- The following options are also supported:
-
- -snnn set the initial system load (ISL) start address to
- nnn in the volume label. This is useful when
- building boot media for Series 700/800 systems.
-
- -lnnn specifies the length in bytes of the ISL code in
- the LIF volume.
-
- -ennn set the ISL entry point to nnn bytes from the
- beginning of the ISL. For example, specifying -
- e3272 means that the ISL entry point is 3272
- (decimal) bytes from the beginning of the ISL
- object module.
-
- -Knnn forces the directory start location to be the
- nearest multiple of nnn x 1024 bytes from the
- beginning of the volume. This is necessary for
- booting Series 700/800 systems from LIF media.
-
- -n xxx Sets the volume name to be xxx.

- *
- * Description: low level support for gdb debugger. $
- *
- * Considerations: only works on target hardware $
- *
- * NOTES: See Below $
- *
- * 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
-
-
- *************
- *
- * 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
