writes, particularly in the "estimated time left" slot, so I added 3 lines
of code to screenc() so Kermit could optimize this itself.
ckuusx.c, 21 Nov 93.

From Kai Uwe Rommel, 21 Nov 93 (begin quote):

I have fixed the problems. Included I send a few diffs and a new ckotio.c,
because I took the opportunity for a few cleanups in this module.

I have also made changes to allow compilation with IBM's TCP/IP 2.0, which has
a 32-bit socket interface.  Unfortunately, this has the implication, that now
*two* DLL's are required, SO32DLL.DLL and TCP32DLL.DLL.  Also, the executable
doesn't run with TCP/IP 1.2.1 any longer.  So, we should make the distributed
32-bit executable for TCP/IP 1.2.1 and it also runs with TCP/IP 2.0.  I made
changes only to allow someone to recompile C-Kermit if he has only TCP/IP
2.0.  To fully support it, we will have to wait until I finally find the time
to restructure the TCP/IP support.

I have, BTW, dropped the IBMSELECT code, because it is not needed, both TCP/IP
1.2.1 and 2.0 support the BSD select() call and that is more portable.

Another problem: It is currently not possible to check for the return code of
programs run via zshcmd().  In addition, the exit code was not returned
correctly from zsyscmd() in the aegis and OS/2 cases.  I have somewhat quick-
fixed zshcmd() for the OS/2 case to allow the "IF FAIL" command to work.  The
UNIX branch has to be fixed too.  However, that only allows to check if the
return code is not zero.  Sometimes it would be convenient to determine the
exact exit code of the program.  How about adding a variable \v(exitcode)
which holds the return code of the last program run via zshcmd() or zsyscmd()?

My current wish list of things I would like to do looks like:
- Fix timed keyboard input with an additional thread instead of alarm()
- Restructure TCP/IP code to support multiple vendors with one executable
- Allow remote operation over serial lines and TELNET connections
- Add Tektronix emulation

Built 16- and 32-bit OS/2 versions OK, 21 Nov 93; put cko190.zip up for
testing on net.  All reactions so far are positive.

Another INPUT command speedup: Rather than always doing 1-second timed reads,
time each read for the amount of time left in given timeout interval.  This
reduces the number of system calls considerably, and still works fine --
succeeds when it should succeed, fails when it should fail, terminates
correctly under both extremes: no characters arriving at all; a steady stream
of characters arriving.  ckuus4.c 21 Nov 93.

Revisited old problem of UNIX and VMS CONNECT showing a couple garbage
characters upon first accessing a second or subsequent connection.  It was
just a matter of having the CONNECT module reset its i/o buffer pointers
whenever it knew it had a new connection, or that the current connection had
terminated because of an i/o error.  CKVCON.C (VMS) 5A(031), ckucon.c (UNIX)
5A(058), 23 Nov 93.

When transferring a file with packets longer than about 2300, debug() calls
would fail because the text to be logged was longer than the debug-record
buffer.  This made it tough to track down certain kinds of errors related to
long packets.  I changed the debug code to grow the buffer as necessary,
dynamically.  ckuusx.c, 24 Nov 93.

Moved closing of debug log to just before _exit() is called, so now we can log
the actions of ttres(), ttclos(), etc.  Reorganized UNIX ttclos() to not do a
lot of silly things to the command terminal, especially if it was using stdin
(file descriptor 0) to communicate with it.  ckutio.c, 24 Nov 93.

Added new WRITE-LINE (synonym: WRITELN) command.  Just like WRITE, except
it writes its argument string in the form of a line or record, appropriate to
the underlying operating system.  This lets scripts create output files
in a system-independent fashion.  ckuusr.c 5A(113), 24 Nov 93.

Change ttclos() in ckutio.c for UNIX to unset the TIOCSINUSE flag for the
device, since this bit had been set for it in ttopen().  I'm not sure if this
fixes any problem, but it shouldn't hurt.  Also, changed sysinit() to call
priv_ini() before doing anything else at all.  Apparently some UNIX versions
(386BSD, etc) won't allow a set[gu]id program to open /dev/tty to get the
terminal modes, etc, so this makes Kermit's effective UID be the user's real
UID before any attempt is made to get terminal modes, etc.  ckutio.c 5A(117)
24 Nov 93.

Removed "#define WAIT_T pid_t" from ckcdeb.h (within #ifdef POSIX).
Apparently, this is just completely wrong -- nowhere is the argument to wait()
a pid_t; it's always either an int or else a struct of some kind.  According
"Portable C Software", it's always safe to call wait() with an (int *).
ckcdeb.h 24 Nov 93.

