MUSIC Kermit 4.2.x "Beware File" - Known Bugs, Problems, Limitations. As of: 12:12pm Friday, 1993 Jan 22 This file contains (A) instructions for applying Kermit updates, (B) a list of unresolved problems, (C) a list of problems with work-arounds or optional fixes, and (D) a list of resolved problems. Bug reports should be sent to Pierre Goyette <PIERRE@MCGILL1>. NOTE: entries will sometimes be entered under (D) even though the needed updates have not been released in IKMKER.UPD. Please check the date of the UPD file to see if it has been changed before requesting a new copy. Kermit-370 now carries an "edit" number in addition to the version and release numbers. The three numbers together are printed out in the assembly listing and displayed by Kermit at startup time. Be sure to include all three numbers (e.g., 4.2.3) along with any error reports. A) Update instructions ................................................. Many updates have been received since Kermit-370 4.1 was released. All updates prior to 90/4/14 have been removed from IKMKER.UPD and applied to the sources in the process of creating 4.2. If your source does not include the line defining &KVRSN to be 4.2, you should obtain an all-new source distribution from Columbia. Any updates created later than your source should be applied before you make the executable module. In general, updates received at Columbia will not be included in the source files in the MUSIC Kermit distribution until and unless "major" bugs are uncovered, and then all accumulated updates will be applied at once. The description of each problem and a pointer to its solution will always be included in IKMKER.BWR (the present file), but the updates themselves are to be found in IKMKER.UPD. The procedure to update your copy of MUSIC Kermit is as follows: 1) Obtain the latest version of IKMKER.UPD, which contains all the updates, each preceded by a separator beginning "./ * :READ" and giving the update's name. Please note that some modes of file transport have a side effect of either doubling or removing any periods in the first column -- if your copy of IKMKER.UPD has records beginning with "/", then all instances of "/" in column 1 should be changed to "./". Similarly, any instances of ".." in columns 1-2 should be changed to just ".". A related problem can affect the sources by leaving a blank in column 80. That can happen via the loss of a "." in column 1 (in which case the sequence number will be shifted into columns 72-79) or via automated efforts to preserve the "." (in which case the sequence number will be truncated). The repair consists of inserting the missing "." in column 1 or "0" in column 80. 2) Determine the date of your sources. If you received them from a secondary supplier, you will need to examine the source code to determine the most recent update applied. Just sort the combined source by columns 67-71: the last line will be labelled with the last-applied update. Although the current official sources for the generic and MUSIC-specific parts of Kermit were released at the same time, it may be necessary in the future to determine the dates separately for the two types of source code (IKM*.ASM vs. IK0*.ASM). 3) If your sources predate all the updates in IKMKER.UPD, i.e., if they are "pure" Columbia 4.2, go on to step 4. Otherwise, go through the list of updates at the beginning of IKMKER.UPD and note which ones are already included in (i.e., are older than) your sources. MUSIC- specific ones are marked as such, in case your generic and MUSIC parts have different dates. Disable each such redundant update by deleting the update from the update file. 4) Follow the installation guide to assemble the GUPI Program (Generic Update Program) and then assemble and test the new Kermit source. ------------------------------------------------------------------------ B) Unresolved problems ................................................. ---------------- 89/1/15 ----------------------------------------------- MUSIC-Kermit cannot execute arbitrary host commands. ---------------- 89/1/20 ----------------------------------------------- Now that Kermit-370 supports multiple-filespec SEND, it is possible for a single SEND subcommand to specify overlapping wildcard filespecs. Only the CMS variant keeps track and makes sure that it doesn't send the same file twice within one send invocation. The others, including MUSIC Kermit-370, may send the same file again, and it is left to the user to prevent filename-collision problems on the receiving end. ---------------- 90/5/8 ------------------------------------------------ With a few exceptions, CONTROLLER will be set automatically when Kermit is invoked. See file IK0AAA.HLP in the Kermit distribution for a list of front ends that have been reported to allow Kermit file transfers and another list of reported failures. ---------------- 92/4/22 ----------------------------------------------- Kermit-MUSIC does not yet support file names longer than 22 characters in all, including the code designation. The new directory-style names, in particular, are not allowed. ------------------------------------------------------------------------ C) Problems with workarounds or optional fixes ......................... ---------------- 89/2/27 ----------------------------------------------- The code for detecting the difference between SERIES1- and GRAPHICS-type terminal controllers may cause peculiar error messages at session startup, particularly if you try to run Kermit on an IBM 3270-type terminal. For example, you might see a PROG470 or PROG729 error. Normally, Kermit can recover from these error conditions, but some configurations and/or versions of VTAM may hang the terminal session instead. If you cannot get Kermit-MUSIC to start up successfully, you might want to bypass the code (especially if you don't have any GRAPHICS-type terminals). The code is governed by a set of switches which can be tailored to your needs: STCQBIT EQU X'01' WSF Query is always allowed STCQNS1 EQU X'02' WSF Q implies *not* SERIES1 STCS1 EQU X'04' Always assume SERIES1 STCNOS1 EQU X'08' Always assume *not* SERIES1 STCNORD EQU X'10' Asynch READ MOD is forbidden Since there is apparently no way for a program running under MUSIC to determine whether a WSF Query is allowed, Kermit-MUSIC must assume that it is. Therefore, the standard flag value is STCQBIT; if you wish to force the code to select SERIES1, you should change that to STCS1, as in the following: ./ * SC9131X - Customize controller type selection ./ R 01151200 $ 1151200 100 11/21/91 00:16:50 &CONOPTS SETC 'STCS1' SETCON options @SC9131X Alternatively, if you have *only* GRAPHICS-type controllers, you could change it to STCNOS1 (or STCNOS1+STCQBIT if you also have 3174 AEA controllers). Note: prior to version 4.2.2 of Kermit-MUSIC, the SERIES1 option was "wired" in for all fullscreen sessions. See the entry of 91/8/19 in part D for further notes. ---------------- 90/7/5 ------------------------------------------------ Kermit-370 now honors the file type specification (binary or text) given by a sending Kermit in an Attribute packet. Old procedures for sending binary files may therefore not work properly anymore. To return to the old mode of operation, issue the subcommand SET ATTR TYPE OFF. To live with the new mode, be sure to issue the SET FILE TYPE to both sending and receiving Kermits (to be safe). ---------------- 90/7/30 ----------------------------------------------- When the file type is TEXT and the recfm is F, Kermit-370 strips off trailing blanks from each record before sending a file. In order to keep trailing blanks in a downloaded file, you can convert it to RECFM V before sending it. ---------------- 90/8/22 ----------------------------------------------- If, for some reason, the other Kermit insists on pretending ASCII bytes all have the 8th bit set, Kermit-370 will not detect the intended CRLF separators between lines. The result of uploading from such a Kermit is a (text) file with only one record. If the other Kermit cannot be fixed, the following update will make Kermit-370 treat ASCII 8D and 8A the same as 0D and 0A, as long as the ATOE table does so. ./ * SC90151 - Forgive 7-bit ASCII files with 8th bit on ./ I 02490500 $ 2490700 200 08/03/90 16:06:46 ISW78 DC X'7F' Start with 7-bit ASCII @SC90151 ./ I 02713500 $ 2713700 200 08/03/90 16:06:46 SW78 DS X'7F' Switch for 7-bit/8-bit ASCII @SC90151 ./ I 03436000 $ 3436500 500 06/01/90 13:24:03 KCALL TBLCRLF Note current treatment @SC90151 ./ I 03442000 $ 3442500 500 06/01/90 13:24:03 KCALL TBLCRLF Note current treatment @SC90151 ./ I 04318000 $ 4318500 500 06/01/90 13:24:03 KCALL TBLCRLF Reset 7-bit/8-bit mask for CRLF @SC90151 ./ I 04386000 $ 4386080 80 06/01/90 13:24:03 * * Entry: nothing special @SC90151 * Exit: SW78 set up correctly @SC90151 TBLCRLF ENTER ALT @SC90151 MVI SW78,255 Assume 8-bit codes @SC90151 CLC ATOE+ALF(1),ATOE+ALF+128 @SC90151 BNE RTRN0 @SC90151 CLC ATOE+CR(1),ATOE+CR+128 @SC90151 BNE RTRN0 @SC90151 MVI SW78,127 No, 7-bit codes @SC90151 B RTRN0 @SC90151 ./ I 08048000 $ 8048400 400 NC CUR,SW78 If 7-bit ASCII, ignore 8th bit @SC90151 ---------------- 91/11/21 ---------------------------------------------- In order to change the default Kanji encoding from IBM-style to another, add one of the following updates. ./ * SC9132X - Change Kanji default ./ R 01411560 $ 1411560 10 11/21/91 @SC9132X &KNJDEF SETC 'HITACHI' Default Kanji @SC9132X ./ * SC9132X - Change Kanji default ./ R 01411560 $ 1411560 10 11/21/91 @SC9132X &KNJDEF SETC 'FUJITSU' Default Kanji @SC9132X ---------------- 92/4/10 ----------------------------------------------- The minimum size of strings to be subjected to run-length encoding may need to be changed to two to make the new FULLSCREEN mode work on certain protocol converters, such as the MICOM 7400, which convert three successive blanks into cursor motion commands (or even two!). The following update accomplishes that. ./ * SC92101 - Encode multiple blanks ./ I 07929000 $ 7929050 50 04/10/92 17:35:12 CLI 0(8),ABL Is it a blank? @SC92101 BNE ENCRP1 No, use normal criterion @SC92101 C 14,F2 @SC92101 BNL ENCRP2 Always encode multiple blanks @SC92101 ENCRP1 DS 0H @SC92101 ./ I 07929600 $ 7929800 200 04/10/92 17:35:12 ENCRP2 DS 0H @SC92101 ---------------- 92/4/6 ------------------------------------------------ The time of day associated with a disk file was introduced in MUSIC/SP in version 2.1. For prior releases, the following update is needed to avoid undefined symbols. ./ * SC92127 - Compatibility with pre-2.1 MUSIC ./ D 01034500 ./ R 01044500 $ 1044500 200 MFXIDT DS AL4 Dummy time of day (pre-2.1 MUSIC) @SC92127 ./ D 05423500 ---------------- 92/6/10 ----------------------------------------------- Kermit-370 now appends an extra message to the normal protocol-mode greetings, provided DELAY is at least 2. The extra message is of the form "KERMIT READY TO SEND..." (or RECEIVE or SERVE). ./ * SC92161 - Add universal send/rec/serve greetings ./ R 08634000 08638000 $ 8634000 600 06/10/92 11:35:48 LA 6,80 @SC92161 INTINIT1 CR 4,6 @SC92161 BNH INTINIT2 Just one line left @SC92161 WTEXT (3),(6) Write out one line @SC92161 AR 3,6 Point to next line @SC92161 SR 4,6 Adjust length remaining @SC92161 B INTINIT1 @SC92161 ./ R 08663000 08665000 $ 8663000 1000 06/10/92 11:35:48 INTCCWSR DC A(INTMSGSR,INTPRL+80+80+80) @SC92161 INTCCWSN DC A(INTMSGSN,INTPRL+80+80+80) @SC92161 INTCCWRC DC A(INTMSGRC,INTPRL+80+80+80) @SC92161 ./ I 08676000 $ 8676500 500 06/10/92 11:35:48 DC CL80'KERMIT READY TO RECEIVE...' @SC92161 ./ I 08680000 $ 8680500 500 06/10/92 11:35:48 DC CL80'KERMIT READY TO SEND...' @SC92161 ./ I 08684000 $ 8684500 500 06/10/92 11:35:48 DC CL80'KERMIT READY TO SERVE...' @SC92161 ---------------- 92/10/18 ---------------------------------------------- When Kanji characters are first selected, the default for the single- byte character set is CP290 (hard-coded in Kermit-370). That can be changed, however: ./ * SC92252 - Make CP281 the default SBCS with KANJI ./ R 04448600 $ 4448600 100 10/18/91 20:52:19 TBVJP DC CL(LALF)'CP281',CL(LALF)'CP500',CL(LALF)'CP290' @SC92252 ---------------- 92/10/27 ---------------------------------------------- Kermit-MUSIC needs to line up the columns with the heading for the LIBRARY subcommand. The following update corrects this. ./ * SC92301 - Correct columns for directory listing (MUSIC) ./ R 06269000 $ 6269000 100 10/27/92 21:21:35 S 5,F5 @SC92301 ------------------------------------------------------------------------ D) Resolved problems ................................................... ---------------- 90/5/8 ------------------------------------------------ A commonly reported "problem" is that Kermit-MUSIC objects to a send packet size greater than 94, and users wonder how to turn on long-packet protocol for downloads. The answer is that the the maximum packet size in Kermit protocol is always dictated by the receiving Kermit -- ALWAYS. NOTHING YOU CAN SAY TO A SENDING KERMIT WILL EVER MAKE IT SEND PACKETS LONGER THAN THE RECEIVING KERMIT ASKS FOR. Conversely, Kermit-MUSIC will always use packets as long as possible unless frequent transmission errors indicate a noisy communication line. The only purpose for the send packet-size parameter in Kermit-MUSIC is to set the default, in case the receiving Kermit is badly crippled (in which case, long packets are entirely out of the question anyway), or to control "raw" downloads (those without Kermit protocol and parameter negotiation). ---------------- 90/5/8 ------------------------------------------------ Kermit-370 is often faced with a communication front end that treats an XOFF from the other end as an end-of-line. Thus, in server mode, it may receive "packets" consisting of XON XOFF or just XOFF when the micro issues flow control for purely precautionary reasons. Such packets are now ignored, rather than treated as invalid server commands. The fix: SC90106. ---------------- 90/5/14 ----------------------------------------------- Kermit-370 is now careful not to attempt to send packets longer than the (system-specific) hardware maximum. The fix: SC90134. ---------------- 90/5/30 ----------------------------------------------- Kermit-370 now accepts PACKET-LENGTH as an alias for PACKET-SIZE in SET SEND or SET RECEIVE. The fix: SC90150. ---------------- 90/6/10 ----------------------------------------------- Kermit-370 now supports transfers in LATIN2 and LATIN3 and file storage in CP870, CP880, and CP905. In addition, L1, L2, and L3 are recognized as aliases for the three LATIN sets, and two-character abbreviations are accepted for the other transfer sets as well. The new sets add support for Afrikaans, Albanian, Catalan, Croatian, Czech, Esperanto, Galician, Hungarian, Maltese, Polish, Romanian, Slovak, Slovene, and Turkish. The fix: SC90152. ---------------- 90/6/22 ----------------------------------------------- Kermit-370 supports file transfers through the IBM 3174 AEA with level 2 microcode in configuration B. The support is restricted to terminal types defined in the 3174 to have ASCII Graphics capability. That capability is available by default only for VT241 and Tektronix 4205 terminals, but user-defined terminal types are also possible. Also, the Graphics capability is allowed only for lines defined without associated Host Addressible Printers. Kermit-370 now automatically detects the B2 AEA and sets CONTROLLER accordingly (to AEA if Graphics is allowed, to NONE if not). However, if the 3174 is owned by VTAM, and the connection is made with a logmode that forbids the Read Partition Query (such as M2SDLCNQ), Kermit cannot detect the AEA and will default to CONTROLLER GRAPHICS (and, incidentally, cannot transfer files even with CONTROLLER set to AEA by hand). M2SDLCQ is known to allow correct operation, but other logmodes have not been tested. Since the 3174 supports full 8-bit communication, it may be useful to configure the ports for 8-bit data and to set both SEND and RECEIVE PARITY to NONE in Kermit-370. The fix: SC90173. Note: B2 microcode became available from IBM in May 1990. B3 followed soon afterward, and it supports file transfer the same way as B2. ---------------- 90/6/28 ----------------------------------------------- Kermit-370 now gives correct status reports after an XTYPE, rather than retaining the error code, if any, from a previous transfer. Also, XTYPE now supports the full, extended syntax of SEND. The fix: SC90179. ---------------- 90/7/30 ----------------------------------------------- Kermit-370 now uses the FILE COLLISION settings for all files in a group rather than just the first. The fix: SC90211. ---------------- 90/8/14 ----------------------------------------------- When DEBUG is set to I/O, Kermit-MUSIC now includes the hex dump of the FSIO block and data buffer in KERMIT.LOG for each full screen I/O operation, and errors are flagged. The fix: SC90222. ---------------- 90/8/27 ----------------------------------------------- Kermit-370 now has three new subcommands: REMOTE MAIL, REMOTE PRINT, and REMOTE SUBMIT. They transmit a file (or group of files via wild cards) tagged for mailing, printing, and submitting as job, respectively. The syntax is: REMOTE MAIL/PRINT/SUBMIT filespec options The options are passed to the receiving Kermit and must be in a format it will understand. The fix: SC90239. ---------------- 90/9/7 ------------------------------------------------ Kermit-370 now has a TRANSPARENT transfer character set, which applies a null translation to all incoming and outgoing files. The fix: SC90250. ---------------- 90/9/27 ----------------------------------------------- Kermit-370 failed to use control-quoting on 8-bit analogs of ordinary control characters if 8th-bit quoting was turned off. The fix: SC90270. ---------------- 90/9/27 ----------------------------------------------- Kermit-370 now suppresses echoing in protocol mode on LU1 3770-type front ends by sending Inhibit/Enable Presentation controls (EBCDIC x'24' and x'14'). These characters should have no effect on "old-fashioned" linemode equipment. The fix: 2L90270. ---------------- 90/9/28 ----------------------------------------------- Some corrections to the Cyrillic translation tables. The fix: SC90271. ---------------- 90/10/4 ----------------------------------------------- Kermit-370 now keeps separate limits on packet buffer sizes