C-KERMIT 5A(190) EDIT HISTORY, 5 AUG 93 - 4 OCT 94.

In ckutio.c, corrected a typo that might have prevented setting a serial
port's speed to 57600 bps.  Also, consistently added support for 57600 and
115200 bps if symbols for those speeds are defined.  (But this is still an
issue for the command processor, which does not have access to
system-dependent symbols like this).  ckutio.c 5A(111), 5 Aug 93.

From Bill Glass - fixed a statistics counter (file bytes) that was still
counting some non-file material (contents of server command packets) in
the decode() function.  ckcfns.c 5A(090), 6 Aug 93.

Added types to all functions in VMS-specific modules, CKVFIO.C and CKVTIO.C
(CKVCON was already OK) to pacify the new, stricter Alpha AXP (DEC C)
compilers.  CKVFIO.C 5A(056), CKUTIO.C 5A(101), 8 Aug 93.

Added patches to enable SET FLOW RTS/CTS in Linux, originally from Rick
Sladkey, [e-mail].  Depends on symbol "linux".  ckcdeb.h, ckutio.c.

Terry Kennedy pointed out that VMS C-Kermit follows FILE TYPE when
TRANSMITting, even if it is IMAGE or LABELED.  Changed the TRANSMIT command
to treat any of the system-specific binary modes (IMAGE, LABELED, MACBINARY,
etc) as ordinary binary mode, i.e. saved and restored the "binary" variable
in the TRANSMIT command.  ckuus4.c, 10 Aug 93.

Shinichi Sakata <[e-mail]> discovered that if an "application
file" (a file whose name is given as the first command-line argument) contains
a CD command, that C-Kermit would, after finishing the application file,
act as if it had been given an invalid command-line argument.  Fixed by adding
yet another flag, cfilef - set in ckcmai.c, tested in ckuusy.c.  10 Aug 93.

From Rob Weiner <[e-mail]>, a new makefile entry,
sys5r4sxtcpc, for CONSENSYS System V R4.2-1 with TCP/IP and curses.  makefile.
12 Aug 93.

From Rich Sladkey <[e-mail]>: (1) fix prototype of ttrpid() in
ckutio.c; (2) fix fixes to Linux hardware flow control.  It's still ugly
internally, but cleaning up the hardware flow control code would be a major
undertaking due to the geometrically expanding combinations of flow control
settings and different APIs for setting them.  ckutio.c 5A(112) 22 Aug 93.

Added conditional compilation support for system-wide init file.  If the
compile-time symbol CK_SYSINI is defined (to be a character string in
doublequotes), it is taken as the file specification of the initialization
file, to be used instead of the built-in default.  This can be absolute or
relative, so it can point to a single system-wide file, or to something like
~/.kermrc (UNIX) or SYS$LOGIN:CKERMIT.INI (VMS) to indicate the user's own.
If it is system wide, it can (and probably should) still "chain" to the user's
own initialization file, by ending (or starting, depending on the desired
precedence) with a command like:

  if exist \v(home)ckermit.ini take \v(home)ckermit.ini

ckuus5.c, 10 Sep 93.

Fixes for VMS C-Kermit, all in CKVTIO.C:
 * 058 27-Sep-93 HG   Fix for real the SHARE issue when allocating terminal
 *		      by dropping SHARE before trying to assign the channel.
 * 059  7-Oct-93 mlo  Added support for CMU-OpenVMS/IP ("CMU/Tek").  Requires
 *                    CMU-OpenVMS/IP sockets library, also by mlo.
 * 060  9-Oct-93 HG   Fix improper call to vms_assign_channel in edit 058,
 *                    noticed by [e-mail].
 * 061  9-Oct-93 fdc  For some reason, conbin() was turning off flow control.
 *                    This caused massive data loss during CONNECT mode when
 *                    running C-Kermit from a low-speed connection through
 *                    a DECserver.  Now conbin() leaves the console flow
 *                    control setting alone.
 * 062 10-Oct-93 ttj  Correcting parameters to time() and ctime(). Was long,
 *                    is now time_t (pointers).  Made prototype for
 *                    vms_assign_channel and caught an erroneous function call.

Plus CMU/Tek TCP/IP support for VMS C-Kermit from Mike O'Malley at DEC
<[e-mail]>; minor source changes to CKCNET.C, CKCNET.H,
CKUUS4.C, and (noted above) CKVTIO.C.

Plus compiler-related and/or typo fixes to CKVFIO.C from Tarjei Jensen:
 * 102 18-Aug-93 ttj Minor updates in zsattr() and do_label_recv() mainly to
 *                   quieten the compiler (which had every reason to complain).
(Installed 10 Oct 93).

