KERMIT工具 这在办公室下载不了,很多人都没有载不到.

  following was done.

  All code (regardless of module) which outputs telnet commands is placed
  into a mutex region to ensure that competing output threads do not result
  in interleaving their output.  This could happen for instance when the
  forward-x thread is forwarding data and the user changes the window size
  or sends an AYT or BREAK.  Next the buffer used for input and output
  processing were identical.  This means that output data could be treated
  as input or vice versa.  Ugh....

  I also spent some more time cleaning up setlin().  Mostly reorganizing the
  code into single if (...) blocks so that breaking it up will be easier.

ckctel.c ckuus7.c, 4 Jan 2002.

Updated internal copyright notices.  All modules, 5 Jan 2002.

From Jeff:
  More of same, plus new makefile target and changes from Spike Gronim
  for freebsd44+srp+openssl.
ckcdeb.h ckcnet.c ckctel.c ckuus7.c ck_ssl.c makefile, 5 Jan 2002.

Some minor updates and fixes to SSH and SET SSH help text.
ckuus2.c, 6 Jan 2002.

Added SET RGB-COLORS for GUI.  ckuusr.[ch], ckuus3.c, 6 Jan 2002.

From Jeff: More Telnet changes, Debug semaphores for K95, etc: ckcdeb.h,
ckuusr.h, ckuus[r35x].c, ckctel.[ch], ckuath.c, 7 Jan 2002.

Added --xpos:n --ypos:n, SET GUI WINDOW POSITION x y, and changed SET
RGB-COLORS to SET GUI RGBCOLOR.  Action needs to be filled in (in setguiwin()
in ckuus3.c), and gui_xpos and gui_ypos need to be defined in cko???.c.
ckuusr.h, ckuus[r3y].c, 7 Jan 2002.

Added --fontname:name --fontsize:name (and facename as synonym for fontname).
ckuusr.h, ckuus[7y].c, 7 Jan 2002.

Moved GUI (not OS/2) SET TERM FONT code in ckuus7.c to its own routine,
setguifont(), in ckuus3.c, and made GUI SET TERM FONT call this routine,
and also made SET GUI FONT call the same routine.  ckuus[37].c, 7 Jan 2002.

Added --termtype:, --height:, --width:, --user:.  Also added symbols for
--telnet:, --ssh:, --ftp:, --[remote-]charset, and --password:, but didn't
fill them in.  --password: is probably not a good idea (but we allow it for
FTP); the others involve a lot of code-shuffling and reconciliation, which
I'll try to do when I get a chance (especially the connection ones, which
can be done as part of the setlin() restructuring).  ckuusr.h, ckuusy.c,
8 Jan 2002.

Also I tried commenting out the #ifndef KUI..#endif's around SET TERMINAL
CHARACTER-SET (easier said than done because a crucial #endif was mislabeled).
Let's see if it compiles & works...  ckuus7.c, 8 Jan 2002

Added FTP [ OPEN ] /NOINIT, meaning don't send REST, STRU, and MODE commands
upon making an FTP connection.  This allows connection to servers that close
the connection (or worse) when given these commands (e.g. Linux 2.4 TUX 2.0
FTP server).  ckcftp.c, 8 Jan 2002.

Looked at adding caller ID support for the ANSWER command:

 . SET ANSWER CALLER-ID { ON, OFF }
 . SET ANSWER RINGS <number>
 . \v(callid_xxx) xxx = { date, time, name, nmbr, mesg }
 . CKD_CID modem capability
 . Set CKD_CID for modems that have it.
 . A quick survey shows:
   - USR V.90:      No (but Jeff says some USRs have it).
   - V.250:         No
   - Lucent Venus:  No
   - USR:           #CID=1 (the ones that have it -- X2?)
   - Diamond Supra: #CID=1
   - Rockwell 56K:  #CID=1
   - PCTEL:         #CID=1
   - Zoltrix:       +VCID=1
   - Conexant:      +VCID=1
 . Since there are different commands to enable caller ID reporting,
   we need a new field in struct MDMINF.
 . SHOW MODEM and SHOW DIAL would need updating.
 . etc etc...

This is all way too much for now so I just did the setting of the \v(callid_*)
variables.  These are reset at the beginning of an ANSWER command, and then
set by the ANSWER command if they come in; thus they persist from the time
they are collected until another ANSWER command is given.  To take advantage
of autoanswer, the user has to enable it in the modem (all the modems I found
that support it have it disabled by default), and also has to set the number
of rings to at least 2.  This can be done with (depending on the modem):

  set modem command autoanswer on ATS0=2#CID=1\{13}
  set modem command autoanswer on ATS0=2+VCID=1\{13}

and undone with:

  set modem command autoanswer on ATS0=1#CID=0\{13}
  set modem command autoanswer on ATS0=1+VCID=0\{13}

The variables can be accessed only after the call is answered.  Therefore the
only way to refuse a call is to answer it, inspect the variables, and then
hang it up if desired.  Future Kermit releases can do this more nicely (as
sketched out above.)  Also while I was in the dialing code, I added result
code VCON (= VOICE), used by several of the newer modems.  These changes are
untested.  The SET ANSWER command is written but commented out.  ckuusr.h,
ckcker.h, ckuus[r3].c, ckudia.c, 8 Jan 2002.

