20-Mar-12 MP Fixes to "SHOW <x> SHOW" commands
06-Jan-12 JDB Fixed "SHOW DEVICE" with only one enabled unit (Dave Bryan)
25-Sep-11 MP Added the ability for a simulator built with
SIM_ASYNCH_IO to change whether I/O is actually done
asynchronously by the new scp command SET ASYNCH and
SET NOASYNCH
22-Sep-11 MP Added signal catching of SIGHUP and SIGTERM to cause
simulator STOP. This allows an externally signalled
event (i.e. system shutdown, or logoff) to signal a
running simulator of these events and to allow
reasonable actions to be taken. This will facilitate
running a simulator as a 'service' on *nix platforms,
given a sufficiently flexible simulator .ini file.
20-Apr-11 MP Added expansion of %STATUS% and %TSTATUS% in do command
arguments. STATUS is the numeric value of the last
command error status and TSTATUS is the text message
relating to the last command error status
17-Apr-11 MP Changed sim_rest to defer attaching devices until after
device register contents have been restored since some
attach activities may reference register contained info.
29-Jan-11 MP Adjusted sim_debug to:
- include the simulator timestamp (sim_gtime)
as part of the prefix for each line of output
- write complete lines at a time (avoid asynch I/O issues).
