Packet sending and reception semantics for simulated network device support using either TCP or UDP transport.
Input character rates reflect the natural character arrival time based on the line speed.
#### Video Display Capabilities
Added support for monochrome displays with optional keyboards and mice.
The VAXstation QVSS device (VCB01) simulation uses this capability.
Host platforms which have libSDL available can leverage this functionality.

ON Traps can specify any status value from the following list: NXM, UNATT, IOERR, CSUM, FMT, NOATT, OPENERR, MEM, ARG, STEP, UNK, RO, INCOMP, STOP, TTIERR, TTOERR, EOF, REL, NOPARAM, ALATT, TIMER, SIGERR, TTYERR, SUB, NOFNC, UDIS, NORO, INVSW, MISVAL, 2FARG, 2MARG, NXDEV, NXUN, NXREG, NXPAR, NEST, IERR, MTRLNT, LOST, TTMO, STALL, AFAIL. These values can be indicated by name or by their internal numeric value (not recommended).
Interactions with ASSERT command and "DO -e":
DO -e is equivalent to SET ON, which by itself it equivalent to "SET ON; ON ERROR RETURN".
ASSERT failure have several different actions:
If error trapping is not enabled then AFAIL causes exit from the current do command file.
If error trapping is enabled and an explicit "ON AFAIL" action is defined, then the specified action is performed.
If error trapping is enabled and no "ON AFAIL" action is defined, then an AFAIL causes exit from the current do command file.

The "!" command (execute a command on the local OS), now returns the command's exit status as the status from the "!" command. This allows ON conditions to handle error status responses from OS commands and act as desired.

If you are interested in using a simulator with Ethernet networking support (i.e. one of the VAX simulators or the PDP11), then you should make sure you have the correct networking components available. The instructions in https://github.com/simh/simh/blob/master/0readme_ethernet.txt describe the required steps to get ethernet networking components installed and how to configure your environment.
See the 0readme_ethernet.txt file for details about the required network components for your platform. Once your operating system has the correct networking components available the following command will build working simulators:
