C-KERMIT FOR UNIX, CHANGES FROM 4C(052) TO 4C(053), 21 JUNE 85: ckcfn2.c: . Change dopar() to be of type CHAR. . Fix dopar() to calculate odd parity correctly. ckucon.c, ckuscr.c: . Add "extern CHAR dopar();" declarations. C-KERMIT FOR UNIX, CHANGES FROM 4C(050) TO 4C(052), 18 JUNE 85: ckcfns.c: . Repair rpar() and spar() handling of 8th bit prefix negotiation. . In sinit(), when sending from stdin, allow "-a name" to work. . In rcvfil(), guard against receiving a null F packet. ckcmai.c: . Change hlptxt[] to contain less than 256 characters (for Xenix) ckcpro.c: . In proto() call ttopen() with a temp, x, rather than "local", then only set local if x was set. ckucmd.c: . In cmifi(), make y long rather than int. This was making 16-bit machines erroneously report that files longer than 32K could not be found. ckuker.mak (makefile): . Change symbol 3BX to ATT3BX (has to start with letter) . Remove line continuations in the middle of strings . Add entry for sys3nid (System III/V on PDP-11 with no I&D space) ckufio.c: . Add appropriate #ifdef for TOWER1 in zkself() . Add 2.9bsd identification string ckutio.c: . Move definition of CTTNAM from here to ckcdeb.h, so it can be shared. . In initrawq() (for V7 only) read the proc table again after fork(). . Change symbol 3BX to ATT3BX. . Get rid of the (void) casts in strxxx() invocations -- the proliferation of conditionals was getting ridiculous, and it was only to please lint. . In conbin() for Sys III/V, open terminal in 7-bit, parity-enabled mode rather than 8-bit, no-parity mode (some sites actually use parity). . In conint(), trap and ignore QUIT signal, trap SIGHUP and handle like SIGINT. This prevents lock files from being left behind after hangup or quit. . In connoi(), turn off traps for SIGQUIT, SIGHUP. . In ttopen(), add Sys III/V code using ctermid() to better determine remote/ local status when stdin redirected. If not Sys III/V and stdin redirected, assume local, rather than remote, so that "set speed" and other local-mode only commands will work. . Add 2.9bsd identification string . Make new ANYBSD symbol to select 4.1, 4.2, and 2.9. In some cases, all 3 work the same, in others, 2.9 and 4.2 are the same, 4.1 special. ckuus*.c: . In command line invocation, base local/remote determination on CTTNAM. . In "set line" only ask ttopen() to set local/remote if not default tty. . Ignore SIGQUIT and SIGINT signals while inferior shell active in XXSHE:. Previously, both Kermit and the inferior shell would catch them. . In XYLINE: call ttopen() with a temp, x, rather than "local", then only set local if x was set. . Change message "status report..." to "status report:" to avoid dot confusion. C-KERMIT FOR UNIX, CHANGES FROM VERSION 4.2(030) TO 4C(050), 30 May 85: All files except ckwart.* have been renamed according to a consistent convention, see ckaaaa.hlp for an explanation. Copyright notices added to every module, so we can't be enjoined from distributing our own program if we give the right to other organizations, like Berkeley, to distribute it. ckwart.c . Move the #define in the txt1 string to not start on a new line. . Fix the comments printed by wart so they can't be construed as comments by the compiler that compiles wart. . Include formfeed among the skipped-over whitespace characters. . Add wart version information. ckcdeb.h (formerly ckdebu.h): Forget about typedefing LONG to be unsigned long -- it causes too many problems for PDP-11 C compilers, etc. Just let LONG be long. If symbols DEBUG and TLOG not defined (e.g. in Makefile), then define null macros to replace calls to the debug() and tlog() functions, to save space and execution time. Program is too big for Macintosh with these functions compiled in. Establish a symbol NLCHAR. If this symbol is defined, then text (ascii) files are stored with a single character (such as lf or cr) terminating each line, and this character is the value of NLCHAR. If not defined, then the system uses CRLF. When NLCHAR is defined, C-Kermit maps between that character and CRLF. ckcfns.c, ckcfn2.c (formerly ckfns.c, ckfns2.c): . change all calls to screen() to new form. . fix bug in sfile() that sometimes prevented literal names from working. . don't translate send-as names in sfile, always use them literally. . change input() to always resend() after getting a NAK. . change getpkt to clear leftovers when starting new file (next = -1), so that filenames in F pkt wouldn't have garbage after previous file was interrupted. . Change call to zchin() to use new calling convention so bytes with hi bit on won't be confused with eof on some systems. . Reset czseen in seof, not in clsif, so that remote ^X while C-Kermit sending will result in correct Z packet with D in data. . In resend(), don't send any packet if packet buffer is empty. . Un-hardwire getch() from Unix newline text file convention. . Fix bug that sometimes resulted in contents of R or X packet having first character doubled. . Fix bug in getpkt that prevented leftovers from being transmitted after end of file. . Have tinit() clear c[xz]seen and filnam to prevent bad things happening after interruption or emergency protocol exit. . Have syscmd() return 0 if called with null string. This allows single process systems like the Macintosh to act as servers, even if they can't do commands like remote directory. . Send out initial nak when doing receive, so that there will be something in the packet buffer to resend. . Check for failure return code from zchout, to catch disk full errors, etc. . When server getting input from a system function, call zopeni() on new ZSYSFN channel, rather than circumventing zopeni() by calling zopen(). . Clean up inlin() a little, use maxt vs MAXTRY consistently. . Change rpack,spack,rpar,spar,etc to use the new, separated send/receive packet parameters (padding,timeout,eol,soh,etc). ckcker.h (formerly ckermi.h): . Removed #include and from ckermi.h. Macintosh does not need all that... (thanks, Bill) . Remove include of ckdebu.h (now ckcdeb.h). . Add defs for LF and NUL. . Add def for new ZSYSFN file i/o channel. ckcpro.w (formerly ckprot.w) Protocol Module: . Add "a" state to cancel any transaction. . Remove entries for input='N', since this is now handled by input(). . Fix "a" state to not cause "OK" message when files closed. ckucmd.c (formerly ckcmd.c) Unix Command Package: . Set global cmerrp (error prefix) to be same as prompt, but with '>' stripped. . Allow interactive command continuation using trailing '\'. . Change "*bp++ == NUL;" in getwd() to simply "bp++;". . Test for CR as well as NL for line termination (for Apollo Aegis). . In ckucmd.h, #define getchar specially for VMS and Aegis. . In cmfld, return(0) from filling out default when ESC typed; this prevents "log trans transact.log transact.log transact.log ..." . In cmtxt, preserve pointers & counts across calls in case of reparse. . In getwd, return -1, NOT -2, if ^U (line kill) is typed. ckucon.c (formerly ckconu.c) Connect module: . When writing to session log, make some minimal attempt to recover from disk full or other i/o errors (just turn off logging flag). . Add baud and parity info to status display. ckudia.c (formerly ckdial.c) Dial command: . Support added for Racal-Vadic, Cermetek, Penril, General Datacomm. . Use msleep() for higher precision timing. ckufio.c (formerly ckzunx.c, and before that ckzbsd.c): Started from Charles Brooks's 4.2 ckzunx.c, which is the original C-Kermit release 4.2 version, to which he added 4.1bsd support. . Fixed zltor() to only count dots after the last '/'. . Declared malloc as "char *malloc()". . Change fprintf(fp[n],s) to fputs(s, fp[n]) in zsout & zsoutl. . Added zkself() function to log self out, for use by server "bye". . Changed calling convention for zchin() to allow 68000's etc to return EOF. . Make zopeno() chown the file to self, in case program set[ug]id'd. . Changed znewn() to try not to contruct a name that is too long. . Merge in Gregg Wonderly's v7 support. . Make various changes to v7 support to fit proc table stuff to other systems. . (023) Changed zopeni(), when called with new ZSYSFN channel number, to invoke zxcmd() to start a fork and get its fd; also changed zclose() and chkfn() accordingly. . (024) In zchki(), allowed 0 as well as S_IFREG as S_IFMT value for ordinary file; Sys V stat() can