Added keypad period (".") to the list of numeric keypad keys that return
different scan codes from their main keypad equivalents -- final step in
making the PC numeric keypad able to work like the DEC one.  From Kai Uwe
Rommel.  ckotio.c 5A(105) 11 Oct 93.

Corrections to X.25 functions from <[e-mail]>: A PAD
command (either a SET, READ, or SETANDREAD) without any parameters specified
in the command means "all supported parameters."  For the SET commands, it is
a "reset to initial values."  As passed to qbitpkt(), n is the number of data
bytes in the packet, which starts at s.  The control byte has already been
stripped off.  When passed to either setpad() or readpad(), n is the number of
parameters in the command/query.  ckcnet.c 5A(020) 13 Oct 93.

A change from Alex Dupuy <[e-mail]>: if C-Kermit is compiled with
-DNOCMDL (no command-line arguments) and -DNOICP (no interactive command
parser), then instead of building a program that just exits, build one that
goes into server mode with all default settings.  Alex suggests that we can
also rip out all local-mode supporting code in this case (since there is no
way to SET LINE any more) to make a truly minimal remote-only version.
Settings can still be accomplished via REMOTE SET commands.  C-Kermit built
on a PC with 'make dellsys5r4m "KFLAGS=-DNOCMDL -DNOICP"' weighs in at 90K.
ckcmai.c 5A(190) 14 Oct 93.

Changed the protocol module to issue "KERMIT READY TO blah..." messages
consistently, and to make them appear (in remote mode) no matter whether
the file transfer command was given interactively or from a command file
or macro.  ckcpro.w 5A(056) 14 Oct 93.

Changes for BSDI from John T. Kohl <[e-mail]>.  ckcdeb.h,
ckutio.c.  Aside from adjusting BSDI-isms, John (partially) fixed a big
problem with tthflow() that had previously been hacked around in the Linux
case, by passing the appropriate terminal info structure to tthflow() as an
argument.  I removed the special case for Linux.  Unfortunately, the hardware
flow control status is not kept in the terminal info on some systems,
e.g. SVR4, SunOS.  And since John started things off in this direction, I made
further attempts to clean up the hardware flow control situtation in the UNIX
version, adding a new parameter to tthflow() to specify whether hardware f/c
is to be turned on (1) or off (0), and then replacing various chunks of
misplaced system-specific code by calls to tthflow().  Compiles OK on SunOS
4.1.3, 4.4BSD, SVR4, needs testing.  ckutio.c 5A(113) 20 Oct 93.

John also added a new command, which he called PUSHREM and which I decided to
call REDIRECT, which is like RUN, but with stdin and stdout redirected to the
communication device (serial or network connection).  For UNIX only, needs
forks, dup(), wait(), and needs <sys/wait.h> to define WIFEXITED() and
WEXITSTATUS().  This commmand is compiled in only if the symbol CK_REDIR is
defined at compile time, and then only when NOPUSH is not defined.  Fixed up,
adapted to, and tested on SunOS 4.1.3, SVR4, Linux.  Could not get it working
on the NeXT or AIX, which have no definition for WEXITSTATUS().  If you try to
build the program with CK_REDIR defined and the required macros are not
available, C-Kermit will print a message "?Sorry, can't execute this command -
missing pieces" if you try to use the REDIRECT command.  Also, I added a new
token, "<" (leftbracket), as a synonym for REDIRECT (like "!" is a synonym for
RUN), and, when CK_REDIR is defined, made "red" and "redi" valid non-unique
abbreviations for REDIAL.  ckuusr.h, ckuusr.c 5A(104), ckutio.c, ckuus[25].c.
25 Oct 93.

Added "designer banners" for Linux and BSDI BSD/386.  ckuver.h.  20 Oct 93.

After testing of new RTS/CTS code by Rick Sladkey, made some more changes,
unified Linux and BSDI RTS/CTS code, reorganized, consolidated, cleaned up,
documented.  ckutio.c 5A(114) 21 Oct 93.

Fixes from Chuck Goodhart <[e-mail]>:
 . The SCRIPT command can sometimes cause TELNET negotiations to be ignored.
 . The SCRIPT command is slowed by unbuffered output to the console
   and the session log.
 . The SCRIPT command does not filter out carriage returns when
   SET SESSION-LOG TEXT is set.
 . While SET SESSION-LOG TEXT, TELNET negotiations should not be logged.
 . The INPUT command is also slowed by unbuffered output to the console and
   the session log.
 . ttinc(timo) should ignore the timeout when, if MYREAD buffered
   input is being used, a character is known to be available.  This
   saves two calls to signal() and two calls to alarm(), dramatically
   improving the performance of the INPUT command.