for linemode and fullscreen devices and no longer assumes that the latter is always bigger. The fix: SC90277. ---------------- 90/10/5 ----------------------------------------------- Kermit-370 now has a SET TTABLE KP option which enables a full 8-bit translation table based on Hollerith codes. The fix: SC90278. ---------------- 90/10/12 ---------------------------------------------- Kermit-370 now allows testing with a packet character that is not a control character without requiring that the test character be avoided in the data. The fix: SC90285. ---------------- 90/10/16 ---------------------------------------------- Kermit-370 now leaves server mode if packet I/O errors recur. The fix: SC90289. ---------------- 90/10/19 ---------------------------------------------- The extraneous B packet after an XTYPE (introduced in 4.2.1) is now avoided. The fix: SC90292. ---------------- 90/12/4 ----------------------------------------------- V-binary (or D-binary) file transfers trashed the last 2 (or 5) bytes of any record of 65535 bytes. The fix: SC90338. ---------------- 90/12/5 ----------------------------------------------- Kermit-370 now has a VERSION subcommand, which displays the version number and date. The fix: SC90339. ---------------- 91/1/8 ------------------------------------------------ Kermit-370 now has a facility for taking snapshot dumps of selected storage blocks during execution and another for tracing events. See SET DEBUG in the User's Guide for more details. The fixes: SC91008 and LM91008. ---------------- 91/1/17 ----------------------------------------------- Kermit-370 now generates a more informative error message if an attempt to open a file for output fails. The fix: SC91017. ---------------- 91/2/1 ------------------------------------------------ Kermit-370 now interprets the terminal input more liberally when looking for possible STOP commands in protocol mode. If the word STOP appears in either upper- or lower-case EBCDIC, rather than ASCII, it is accepted as a valid STOP. This can be useful in recovering from an attempt to start a tranfer through a device that has no transparent mode. The fix: SC91032. ---------------- 91/3/5 ------------------------------------------------ Kermit-370 now displays any extra explanatory error message (such as those for I/O errors) along with the basic message upon completing a subcommand. The fix: SC91064. ---------------- 91/3/8 ------------------------------------------------ Support for lower-case Roman letters has been added to CP290 (Katakana). Some corrections have been made to the LATIN2-to-CP870 table. The fix: SC91067. ---------------- 91/4/4 ------------------------------------------------ Kermit-370 now processes any incoming Date attribute for validity, even though no variant currently uses it. The fix: SC91094. ---------------- 91/4/9 ------------------------------------------------ Kermit-370 now supports an "End-of-attributes" attribute. There is no current application, but its existence should facilitate negotiation of file attributes when it becomes generally supported by other Kermits as well. If another Kermit objects to the new attribute (not likely), you can suppress it by typing SET ATT END OFF. The fix: SC91109. ---------------- 91/4/26 ----------------------------------------------- Kermit-370 now supports a "CC" option along with the line range for sending files. This option specifies that the file has carriage control in column 1 and that it should be converted to ASCII control characters. For example: SEND filespec<_CC> (the underscore is the option delimiter and indicates here that no line range is given). The fixes: SC91116 and SC91224. ---------------- 91/5/1 ------------------------------------------------ Kermit-MUSIC now allows multiple subcommands to be entered on the initial command line, separated by the Kermit delimiter, which must be defined in one of the initialization files. All such subcommands will now be executed in turn before Kermit quits and returns. The fix: SC91121. ---------------- 91/6/14 ----------------------------------------------- Kermit-370 now stops attempting to cancel a received file via the "YX" method after ten tries have been ignored by the sender. At that point, it issues an E-packet saying "Transfer cancelled". The fix: SC91165. ---------------- 91/6/21 ----------------------------------------------- Kermit-370 now records the time of starting each file transfer in the transaction log. Also, the error message for a cancellation includes the reason (if known), both in the transaction log and in error packets. Further, there