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.
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.

Fixed Ethernet formatting of open device names
Fixed serial generic naming to accomodate for the fact that an OS list of serial devices might not include devices which are already opened.
Fixed do file line numbers in messages to properly track after nested do command files.
Generalized do file command echoing to always include the do file line number
Fixed SET ON which was broken when SET ON INHERIT and SET ON NOINHERIT was added.
Fixed ON INHERIT behaviors for global ini files.
Added SET QUIET and SET NOQUIET commands
Added -Q flag to DO command file processing which sets quiet mode while that command file executes
Changed generic include file name to simh.ini from simh.rc to be consistent with other include files
Changed generic include file to come from the user HOME or HOMEPATH directory and if not found, the current default directory
Fixed format string used to provide quotes around arguments containing spaces while producing %* expansion.
Fixed return from do_cmd to return the status from the last command executed
It also modifies the HP 2100 and PDP11 multiplexers to add serial support as demonstrations of the capability that, one day, might be extended to all simulators. I have tested the HP support, but I relied on Holger Veit to test the DEC stuff, so I can't guarantee that it works. I also relied on Holger to test under Linux, so the same caveat applies.
The changes needed in the device simulators are relatively small. For example, if you look at the patches for "hp2100_baci.c", you'll note that most of them are documentation changes. The only things of note are:
- an expansion of the TMXR initializer
- additional code in the "attach" routine to try attaching a serial port
if attaching a socket fails
- additional code in the "detach" routine for the same reasons
The HP MPX device (hp2100_mpx.c) needs a tiny bit of additional support from the ATTACH and DETACH commands. Specifically, SCP was modified to set a flag ("sim_unit_ref") to indicate whether ATTACH MPX or ATTACH MPX0 was done, i.e., to differentiate between a device and a unit attach (recall that SCP treats these as both referring to unit 0). This is needed because the socket attaches (logically) to the device, whereas a serial port attaches to a line. Without this flag, the attach routine cannot differentiate between ATTACH MPX and ATTACH MPX0, as the distinction is lost by the time the VM's attach routine is called. This support isn't needed for the HP MUX device because the socket attaches to a different device than the lines do.
MPX also requires a bit more work due to the capability to mix serial and Telnet lines on the same multiplexer (BACI is a single-line terminal device).
The attached PDF contains revisions to the "Writing a Simulator for the SIMH System" publication that documents the additions and changes to the multiplexer library for serial port support. User documentation for serial port support currently exists only in the initial comments in "sim_tmxr.c"; I will add the appropriate text to the "SIMH User's Guide" if we decide to add this to the release version.