From Jeff: fixes to --termtype:, --height:, --width:, --user:, and filling in
of --rcharset:, which required extracting code from settrm() into a separate
parse-method-independent remote character-set setting routine.  ckuus[7y].c,
8 Jan 2002.

From Jeff: More work on TERMINAL CHARACTER-SET code reorganization, and
reinstatement of SET TERMINAL CHARACTER-SET in K95G.  Also, fix char/CHAR
warnings in Telnet module.  ckuus7.c, ckctel.c, 9 Jan 2002.

Made SET TERM CHARACTER-SET visible for all builds, including K95G, and filled
in HELP text for it.  ckuus[27].c, 9 Jan 2002.

Added help text for new extended options.  ckuusy.c, 9 Jan 2002.

Commented out the return(-2) statement at the end of xgnbyte() to make the
"Statement not reached" errors go away, after checking to make sure that there
was no path that could fall through to the end.  I'm 99.99% sure there isn't,
but that doesn't mean that some compilers might not still complain.  ckcfns.c,
9 Jan 2002.

From Jeff: fix typo in the K95 extended-option help text; add more
semaphores to network i/o.  ckuusy.c, ckcnet.c, 10 Jan 2002.

Undid ansiisms in set{lcl,rem}charset() declarations.  ckuus7.c, 10 Jan 2002.

Removed a duplicated clause from the install target.  makefile, 10 Jan 2002.

From Jeff: more semaphores.  ckcnet.c, 11 Jan 2002.

Moved references to tmpusrid and tmpstring out of NOSPL #ifdefs -- they can
be used with NOSPL.  setlin(): ckuus7.c, 13 Jan 2002.

Made a dummy dologend() routine outside of #ifndef NOICP, so we don't have
to enclose every reference to dologend in #ifdefs.  (I had added a bunch of
calls to dologend() throughout the code to handle automatic LOCUS switching.)
ckuus3.c, 13 Jan 2002.

Moved "extern int nettype" outside of NOICP #ifdefs in ckuus4.c for NOICP
builds.  13 Jan 2002.

Moved a misplaced #ifdef in the VERSION command.  ckuusr.c, 13 Jan 2002.

Did 81 different feature-selection builds on Linux (RH 7.0), all OK after the
changes listed above for today.  13 Jan 2002.

Added prototypes for set{rem,lcl}charset().  ckcxla.h, 13 Jan 2002.

Added ckcxla.h to dependencies for ckuusy.c.  ckvker.com, 13 Jan 2002.

Made a correction to the HELP SET LOCUS text and supplied a missing comma
for HELP REMOTE.  ckuus2.c, 13 Jan 2002.

Built OK on HP-UX 11.11 (K&R and ANSI), Solaris 8 (cc), Solaris 2.5.1 (gcc),
SunOS 4.1.3 (cc and gcc), VMS 7.1 (DEC C, net and nonet), Unixware 7.1.1,
Tru64 4.0G, HP-UX 10.20 (K&R), AIX 4.3.3, FreeBSD 2.2.8, Slackware 8.0, IRIX
6.5.13f, IRIX 5.3 (??? Can't tell -- the computer ran out of swap space -- but
it was OK a few days ago), VMS 5.5-2 (VAX C, UCX + nonet)...  HP-UX 9.05, ...

Some corrections to comments in HP targets from PeterE.  makefile, 14 Jan 2002.

Corrections to prototypes for set{rem,lcl}charset() (VOID, not void) from Jeff.
ckcxla.h, 14 Jan 2002.

Builds, cont'd...  SINIX 5.42, Red Hat Linux 5.2 on i386, SuSE 7.0 on S/390, 
Red Hat 7.1 on IA64, QNX 4.25, HP-UX 5.21/WinTCP, ..., 

Dell Coleman <[e-mail]> noticed that in AIX, the COPY command always
says "Source and destination are the same file" when the destination file
doesn't exist.  This is because in AIX, realpath() fails with ENOENT (errno
2).  The zfnqfp() code already accounts for this, but evidently not well
enough.  So I did what I should have done long ago.  zfnqfp() was originally
accomplished with do-it-yourself code.  Later I added support for realpath(),
and partitioned the routine into mutually exclusive compile-time sections:
#ifdef CKREALPATH realpath()... #else do-it-yourself... #endif.  But if
realpath() failed, there was no recourse to the do-it-yourself code.  Today I
replaced the #else with the #endif, so the do-it-yourself part is always
included and is executed if the realpath() call fails.  Built and tested on
AIX 4.3.3 and Solaris 2.5.1, as well as on Linux with and without the
realpath() code included.  zfnqfp(): ckufio.c, 16 Jan 2002.

