scp.c,scp.h - Gave priority to a command message handler to determine what values result in displayed messages and exported run_cmd_message for use by simulators which add simulator specific BOOT commands which leverage the run_cmd logic and should also leverage the run_cmd_message for message display
VAX/vax610_sysdev.c, vax730_sys.c, vax750_cmi.c, vax780_sbi.c - Added BOOT command message dispatch to run_cmd_message for simulators which perform preprocessing on BOOT activities but otherwise then dispatch to run_cmd.

sim_serial.c
- Fixed error message printing when retry is merely needed
sim_tmxr.c
- Fixed parsing to properly recognize a listen port argument of "nnn;notelnet".
- Fixed buffer wrap output condition.
Added support for per line tcp listen ports.
Added support for per line outgoing tcp/telnet connections.
Removed DEV_NET from pdp11_dz and pdp11_vh emulators to allow proper restore of
Hello,
I fixed the show/set default commands and tested on the following host
platform: OSX(x64), Linux(arm), FreeBSD(x86), Windows(x64),
OpenVMS(VAX).
The commands are very simple and the code is the same for all the *nix
and VMS, and it is a little different for Windows.

scp.c, scp.h
- Change the sim_clock_queue event list to be terminated by the value QUEUE_LIST_END instead of NULL. This allows easy determination of whether a unit is on a list since when it is not on a list the next pointer is NULL.
- standardized the usage of UPDATE_SIM_TIME
- Added support for internal/pseudo devices to support the TIMER and CON-TEL pseudo devices (to enable and disable debugging)
- Reverted to the prior "SET CONSOLE DEBUG" command semantics since the console debug can be manipulated via the generic "SET <dev> DEBUG" command (i.e. SET CON-TEL DEBUG=TRC;XMT;RCV)
- Changed "SHOW TIMERS" to "SHOW CLOCKS" to display the current calibrated timer information
- Added sim_is_active_bool API to return the boolean active status avoiding the potential work walking the list when most callers aren't interested in the event firing time
- Fixed run_boot_prep to properly record the not queued status of any units which are removed from the sim_clock_queue during initialization
- Added display of DEBUG, NODEBUG options to the SHOW SHOW command
sim_timer.c, sim_timer.h
- Added asynchronous timer capabilities with support for calibration and idling
- Added internal/pseudo device to support debugging of Idle, Calibration and asynch timer activites.
- Added suppression of timer calibration when idling has occurred
sim_tmxr.c, sim_tmxr.h
- Added tmxr_activate_after and macro definition for sim_activate_after to invoke it for proper behavior with multiplexer devices
- Added all polling units to the standard timer queue when dropping back to the simulator command prompt to accommodate the potential to disable asynch mode
- Fixed synchronization to operate with pthread synchronized asynch queue and proper stopping of poll when dropping back to the simulator command prompt
- Fixed calls to select to have a timeout with properly ranged tv_usec values and dealt with possible EINTR return from select
sim_console.c, sim_console.h
- Changed internal/pseudo console telnet device name to CON=TEL
- Reverted to the prior "SET CONSOLE DEBUG" command semantics since the console debug can be manipulated via the generic "SET <dev> DEBUG" command (i.e. SET CON-TEL DEBUG=TRC;XMT;RCV)
- Fixed synchronization to operate with pthread synchronized asynch queue and proper stopping of poll when dropping back to the simulator command prompt
- Fixed calls to select to have a timeout with properly ranged tv_usec values
sim_defs.h
- Added necessary unit fields to support asynchronous timing activities
- Added asynchronous macros to support async timing activities
- Fixed asynch pthread only macros (not using AIO_INTRINSICS).
- Fixed the definition of the UDATA macro which was never adjusted to accommodate the insertion of 2 extra fields in the unit structure and thus made the initialization of the unit wait field meaningless.
- Changed the NOQUEUE_WAIT value from 10000 to 1000000. This is only used when the sim_clock_queue is empty, which normally never happens on any simulator since they all have clocks and/or other frequently polling devices. With asynchronous multiplexer and timing support the queue is often empty and this value is then used when calculating idling delays. If it is too small, idling will be inefficient. Being large should not be a problem otherwise.
Interdata/id16_cpu.c
- removed test of sim_idle_enab before calling sim_idle
Interdata/id32_cpu.c
- removed test of sim_idle_enab before calling sim_idle
vax/vax_cpu.c
- removed test of sim_idle_enab before calling sim_idle
vax/vax_stddev.c
- converted CLK device to use the internal timer service API sim_activate_after to leverage asynchronous timing when available
- Added support to allow proper building of ROM dependent modules if the ROM image file is missing but the desired ROM image include file exists and has the correct/expected contents.
- Added support to help new ROMs to be added to the set of ROMs which are translated/tested.
- Added command Usage to program which is displayed if invoked with /? or /help Usage displays the current set of ROM images which are known.