return either of these values for an ordinary file. Also, insert missing #else in zkself(). . (025) declare zchki() to be of type 'long', so that it can return valid file sizes for big files. Also fix internal variables that hold size to also be long. (Same change to ckvfio.c.) Also, change ckcfns.c and ckucmd.c to declare 'long zchki();'. ckutio.c (formerly ckxunx.c and ckxbsd.c): Started from Charles Brooks's 4.2 ckxunx.c, which is the original C-Kermit release 4.2 version, to which he added 4.1bsd support. . Added the following for Pro/Venix Version 1: - Filled in msleep() using alarm(-clockticks). - Filled in conchk() and ttchk() using TIOCQCNT. - Changed default tty name (dftty) to be "/dev/com1.dout". - Added line locking via /usr/spool/uucp/LCK..devname and TIOCEXCL. . Changed local variable c from int to CHAR in ttinl(). . Let CEB's code to hangup line upon close in 4.1bsd also work for 4.2bsd. . Removed flock() from ttopen(), call ttlock() before trying to open tty. . Corrected some places where alarms & signals were not turned off. . Changed calling convention for ttopen() to allow it to set the "local" variable, since ttopen can call the system to figure out whether a given device is the job's controlling tty. Also had to change all modules that call ttopen() to pass this variable by reference instead of by value. . In ttopen, copy ttname string into a static ttnmsv string global to ckutio module, rather than just copying the pointer (which is pointing at a moving target). Should fix PC/IX tthang() problem. . Add support for AT&T 3B-series under 3BX conditional; initially, it just follows UXIII conditional, but uses special uucp lock file name. ckuusr.c, ckuus2.c, ckuus3.c (formerly ckuser.c, ckusr2.c, ckusr3.c): . all occurrences of printf(s) replaced by printf("%s",s) or puts(s). . shortening of remaining long strings. . continuation lines now allowed in commands if line ends with "\". . make "dir" command arg default to ".", not "*", to prevent recursive listing. . make "!" command with no args do system("$SHELL"). . removed redundant definitions of ncmd, nrmt, nprm. . totally redefined and rewrote screen() function. . Change send-as to use cmtxt, not cmfld; remove cmcfm. . Fix send command to wait for confirmation after wild filespec (this was broken by send-as change above, few people saw it). . Put 'log debug' command in #ifdef DEBUG . Put 'log transaction' command in #ifdef TLOG . Use 'transact.log' as default name for transaction log, rather than 'transaction.log', which is too long for all but 4.2bsd Unixes. . Use symbols for exit() & doexit() return codes, not hardwired 0 and 1. . Use symbol for name of init file. . Put Unix-specific messages in #ifdef's . In 'set line', put speed back to -1 if not local. . Change "*xargv++;" in cmdlin() to simply "xargv++;". . Change all "if (x = (cmcfm()) < 0)" to "if ((x = cmcfm()) < 0)". . In ckuus3, change "turnch == y" to "turnch = y"; this bug prevented "set handshake" from working. . Add code in shopar() to look up and display modem type correctly. . Change "set line" code to have ttopen() figure out local/remote mode. . Fix "set line" not to erroneously set ttname if it ttopen fails. . In remote cwd parsing, accept CR as well as NL as password terminator. . In local directory command, use DIRCMD rather than "ls -l ". . In screen() function SCR_QE, print long argument with %ld so the ^A status report doesn't show all 0's on systems where ints and longs are different length (%ld was already used in the other screen functions). . Fix multiline 'get' parsing to allow editing (required fixes to ckucmd.c). . Add conditionals for init file name for various systems. . Phase out the following set commands: set end-of-packet, set start-of-packet, set timeout, set padding & pad-ch. Replace by set send (each of these) and set receive (each of these), to allow inbound & outbound packet parameters to be set separately. . Put new set send/receive params in show command display. . Add version info for ckudia and ckuscr to 'sho ver'. . Add init file name to 'sho param'. . Replace system("pwd") in XXCWD code with system(PWDCMD), defined in ckufio.
