        !             2: 
        !             3: general (many modules affected):
        !             4: . Change "set send packet-length" to override Send-Init value.
        !             5: . Change still more global character variables from int or char to CHAR.
        !             6: . Fix 4.1BSD and C/70 support (Charles Brooks), 2.9 support (Herm Fischer).
        !             7: 
        !             8: ckcfns.c:
        !             9: . Server always executes generic (but not host) commands in text mode.
        !            10: . Change calling convention for getchx() to allow better reporting of eof.
        !            11:   Some earlier changes had apparently broken PDP-11 support for binary
        !            12:   files because of sign extension...
        !            13: . Again, several hours after initial announcement of 4C(057) found that above
        !            14:   change had busted things for 68000s (again) because of still more int/char
        !            15:   conversion problems.  Changed 'next' from int to char and moved its file
        !            16:   begin/end function to a new flag variable, 'first'.  Hopefully, not too many
        !            17:   copies got out; those that did are dated 29 July; the version with this fix
        !            18:   is dated 31 July.  Sigh...
        !            19: 
        !            20: ckuusr.c:
        !            21: . Fix timing statistics to work for 16-bit machines too (Dan).
        !            22: . Change calls to execl() to terminate with "(char *)0", not "0".
        !            23: 
        !            24: ckufio.c:

        !            26: 
        !            27: ckutio.c:
        !            28: . Herm fixed it up so all the changes in previous edits that broke his
        !            29:   modem control code are now more compatible with it.  Also, myread() -- the
        !            30:   nonblocking equivalent of read() -- was fixed to report errors better.
        !            31: 
        !            32: ckudia.c:
        !            33: . Many changes from Herm & Dan, mostly relating to modem control and resetting
        !            34:   alarms to get the dialing-with-no-carrier-to-connected-with-carrier
        !            35:   transition working again.
        !            36: 
        !            37: 
        !            38: C-KERMIT FOR UNIX, CHANGES FROM 4C(055) TO 4C(056), 11 JUL 85:
        !            39: 
        !            40: ckcpro.w:
        !            41: . Make new ssfile state, to allow for display of data in ack to file header.
        !            42: . If data comes in ack to file header, log to transaction file.
        !            43: . Put local filename in data field of ack to F packet.
        !            44: . Add calls to new rtimer(), gtimer() to allow transactions to be timed.

        !            46:   Previously, only "czseen" would do it, but not cxseen.
        !            47: . Upon receipt of Z packet, send Ack AFTER closing file rather than before.
        !            48:   If file can't be closed, send Error packet instead of Ack.
        !            49: . Upon receipt of error packet while receiving file, discard file.
        !            50: . Upon receipt of unexpected packet type, send Error, not Nak.
        !            51: 
        !            52: ckcfns.c:
        !            53: . Change clsof() to accept an argument specifying whether to discard.
        !            54: . Change clsof() to keep incomplete file regardless of arg if keep != 0.

        !            56: . Change name of getch() to getchx() to avoid conflict with libraries.
        !            57: . Fix Yet Another Problem with 8th-bit Quoting Negotation.  The bug was that
        !            58:   if other side said 'N' we would treat 'N' as quoting prefix rather than "NO"
        !            59:   (but only if parity was set to other than none).
        !            60: . Remove input buffer flush from sfile() (why was it ever there???).
        !            61: . Change seof() to accept an argument to put in the Z-packet data field.
        !            62: . Add transaction timing statistics to reof(),reot() for transaction log.

        !            67:   read rather than whole buffer (required changing inlin()'s return code).
        !            68: . Allow rpack to skip over "blank lines" without failing; this was preventing
        !            69:   file transfer with some systems that always sent CRLF before transmitting
        !            70:   anything (e.g. UCLA's MVS/TSO VTAM).
        !            71: . Don't flush input buffer at end of rpack(), because if the packet that we
        !            72:   just read is a repeat or an echo, the one we want might be queued up after
        !            73:   it.  Instead, flush in input() only after the desired packet arrives.
        !            74: . Allow user to type ^A^C^C to interrupt rpack and exit cleanly from program.
        !            75:

        !            79: . Add elapsed time and effective baud rate display to "statistics" command.
        !            80: . Fix "show parameters", had send/receive end-of-packet reversed.
        !            81: . Make modem-type lookup in "show" a little cleaner.
        !            82: . Fix "echo" to interpret \ooo escapes in its argument.
        !            83: 
        !            84: ckuus2.c:
        !            85: . Add "help set incomplete".

