MultiPort/LT Gateway Code Commands
3.3.6.
Debugging Commands
3.3.6.1. Control P - Panic
The "Control P" command causes an "Operator Panic". In conjunction with
Debug switch "d1000" it puts the gateway into the MultiPort/LT gateway code
command mode from which its internal state can be examined. It will produce
the message:
PANIC! operator
trapsp 000000 from 100CE6 sr 2700
abregs[00..] 00000000 00000025 00000000 00000000
abregs[04..] 00000000 00000000 00000076 00000050
abregs[08..] 0010ACDE 001448F8 00114184 0011419C
abregs[12..] 0004003E 0004003C 0011D0B4 0011D098
...cmd>
3.3.6.2. $ - Abort Save Registers
When the MultiPort/LT Panics, it saves the current 68010 D0 to D7 and A0 to A7
CPU registers in a structure referred to as the abregs. These are printed out
with the Panic message, but can be printed out at any later time. This command
is only useful in association with Debug switch "d1000". "Trapsp" is the value
of the Stack pointer at the time of the trap, "from" is the program counter and
"sr" the processor status register. The following is an "empty" printout - no
panics having occurred:
trapsp 000000 from 000000 sr 0000
abregs[00..] 00000000 00000000 00000000 00000000
abregs[04..] 00000000 00000000 00000000 00000000
abregs[08..] 00000000 00000000 00000000 00000000
abregs[12..] 00000000 00000000 00000000 00000000
