The 68HC08 monitor was supplied by BiPom Electronics, and is derived in
part from my 68HC12 monitor sources. No documentation is available for
this monitor other than the source code comments. Here is a list of
commands taken from that source:

    BS <addr>               Set breakpoint (0000=remove)
    CF <addr>,<addr>        Clear Flash Memory
    CR <reg> <data>         Change register
    DB                      Display breakpoint

    DM <addr>,<addr>        Display memory in hex dump format
    DR                      Display processor registers
    EM <addr>               Edit memory(RAM),  "SPACE" exit
    EF <addr>               Edit memory(FLASH),"SPACE" exit
    FM <addr>,<addr> <data> Fill memory(RAM)
    FF <addr>,<addr> <data> Fill memory(FLASH)
    G  <addr>               Go (execute program)