is a new DEBUG option TIME that causes a time tag to be inserted into each I/O debug log record. The fix: SC91172. ---------------- 91/6/29 ----------------------------------------------- Kermit-370 now supports 8th-bit quoting for the XECHO subcommand, using the same prefix character as in Kermit protocol. The quoting can, thus, be turned off. The fix: SC91180. ---------------- 91/7/10 ----------------------------------------------- Kermit-370 now avoids a long-standing "hidden" bug: transfers no longer fail if DEBUG is set to RAW while long packets are in use. The fix: SC91191. ---------------- 91/7/17 ----------------------------------------------- Kermit-370 now mentions REMOTE PRINT in the remote help display. The fix: SC91198. ---------------- 91/8/19 ----------------------------------------------- Kermit-370 is now at level 4.2.2: SC91231. At this level, Kermit is no longer compatible with MUSIC/SP releases before 2.2. However, applying the workaround (described 89/2/27 above) will restore compatibility back to MUSIC/SP 1.2, as with previous versions of Kermit. ---------------- 91/9/4 ------------------------------------------------ Kermit-370 no longer halts a transfer upon seeing a data packet with no data. The fix: SC91247. ---------------- 91/9/13 ----------------------------------------------- Kermit-370 now allows the STOP command on PCI and certain other protocol converters that did not previously support it. The fix: SC91256. ---------------- 91/9/20 ----------------------------------------------- Kermit-370 no longer gives a spurious reason for a cancellation issued by user intervention on the micro. The fix: SC91263. ---------------- 91/10/2 ----------------------------------------------- Kermit-370 supports locking shift protocol (helps to compress certain files with many 8-bit bytes). The fix: SC91275. ---------------- 91/10/8 ----------------------------------------------- Kermit-370 now avoids looping when a solid terminal I/O error sets in or upon any error at the very end of a transfer (no reply expected). The fix: SC91281. ---------------- 91/10/11 ---------------------------------------------- Kermit-370 now uses the built-in default A-to-E translation table for interpreting Kermit commands in server mode when the transfer character set is TRANSPARENT. The fix: SC91284. ---------------- 91/10/22 ---------------------------------------------- Kermit-370 now suggests changes in some settings if the initialization file(s) haven't adopted the new-and-better values. This avoids changing the built-in defaults. The fix: SC91295. ---------------- 91/11/7 ----------------------------------------------- Kermit-MUSIC now determines in advance whether a terminal could possibly be attached to a 3174 AEA before attempting to confirm that, since the attempt itself is risky. The terminal type detection code has been moved to the generic part of Kermit-370, except for a few flags that define system-specific limitations. The tried-and-true optional update SC89058 has been revised and renamed SC9131X accordingly (see above the note dated 89/2/27). The fix: SC91311. ---------------- 91/11/8 ----------------------------------------------- Kermit-370 now has a SIMULATE subcommand, which plays back a file giving one or both sides of a file transfer to supply the packets (instead of the communication line). This facilitates testing new protocol features one Kermit at a time. Lines in the "canned" file are ignored if they begin "S:", are translated from EBCDIC to ASCII if they begin "R:", and are taken as "raw" I/O otherwise. SIMULATE automatically reverts to normal packet I/O either at the end of the file or upon detection of an error. The filespec has the same defaults as for the TAKE subcommand. The fix: SC91312. ---------------- 91/11/12 ---------------------------------------------- Kermit-370 now tolerates alternate EBCDIC versions which do not have all the Roman letters at the standard code points. If the source is passed though a filter that consistently translates certain characters to other code points, the resulting executable program will adopt the same convention, and upcasing and downcasing will follow the new pattern. In particular, this may be necessary in Japan on systems that use the codes normally attached to lower-case Roman letters for Katakana. The fix: SC91316. ---------------- 91/11/16 ---------------------------------------------- The language-specific use of one-letter abbreviations of SET options for program logic flow has been generalized by selecting the internal codes independently of the names