Some devices have dedicated units that perform various independent
functions (often timing) that are independent of the primary device unit
which is ATTACHed. This services to help interpret debug information
that may be produced.
sim> SET XQ MAC=aa:bb:cc:dd:ee:ff{/bits}{>filespec}
where:
- all of the aa:bb:cc:dd:ee:ff values must be hex digits
- bits is the number of bits which are to be taken from the supplied
MAC aa:bb:cc:dd:ee:ff with legal values from 16 to 48 and a default
of 48 bits.
- filespec specifies a file which contains the MAC address to be used
and if it doesn't exist an appropriate generated address will be stored
in this file and a subsequent SET MAC invocation specifying the same
file will use the value stored in the file rather than generating a new
MAC.
As discussed in #317
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.
Most simulators can now also be compiled with a C++ compiler without
warnings.
Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.
When packets arrive which require multiple receive buffers to deliver, the
full packet size is reported in the MLEN field of the final receive descriptor
used (the one with the ENF bit set). Previously, correct behavior only
happened when the full packet fit into a single receive buffer. This problem
was reported and the detail identified by Johnny Billquist.
Make sure to properly support multiple receive buffers by correctly setting the data length read and the appropriate buffer descriptor status bits for each buffer descriptor that is used to hold a packet.
Migrated the XQ help to the hierarchical help model. This is a work in progress which will eventually merge much from 0readme_ethernet.txt into the device help.
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.
Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().
Show IOSPACE doesn't always get the number of devices right due to device creativity.
o The distinction between UNIT and DEVICE has blurred
o MUX devices merge several physical devices into one device/unit
o Dynamic device sizing has made things more volatile.
This edit solves the problem for SHOW IOSPACE by adding an (optional) word to the DIBs.
The word contains the amount of IO space consumed by each instance of the physical device that's being emulated.
E.G., if it's a DZ11, the device is the DZ11 module, or 8 lines, even though the MUX device may support 32.
This enables SHOW IOSPACE to determine the number of physical devices being emulated, which is what folks need when configuring software. The word may have other uses - in a generic dynamic device sizing routine - which is why the amount of IOSPACE per device was chosen rather than the 'number of physical devices.'
The edit should not make any existing device regress. If the new word (ulnt) is zero (not initialized), SHOW IOSPACE will default to the number of units in the device, or if there's no device (CPUs), 1 as before. If it is present, the number of devices is the calculated as total allocation/allocation-per-device.
The edit updates all the devices that seem to require this treatment, and all the processors that define the UNIBUS/QBUS DIBs.
Fixed auto configure bugs which didn't allow Fixed CSR Addresses or Fixed Vectors to be set using the auto configure information.
Fixed display of address and vectors to indicate that the assigned address and/or vector is in the floating set.
Added extended definitions to the auto configure table to reflect all known potential static and floating and static addresses as of VMS V5.5-2
Changed the name of the VAX 11/780 console floppy device name to RXC from RX (which collides with a Unibus name for the RX11).
The makefile now works for Linux and most Unix's. However, for Solaris
and MacOS, you must first export the OSTYPE environment variable:
> export OSTYPE
> make
Otherwise, you will get build errors.

The source set has been extensively overhauled. For correct
viewing, set Visual C++ or Emacs to have tab stops every 4
characters.
1. New Features
1.1 3.5-0
1.1.1 All Ethernet devices
- Added Windows user-defined adapter names (from Timothe Litt)
1.1.2 Interdata, SDS, HP, PDP-8, PDP-18b terminal multiplexors
- Added support for SET <unit>n DISCONNECT
1.1.3 VAX
- Added latent QDSS support

1.1.4 PDP-11

1.2 3.5-1
No new features
1.3 3.5-2
1.3.1 All ASCII terminals
- Most ASCII terminal emulators have supported 7-bit and 8-bit
operation; where required, they have also supported an upper-
case only or KSR-emulation mode. This release adds a new mode,
7P, for 7-bit printing characters. In 7P mode, non-printing
characters in the range 0-31 (decimal), and 127 (decimal), are
automatically suppressed. This prevents printing of fill
characters under Windows.
The printable character set for ASCII code values 0-31 can be
changed with the SET CONSOLE PCHAR command. Code value 127
(DELETE) is always suppressed.
1.3.2 VAX-11/780
- First release. The VAX-11/780 has successfully run VMS V7.2. The
commercial instructions and compatability mode have not been
extensively tested. The Ethernet controller is not working yet
and is disabled.