Changed lockfile for 386BSD from /var/spool/uucp to /var/spool/lock --
suggested by many people.  makefile.

Changed ckhost(), the routine that gets the local host name, to call
gethostbyname() in 386BSD, rather than utsname().  Suggested by Nick Sayer
<[e-mail]>, who says 386BSD (a.k.a. Jolix 0.1+pk0.2.4) didn't have
utsname().  ckuusx.c.

Chased down a report that SET DIAL INIT-STRING didn't work when invoked from
a macro.  As far as I can tell, it works fine.  However, SHOW DIAL did not
report your DIAL INIT-STRING or PREFIX if you had not previously SET MODEM to
something, which could be misleading.  ckudia.c 5A(051) 24 Nov 93.

The file attributes structure, zsattr, defined in ckcdeb.h, contained a member
called passwd.  But some C compilers can't deal with structure members having
the same names as other identifiers.  This killed C-Kermit compilation under
Altos Xenix 3.0.  Reported by Ken George <[e-mail]>.  ck*fio.c, 24 Nov 93.

Fixed BSEND and TSEND macros in standard CKERMIT.INI file; they would mess
up if given wildcards.

Fixed SET HOST and TELNET commands to automatically SET CONTROL PREFIX 255
for TCP/IP connections.  This omission pointed out by Bill Glass.  ckuus7.c,
25 Nov 93.

INPUT commands, when executed from VMS C-Kermit in remote mode for reading
material from the console terminal (e.g. for checking terminal answerback
sequence), were not working right because the VMS version of coninc() did not
check to see if it timed out in certain cases and returned a character value
like 0 or 127 rather than -1 in these cases.  Fixed in coninc(), CKVTIO.C
2.0-064 25 Nov 93.

VMS C-Kermit session logs were being written in Stream_LF format, but still
contained carriage returns, which made them look funny when viewed in VMS
editors (little arrows showed up at the end of each line).  This was fixed by
opening the session log with "rfm=stm" (new) as well as "ctx=stm".  Suggested
by Jason Seaman <[e-mail]>, Whitaker College, MIT.  CKVFIO.C
2.0-105, 25 Nov 93.

Executing a series of file transfer commands from a command file or macro took
an inordinate amount of time because of long, annoying pauses between each
command.  It seems there were some gratuitous sleep(1)'s and sleep(2)'s in the
protocol module.  These were to allow "nonblocking" mode changes to take place
between command and protocol mode.  These sleeps really had no business in the
protocol module, and should be placed -- if necessary! -- in the appropriate
system-dependent modules.  Removing them makes multiple local-mode transfers
(send this, send that, send another, ...) go just as fast as a single wildcard
transfer.  For remote-mode transfers: same speedup, but you have to remember
to put SET DELAY 0 in your command file!  ckcpro.w 5A(057), ckutio.c 5A(118),
25 Nov 93.

Built today's version on SunOS 4.1.3, NeXTSTEP 3.0, Dell System V R4,
OpenVMS/VAX, OpenVMS/AXP, Linux 0.99.13, RS/6000 AIX 3.1, DEC OSF/1-AXP.

A couple minor adjustments for FreeBSD to yesterday's code from Scott Mace
<[e-mail]>: declaration of sys_errlist[] in ckcfn3.c, SET
SPEED keyword list in ckuus3.c, vanity banner for FreeBSD.  While futzing with
the SET SPEED list yet again, I took the opportunity to redesign how it works.
Kermit-specific symbols are now defined (or undefined) in ckcdeb.h for the
uncommon speeds, and these can be augmented or overriden from the CC command
line using BPS_xxxx or NOB_xxxx symbols.  Also, added 57600 and 115200 for
Linux, and added an as-yet-unused entry for 230400 bps.  Documentation on
speed configuration added to ckccfg.doc.  26 Nov 93.

Added SET CONSOLE as an invisible synonym for SET COMMAND, as the word CONSOLE
is bit more intuitive, and in preparation for possibly adding other console-
related items, like SPEED, PARITY, FLOW, ...  ckuusr.c 5A(114) 26 Nov 93.

About 6-8 weeks ago, Paul Placeway sent in a new set of source for Macintosh
Kermit, in which several bugs were fixed in the Mac-specific (ckm*.*) modules,
and which had been adapted for compilation under Think C as well as MPW C.
These have now been adapted to C-Kermit edit 190, and I made several other
changes too: added a fix to doactive() from Ed Huff <[e-mail]>,
apparently overlooked by Paul (?); I filled in the zhome() and zgtdir()
functions (code from Steven Woolgar <[e-mail]>); enabled the CD
and PWD commands as well as the corresponding functions and variables.  Some
changes to ckcdeb.h, ckuus5.c, ckuusr.c, ckcfns.c.  Compiles under MPW C 3.2
just fine, seems to run OK too, except CD command still pops up a bunch of
windows on the screen saying "Writing to the console in applications is NOT
supported!".  And zhome() always seems to return the null string.  And
zgtdir() always seems to return the name of the disk, but not the current
folder... (see code for these in ckmfio.c.)  26 Nov 93.