Separated K95 and C-Kermit test version numbers, so C-Kermit can be RC.02
while K95 is Beta.01.  ckcmai.c, 16 Jan 2002.

Inhibited 0-length writes by conol() and conoll(), since they cause big
trouble with the AIX 4.3.3 pty driver, e.g. when you have an SSH connection
into AIX and run C-Kermit there.  ckutio.c, 16 Jan 2002.

Suppressed "Switching LOCUS..." messages from FTP client when it was invoked
from the command line.  ckcfns.c, 17 Jan 2002.

Dave Sneddon noticed that FOPEN /APPEND gets "?Write access denied" in VMS
if the file exists.  This is apparently because VMS zchko() does the wrong
thing.  Commenting out the call zchko() in the VMS case gets past this but
then the appended part of the file has different attributes than the orignal
part, e.g.:

  abc  <- original line (horizontal, normal)
  d    <- appended line (vertical)
  e
  f

VMS fopen() takes an optional 4th argument: a series of RMS keyword=value
pairs.  Kermit doesn't give any.  Experimentation shows that appending to
a Stream_LF works fine.  That'll be a restriction for now, until somebody
sends in code to get the RMS attributes of the original file and feed them
to fopen().  Also need code to fix VMS zhcko() to say whether it's OK to
append to a file.  ckuus7.c, 17 Jan 2002.

Somebody suggested I could get a working Kermit for Neutrino 2+ by doing the
QNX6 build on Neutrino itself.  I verified that this can't be done -- at least
not by me -- since Netutrino 2+ doesn't have a compiler, and we already know
the version cross-built for it on QNX4 doesn't work.  17 Jan 2002.

From Jeff: SET SSH GSSAPI KEY-EXCHANGE { ON, OFF } parsing, SHOW SSH.
ckuus3.c, 18 Jan 2002.

PeterE suggested that SET ESCAPE allow 8-bit escape characters because of the
difficulty in entering Ctrl-\ on European keyboards and the hardship (e.g. to
EMACS and VI users) of sacrificing another C0 control character.  Like
everything these days, this turns out to be rather a bigger deal than it would
seem.  The SET ESCAPE parser calls setcc(), which accepts control characters
in various formats (literal, ^X notation, or numbers), and gives an error
return if the value is not 0-31 or 127.  This is changed easily enough to also
allow numbers between 128 and 255.  But who else calls setcc()?  The commands
for setting Kermit packet start and end characters.  No big deal, this gives
people a bit more flexibility in case they need it, but it won't be
documented.  setcc(): ckuus7.c, 18 Jan 2002.

Since code to display the escape character is scattered all over the place,
and some of it indexes into an array based on the character value (which would
now dump core if the escape character was > 128), I put the code in one place,
a new shoesc() routine in ckuusx.c (which needs to be outside #ifndef NOICP,
since the CONNECT modules use it even in command-line only builds).  Also
discovered that this code was indexing into the nm[] array with tt_escape to
get "enabled" or "disabled", which is no longer appropriate, so fixed this
too.  ckuusr.h, ckuus[5x].c, 18 Jan 2002.

Made SHOW ESCAPE, SHOW TERM, and the various CONNECT modules call shoesc(),
and updated HELP SET ESC.  ckuus[25].c, ckucns.c, ck[cuvd9]con.c, 18 Jan 2002.

After all that, it occurred to me that this is a really bad idea for K95,
with all the confusion about Console code pages, OEM code pages, Windows
code pages, and Unicode.  But I tried "echo \161" at the K95 prompt and got
the expected 8-bit character in both the Console version and the GUI, so
maybe it's OK after all.

Removed the automatic IKSD login code from setlin() since it complicates
interactive anonymous login.  ckuus7.c, 20 Jan 2002.

An #ifdef clause from Matthew Clarke to avoid "redeclaration of free" error
when building a curses version of C-Kermit for AIX 2.2.1 on RT PC.  ckuusx.c,
22 Jan 2002.

Took care of one detail I omitted when adding the 8-bit escape character:
not stripping the 8th bit before comparing the keyboard char with the escape
char.  ck[uv]con.c, ckucns.c, 24 Jan 2002.

Started to go through Jeff's changes of the last week but he had run trim -t
on them, which untabifies, so the diffs were huge.  Retabifying Jeff's files
only makes matters worse.  So instead of comparing each old and new source
file in EMACS windows with M-X Compare-Windows like I usually do (which can't
be told to ignore whitespace), I had to work from the diff -c -b listings.
In ascending order of size of diffs:

ckcker.h: Add I_AM_SSHSUB definition.
ckuusr.h: XXLINK and VN_PERSONAL, etc, definitions.
ckuusy.c: Support for "I Am SSHSUB" invocation.
ckuus5.c: Support for new K95 directory structure.
