18-Mar-12 RMS Removed unused reference to sim_switches (Dave Bryan)
22-Dec-11 JDB [local fix 3] Fixed bug with anchored halt string matching
07-Dec-11 MP Added sim_ttisatty to support reasonable behaviour (i.e.
avoid in infinite loop) in the main command input
loop when EOF is detected and input is coming from
a file (or a null device: /dev/null or NUL:) This may
happen when a simulator is running in a background
process.
17-Apr-11 MP Cleaned up to support running in a background/detached
process
20-Jan-11 MP Fixed support for BREAK key on Windows to account
for/ignore other keyboard Meta characters.
18-Jan-11 MP Added log file reference count support
17-Jan-11 MP Added support for a "Buffered" behaviors which include:
- If Buffering is enabled and Telnet is enabled, a
telnet connection is not required for simulator
operation (instruction execution).
- If Buffering is enabled, all console output is
written to the buffer at all times (deleting the
oldest buffer contents on overflow).
- when a connection is established on the console
telnet port, the whole contents of the Buffer is
presented on the telnet session and connection
will then proceed as if the connection had always
been there.
This concept allows a simulator to run in the background
and when needed a console session to be established.
The "when needed" case usually will be interested in
what already happened before looking to address what
to do, hence the buffer contents being presented.
28-Dec-10 MP Added support for BREAK key on Windows
30-Sep-06 RMS Fixed non-printable characters in KSR mode
22-Jun-06 RMS Implemented SET/SHOW PCHAR
31-May-06 JDB Fixed bug if SET CONSOLE DEBUG with no argument
22-Nov-05 RMS Added central input/output conversion support
05-Nov-04 JDB [local fix 3] Added SET/SHOW CONSOLE HALT=<string> command
[local fix 3] Added SET/SHOW CONSOLE RESPONSE=<string> command
[local fix 3] Added SET/SHOW CONSOLE DELAY=<n> command, halt svc
05-Nov-04 RMS Moved SET/SHOW DEBUG under CONSOLE hierarchy
28-Oct-04 JDB Fixed SET CONSOLE to allow comma-separated parameters
20-Aug-04 RMS Added OS/2 EMX fixes (Holger Veit)
14-Jul-04 RMS Revised Windows console code (Dave Bryan)
28-May-04 RMS Added SET/SHOW CONSOLE
RMS Added break, delete character maps
02-Jan-04 RMS Removed timer routines, added Telnet console routines
RMS Moved console logging to OS-independent code
25-Apr-03 RMS Added long seek support (Mark Pizzolato)
Added Unix priority control (Mark Pizzolato)
24-Sep-02 RMS Removed VT support, added Telnet console support
Added CGI support (Brian Knittel)
Added MacOS sleep (Peter Schorn)
14-Jul-02 RMS Added Windows priority control (Mark Pizzolato)
20-May-02 RMS Added Windows VT support (Fischer Franz)
01-Feb-02 RMS Added VAX fix (Robert Alan Byer)
19-Sep-01 RMS More MacOS changes
31-Aug-01 RMS Changed int64 to t_int64 for Windoze
20-Jul-01 RMS Added Macintosh support (Louis Chretien, Peter Schorn, Ben Supnik)
15-May-01 RMS Added logging support
05-Mar-01 RMS Added clock calibration support
08-Dec-00 BKR Added OS/2 support (Bruce Ray)
18-Aug-98 RMS Added BeOS support
13-Oct-97 RMS Added NetBSD terminal 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_set_cons_buff - set console buffered
sim_set_cons_unbuff -set console unbuffered
sim_set_cons_log - set console log
sim_set_cons_nolog - set console nolog
sim_show_cons_buff - show console buffered
sim_show_cons_log - show console log
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_ttisatty - called to determine if running interactively
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

/* Check for a console halt.
The console halt string match mode may be specified as anchored (-a) or
unanchored, and immediate (-i) or deferred. An anchored string must match at
the start of the output buffer; an unanchored string may match anywhere. An
immediate match halts as soon as the last character of the match string is
seen in the output stream and may occur multiple times per line; a deferred
match halts only after the trailing line feed character is output and occurs
only once, regardless of the number of times the match string appears in the
output stream.
Once a deferred match has occured, or an anchored match has failed, no
further match checks are made on the current line.
An immediate, anchored match halts only once when the halt string first
matches, even if the match string also occurs later in the line. For
example, if the match string is "ABC" and the output characters are
"ABC-ABC", the halt occurs after the first "C" is output but NOT after the
second "C" is output, even though the halt string still matches the start of
the output buffer. The second halt would occur if the immediate match was
unanchored.
To summarize the match modes:
- unanchored, deferred: halt once if match occurs anywhere in the line
- unanchored, immediate: halt each time the match occurs anywhere in the line
- anchored, deferred: halt once if match occurs at the start of the line
- anchored, immediate: halt once if match occurs at the start of the line
Implementation Notes:
1. This routine should be called only when console halts are enabled.
2. The passed character is checked against the current match character. If
it matches, the match string pointer is advanced. If the end of the
match string is reached, match success is indicated and further match
checks are suppressed until the console halt occurs, which may be
immediately or at the end of the line, depending on whether the "-i"
switch was used.
3. If the character does not match, and the match is anchored, further match
checks are suppressed until the start of the next line.
4. If the character does not match, and the match is unanchored, a check is
made to see if any characters have matched. If not, then substrings need
not be checked. Otherwise, the output stream is searched for substrings
of the match string. For example, if the match string is "GAGAX" and the
output characters are "GAGAG", then the match fails on the fifth
character. However, the last three characters output match the leading
substring "GAG" of the match string, so the match pointer is reset to
point at the fourth character, rather than the second. Then, if an "AX"
is subsequently output, the match will succeed.
5. Searching for the longest substring that matches the output stream would
appear to require a history buffer. However, the fact that all of the
prior output characters until the current one have matched means that the
match string itself IS a history of the output stream. We need only
search for substrings that equal the substring of the match string that
ends with the last-matched character.
6. The search starts with the longest possible substring and then attempts
shorter and shorter substrings until either a match occurs or no
substring matches. In the first case, the match pointer is reset
appropriately, and partial matching continues. In the second, the match
pointer is reset to the beginning of the match string, and a new match is
sought.