Added makefile entry for FreeBSD from Scott Mace <[e-mail]>.
29 Nov 93.

Added SET PRINTER and SHOW PRINTER commands for OS/2 C-Kermit.  ckuusr.h,
ckuusr.c, ckuus2.c, ckuus3.c, ckuus5.c.  30 Nov 93.

ID swapping needed for access() in the BSDI version: -DSW_ACC_ID added to
the bsdi makefile entry.  From John Kohl.  1 Dec 93.

A fix from Kai Uwe Rommel for an OS/2 C-Kermit bug: if Kermit was left in
CONNECT mode, the OS/2 system could not be shut down.  ckotio.c 5A(110)
1 Dec 93.

Added SET { FILE, TERMINAL } CHARACTER-SET HP-ROMAN8, to support Hewlett
Packard's proprietary Latin-1-like 8-bit character set.  The translation used
is the one provided by HP (e.g. via iconv); it is not invertible.  Also, fixed
incorrect translation from DGI to Latin-2.  ckuxla.h, ckuxla.c 5A(021),
1 Dec 93.

Fixed TRANSLATE command to work right when one (or both) of the character-sets
is Latin-2 or CP852.  ckuus4.c, 1 Dec 93.

Changed terminal emulator in OS/2 C-Kermit to not display transparent-print
material on the screen, since this is how a real VT102 works.
ckocon.c 5A(106) 1 Dec 93.

Consolidated and rearranged some Mac-specific definitions and declarations:
ckcdeb.h, ckmusr.c, ckmtio.c, ckuus5.c, ckuus6.c.  The need for this was
pointed out by Joe Bearly <[e-mail]>.  1 Dec 93.

Fixed sdata() to make a special case for the Atari ST when looking to see
whether to interrupt the D-packet-sending loop, because the ST version of
ttchk() never returns a value > 1.  ckcfn2.c 5A(049) 1 Dec 93.

Changed the packet-mode interruption defaults from 2 Ctrl-C's to 3 Ctrl-C's.
This prevents protocol breakouts when users SET CONTROL UNPREFIX 3 or 131,
because 3 Ctrl-C's in a row will be encoded with a repeat count.  This change
might be a little disconcerting to users, but when they type two and nothing
happens, they will almost certainly type a third.  ckcmai.c, 2 Dec 93.

Added a new compile-time symbol: NDGPWNAM.  If you define this, e.g. in
CFLAGS or KFLAGS, it skips the forward declaration of getpwnam() in ckufio.c,
presumably because it was already declared in <pwd.h>, and avoid "conflicting
types for getpwnam" errors, e.g. from GCC 2.5.6.  ckufio.c 5A(077) 5 Dec 77.

The 32-bit version of OS/2 C-Kermit, when in server mode, failed to redirect
the output of REMOTE DIRECTORY, REMOTE TYPE, and similar commands (which work
by running a copy of CMD.COM via popen()), to the Kermit client.  Rather, the
output would appear on the server's screen.  This was caused by a bug in the
IBM C++ PDK Beta compiler which I have been using.  I upgraded to IBM C++ Set
2.0, and the problem went away.  8 Dec 93.

When Kai Uwe dropped the OS/2 C-Kermit IBM-style select() in favor of the BSD
version, he forgot to update ckotcp.c and ckotcp.def, so OS/2 C-Kermit would
no longer run on systems where IBM TCP/IP was not installed, because of a
dynamic linking error at startup time caused by _bsdselect missing from the
dummy DLL.  Kai Uwe to the rescue.  8 Dec 93.

Bo Kullmar noticed that SET TRANSFER CANCELLATION 3 3 does not quite make it
safe to SET CONTROL UNPREFIX 3.  This is because the code in ttinl() to check
for cancellation ignored the parity bit, so (for example) \x03\x83\x03 could
still kill a transfer.  I changed ttinl() to ignore the parity bit only if
PARITY was not NONE; this should be nearly 100% safe now that all C-Kermit
programs capable of remote-mode operation also do automatic parity detection.
Also, packet-mode interruption should occur only when C-Kermit is in remote
mode, but ttinl() was letting it happen in local mode too, so I changed it.
Also, I removed cancellation code from two C-Kermit programs that included it,
but that could never be in remote mode: Mac Kermit and Atari ST Kermit.
