Bob Supnik a9fd3dd518 Notes For V3.8 
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.

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.

1.3 3.8-2

1.3.1 SCP and libraries

- Added line history capability for *nix hosts.
- Added "SHOW SHOW" and "SHOW <dev> SHOW" commands.

1.3.2 1401

- Added "no rewind" option to magtape boot.

1.3.3 PDP-11

- Added RD32 support to RQ
- Added debug support to RL

1.3.4 PDP-8

- Added FPP support (many thanks to Rick Murphy for debugging the code)

1.3.5 VAX-11/780

- Added AUTORESTART switch support, and VMS REBOOT command support

25-Jan-97 RMS Added POSIX terminal I/O support
02-Jan-97 RMS Fixed bug in sim_poll_kbd
This module implements the following routines to support terminal I/O:
sim_poll_kbd - poll for keyboard input
sim_putchar - output character to console
sim_putchar_s - output character to console, stall if congested
sim_set_console - set console parameters
sim_show_console - show console parameters
sim_tt_inpcvt - convert input character per mode
sim_tt_outcvt - convert output character per mode
sim_ttinit - called once to get initial terminal state
sim_ttrun - called to put terminal into run state
sim_ttcmd - called to return terminal to command state
sim_ttclose - called once before the simulator exits
sim_os_poll_kbd - poll for keyboard input
sim_os_putchar - output character to console
The first group is OS-independent; the second group is OS-dependent.
The following routines are exposed but deprecated:
sim_set_telnet - set console to Telnet port
sim_set_notelnet - close console Telnet port
sim_show_telnet - show console status
