#2a               +$00010203040506070809101112131415#42

- *  Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *  Based on sparc-stub.c, it's modified for SPARClite Debug Unit hardware
- *  breakpoint support to create sparclite-stub.c, by Kung Hsu, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
- *    ?             What was the last sigval ?             SNN   (signal NN)
- *
- *    bBB..BB	    Set baud rate to BB..BB		   OK or BNN, then sets
- *							   baud rate
- *
- * All commands and responses are sent with a packet which includes a
- * checksum.  A packet consists of
- *
- * $<packet info>#<checksum>.
- *
- * where
- * <packet info> :: <characters representing the command or response>
- * <checksum>    :: < two hex digits computed as modulo 256 sum of <packetinfo>>
- *
- * When a packet is received, it is first acknowledged with either '+' or '-'.
- * '+' indicates a successful transfer.  '-' indicates a failed transfer.
- *
- * Example:
- *
- * Host:                  Reply:
- * $m0,10#2a               +$00010203040506070809101112131415#42

- *  Header: remcom.c,v 1.34 91/03/09 12:29:49 glenne Exp $
- *
- *  Module name: remcom.c $
- *  Revision: 1.34 $
- *  Date: 91/03/09 12:29:49 $
- *  Contributor:     Lake Stevens Instrument Division$
- *
- *  Description:     low level support for gdb debugger. $
- *
- *  Considerations:  only works on target hardware $
- *
- *  Written by:      Glenn Engel $
- *  ModuleState:     Experimental $
- *
- *  NOTES:           See Below $
- *
- *  Modified for SPARC by Stu Grossman, Cygnus Support.
- *  Based on sparc-stub.c, it's modified for SPARClite Debug Unit hardware
- *  breakpoint support to create sparclite-stub.c, by Kung Hsu, Cygnus Support.
- *
- *  This code has been extensively tested on the Fujitsu SPARClite demo board.
- *
- *  To enable debugger support, two things need to happen.  One, a
- *  call to set_debug_traps() is necessary in order to allow any breakpoints
- *  or error conditions to be properly intercepted and reported to gdb.
- *  Two, a breakpoint needs to be generated to begin communication.  This
- *  is most easily accomplished by a call to breakpoint().  Breakpoint()
- *  simulates a breakpoint by executing a trap #1.
- *
- *************
- *
- *    The following gdb commands are supported:
- *
- * command          function                               Return value
- *
- *    g             return the value of the CPU registers  hex data or ENN
- *    G             set the value of the CPU registers     OK or ENN
- *    P             set the value of a single CPU register OK or P01 (???)
- *
- *    mAA..AA,LLLL  Read LLLL bytes at address AA..AA      hex data or ENN
- *    MAA..AA,LLLL: Write LLLL bytes at address AA.AA      OK or ENN
- *
- *    c             Resume at current address              SNN   ( signal NN)
- *    cAA..AA       Continue at address AA..AA             SNN
- *
- *    s             Step one instruction                   SNN
- *    sAA..AA       Step one instruction from AA..AA       SNN
- *
- *    k             kill
- *
