02cb620c9b Change to support serial ports on multiplexer devices without any changes to existing multiplexer device emulation code.
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

bc36e9dde5 Adds serial port support to the multiplexer library.
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.

9c4779c061 Notes For V3.8
The makefile now works for Linux and most Unix's. Howevr, for Solaris
and MacOS, you must first export the OSTYPE environment variable:

> export OSTYPE
> make

Otherwise, you will get build errors.

1. New Features

1.1 3.8-0

1.1.1 SCP and Libraries

- BREAK, NOBREAK, and SHOW BREAK with no argument will set, clear, and
  show (respectively) a breakpoint at the current PC.

1.1.2 GRI

- Added support for the GRI-99 processor.

1.1.3 HP2100

- Added support for the BACI terminal interface.
- Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions.

1.1.4 Nova

- Added support for 64KW memory (implemented in third-party CPU's).

1.1.5 PDP-11

- Added support for DC11, RC11, KE11A, KG11A.
- Added modem control support for DL11.
- Added ASCII character support for all 8b devices.

1.2 3.8-1

1.2.1 SCP and libraries

- Added capability to set line connection order for terminal multiplexers.

1.2.2 HP2100

- Added support for 12620A/12936A privileged interrupt fence.
- Added support for 12792C eight-channel asynchronous multiplexer.

2. Bugs Fixed