        !            92: . Fix "set send/receive padding/pad-character" -- they had variables reversed.
        !            93: 
        !            94: ckufio.c:
        !            95: . For Pro/Venix V1, make MAXWILD and SSPACE even smaller, so malloc() still
        !            96:   has some space left to allocate...
        !            97: . Change zclose() to return -1 if file could not be closed.
        !            98: 
        !            99: ckutio.c:
        !           100: . Use Sys III/V nonblocking read() technique also for 4.xBSD -- improves

        !           102: . Add rtimer() and gtimer() functions for resetting/getting elapsed time.
        !           103: . Don't return failure from tthang() if line wasn't open.
        !           104: . Print warning message if tthang() or ttunlk() fail.
        !           105: . In ttclos(), relinquish exclusive access.
        !           106: . Change some #ifdefs so they depend on features, like FIONREAD, rather than
        !           107:   system, like BSD4.  This allows collapsing a lot of redundant code.
        !           108:

        !           189: . In cmifi(), make y long rather than int.  This was making some 16-bit

        !           213:   local status when stdin redirected.  If not Sys III/V and stdin redirected,
        !           214:   assume local, rather than remote, so that "set speed" and other local-mode

        !           217: . Make new ANYBSD symbol to select 4.1, 4.2, and 2.9.  In some cases, all 3
        !           218:   work the same, in others, 2.9 and 4.2 are the same, 4.1 special.
        !           219: 
        !           220: ckuus*.c:
        !           221: . In command line invocation, base local/remote determination on CTTNAM.
        !           222: . In "set line" only ask ttopen() to set local/remote if not default tty.
        !           223: . Ignore SIGQUIT and SIGINT signals while inferior shell active in XXSHE:.
        !           224:   Previously, both Kermit and the inferior shell would catch them.
        !           225: . In XYLINE: call ttopen() with a temp, x, rather than "local", then only
        !           226:   set local if x was set.
        !           227: . Change message "status report..." to "status report:" to avoid dot confusion.

        !           230: C-KERMIT FOR UNIX, CHANGES FROM VERSION 4.2(030) TO 4C(050), 30 May 85:
        !           231: 
        !           232: All files except ckwart.* have been renamed according to a consistent
        !           233: convention, see ckaaaa.hlp for an explanation.
        !           234: 
        !           235: Copyright notices added to every module, so we can't be enjoined from
        !           236: distributing our own program if we give the right to other organizations,
        !           237: like Berkeley, to distribute it.
        !           238: 
        !           239: ckwart.c
        !           240: 
        !           241: . Move the #define in the txt1 string to not start on a new line.
        !           242: . Fix the comments printed by wart so they can't be construed as comments
        !           243:   by the compiler that compiles wart.
        !           244: . Include formfeed among the skipped-over whitespace characters.
        !           245: . Add wart version information. 
        !           246: 
        !           247: ckcdeb.h (formerly ckdebu.h):
        !           248: 
        !           249: Forget about typedefing LONG to be unsigned long -- it causes too many
        !           250: problems for PDP-11 C compilers, etc.  Just let LONG be long.
        !           251: 
        !           252: If symbols DEBUG and TLOG not defined (e.g. in Makefile), then define
        !           253: null macros to replace calls to the debug() and tlog() functions, to save
        !           254: space and execution time.  Program is too big for Macintosh with these
        !           255: functions compiled in.
        !           256: 
        !           257: Establish a symbol NLCHAR.  If this symbol is defined, then text (ascii)
        !           258: files are stored with a single character (such as lf or cr) terminating
        !           259: each line, and this character is the value of NLCHAR.  If not defined,
        !           260: then the system uses CRLF.  When NLCHAR is defined, C-Kermit maps between
        !           261: that character and CRLF.
        !           262: 
        !           263: ckcfns.c, ckcfn2.c (formerly ckfns.c, ckfns2.c):
        !           264: 
        !           265: . change all calls to screen() to new form.
        !           266: . fix bug in sfile() that sometimes prevented literal names from working.
        !           267: . don't translate send-as names in sfile, always use them literally.
        !           268: . change input() to always resend() after getting a NAK.
        !           269: . change getpkt to clear leftovers when starting new file (next = -1),
        !           270:   so that filenames in F pkt wouldn't have garbage after previous file
        !           271:   was interrupted.
        !           272: . Change call to zchin() to use new calling convention so bytes with
        !           273:   hi bit on won't be confused with eof on some systems.
        !           274: . Reset czseen in seof, not in clsif, so that remote ^X while C-Kermit
        !           275:   sending will result in correct Z packet with D in data.
        !           276: . In resend(), don't send any packet if packet buffer is empty.
        !           277: . Un-hardwire getch() from Unix newline text file convention.
        !           278: . Fix bug that sometimes resulted in contents of R or X packet
        !           279:   having first character doubled.
        !           280: . Fix bug in getpkt that prevented leftovers from being transmitted
        !           281:   after end of file.
        !           282: . Have tinit() clear c[xz]seen and filnam to prevent bad things happening
        !           283:   after interruption or emergency protocol exit.
        !           284: . Have syscmd() return 0 if called with null string.  This allows single
        !           285:   process systems like the Macintosh to act as servers, even if they can't do
        !           286:   commands like remote directory.
        !           287: . Send out initial nak when doing receive, so that there will be something
        !           288:   in the packet buffer to resend.
        !           289: . Check for failure return code from zchout, to catch disk full errors, etc.
        !           290: . When server getting input from a system function, call zopeni() on new
        !           291:   ZSYSFN channel, rather than circumventing zopeni() by calling zopen().
        !           292: . Clean up inlin() a little, use maxt vs MAXTRY consistently. 
        !           293: . Change rpack,spack,rpar,spar,etc to use the new, separated send/receive
        !           294:   packet parameters (padding,timeout,eol,soh,etc).
        !           295: 
        !           296: ckcker.h (formerly ckermi.h):

