Fix building under Visual Studio on Windows XP.
Fixed Remote Console to tolerate bare LF as a line terminator and enhanced the tmxr debug output for special characters
Added more extensive debug output of tmxr telnet parameter and data
Added remote console support when a persistent console log is not enabled.
Added a more unique naming paradigm for remote console temporary log files to avoid potential collisions when multiple simulators may be running concurrently
Added documentation for the Remote Console capabilities
Fixed compile and operational behaviors when running with SIM_ASYNCH_CLOCKS enabled
Added separate debugging ability to trace line connect/disconnect activities to better debug virtual null modem cable activities.
Fixes for stable operation with SIM_ASYNCH_CLOCKS defined
Tolerate race condition which results in spurious timer thread wakeups which were causing the timer thread to exit. (SIM_ASYNCH_CLOCKS)
Fixed formatting error
Reworked all asynch queues to always link using the unit a_next field instead of the next field.
Compiler suggested cleanups
Compiler suggested fix.
Cleanup for build support on HP-UX for both 32bit and 64bit builds with gcc and the HP C compilers.
Describe the proper build command for HP-UX
Fix potential remote console memory leak
Enhanced Remote Console support to allow two separate command processing modes.

 1) Single Command Mode:  commands are processed between simulated instructions once CR is received.
 2) Multiple Command Mode: commands are initiated with the WRU character (usually *E) which suspends simulation execution and commands are processed until a CONTINUE command is entered (or automatically provided if the SET REMOTE TIMEOUT=seconds interval has elapsed).
Avoid noisy log messages in Remote Console activities.
Avoid passing negative values (i.e. signed characters) to isprint() which is not happy with doing this on some platforms.