        !           298: . Removed #include <stdio.h> and <ctype.h> from ckermi.h.  Macintosh does not
        !           299:   need all that... (thanks, Bill)
        !           300: . Remove include of ckdebu.h (now ckcdeb.h).
        !           301: . Add defs for LF and NUL.
        !           302: . Add def for new ZSYSFN file i/o channel.

        !           305: 
        !           306: . Add "a" state to cancel any transaction.
        !           307: . Remove entries for input='N', since this is now handled by input().
        !           308: . Fix "a" state to not cause "OK" message when files closed.
        !           309: 
        !           310: ckucmd.c (formerly ckcmd.c) Unix Command Package:
        !           311: 
        !           312: . Set global cmerrp (error prefix) to be same as prompt, but with '>' stripped.
        !           313: . Allow interactive command continuation using trailing '\'.
        !           314: . Change "*bp++ == NUL;" in getwd() to simply "bp++;".

        !           316: . In ckucmd.h, #define getchar specially for VMS and Aegis.
        !           317: . In cmfld, return(0) from filling out default when ESC typed; this prevents
        !           318:   "log trans <ESC>transact.log <ESC>transact.log <ESC>transact.log ..."
        !           319: . In cmtxt, preserve pointers & counts across calls in case of reparse.

        !           375: 
        !           376: . Changed calling convention for ttopen() to allow it to set the "local"
        !           377:   variable, since ttopen can call the system to figure out whether a given

        !           383:   target).  Should fix PC/IX tthang() problem.
        !           384:

        !           392: . continuation lines now allowed in commands if line ends with "\".
        !           393: . make "dir" command arg default to ".", not "*", to prevent recursive listing.
        !           394: . make "!" command with no args do system("$SHELL").

        !           399:   broken by send-as change above, few people saw it).
        !           400: . Put 'log debug' command in #ifdef DEBUG
        !           401: . Put 'log transaction' command in #ifdef TLOG

        !           403:   'transaction.log', which is too long for all but 4.2bsd Unixes.
        !           404: . Use symbols for exit() & doexit() return codes, not hardwired 0 and 1.
        !           405: . Use symbol for name of init file.
        !           406: . Put Unix-specific messages in #ifdef's

        !           410: . In ckuus3, change "turnch == y" to "turnch = y"; this bug prevented

        !           418:   status report doesn't show all 0's on systems where ints and longs
        !           419:   are different length (%ld was already used in the other screen functions).