of the external options. Any given option could, in principle, be renamed without requiring changes outside of the option keyword table itself. In particular, the keywords could all be translated to a language other than English. Character sets names are an exception, and accented letters should be avoided unless the upcasing and downcasing tables are extended appropriately (see SC91316 above). The fix: SC91320. ---------------- 91/11/21 ---------------------------------------------- Kermit-370 now supports file transfers using Japanese Kanji with translation between IBM, Hitachi, or Fujitsu codes and the newly added transfer character set JAPAN-EUC. Since the new translations require large tables, they have been isolated in a new section of the source code IK0KAN.ASM, which can be omitted. The fix: SC91325. Kanji text differs from other kinds of text files in that it has *two* different character sets associated with it, a single-byte character set (SBCS) and a double-byte character set (DBCS). Thus, it may be necessary to specify the subcommand SET FILE CHARACTER-SET twice: first, for the SBCS and, second, for the DBCS. For example, SET FIL CH CP290 and SET FIL CH FUJ would select one possible SBCS (CP290) along with the Fujitsu double-byte set. Other possible SBCS's are CP281, CP500, and H-EBCDIK-DASH. Plain "EBCDIC" is not currently allowed in combination with Kanji. It is important to specify the single-byte character set first. Note: the chosen SBCS may result in EBCDIC/ASCII translations that differ from those performed by the communications front (for non-transparent modes) -- in that case, it is necessary to SET TTABLE ON in order to transfer files. ---------------- 91/12/18 ---------------------------------------------- Kermit-370 has supported file transfer through the IBM 3174 AEA since release 4.2.1, but some conditions could hang a session after finishing a download. The fix: SC91352. ---------------- 92/1/30 ----------------------------------------------- Kermit-370 has a new FULLSCREEN controller type (the same name as a type that already existed, but served as a synonym for VTAMTTY for historical reasons). The new mode allows Kermit file transfers in a generic way on many different kinds of protocol converters, but it carries some special limitations -- packets cannot be longer than 80 bytes, and the other end must be MS-Kermit 3.12 or higher or possibly C-Kermit 5A.179 or higher. See IK0423.HLP for details on the new mode. The fix: SC92030. ---------------- 92/1/31 ----------------------------------------------- Kermit-370 is now careful to say "unknown" as the reason for cancelling a transfer halted by typing STOP. The fix: SC92031. ---------------- 92/2/21 ----------------------------------------------- The minimum size of strings to be subjected to run-length encoding has been made into a parameter in the Definitions section. The default setting, as before, is 3. Changing it to 2 may be needed to make the new FULLSCREEN mode work on certain protocol converters, such as the MICOM 7400, which convert three successive blanks into cursor motion commands (or even two!). See part C above for such an update. The fix: SC92052. ---------------- 92/3/4 ------------------------------------------------ Getting out of server mode by entering STOP no longer requires hitting ENTER an extra time. The fix: SC92064. ---------------- 92/3/12 ----------------------------------------------- The Hydra II tends to lock up upon receiving an Erase-Write command with no data. Kermit-370 formerly used such a command to condition the screen for an XECHO or XTYPE or to start Kermit protocol mode when DELAY was set to 0. The problem is now avoided by including a single blank in such cases. The fix: SC92072. ---------------- 92/3/25 ----------------------------------------------- Kermit protocol now includes a special checksum type called BLANK-FREE-2 intended to avoid the possibility of multiple blanks in Kermit packets. This can be necessary in FULLSCREEN mode for certain types of protocol converter, such as the MICOM 7400. The fix: SC92085. ---------------- 92/3/26 ----------------------------------------------- The Kermit DIR subcommand now gives the date and time of each file, and the attribute packet for a download carries the correct time stamp. The fix: SC92086. This update is not compatible with MUSIC/SP version 1.2, only with versions 2.1 and higher. See the note dated 92/4/6 in part C for an update to restore compatibility. ---------------- 92/4/22 ----------------------------------------------- Kermit-370 now supports synonym CP1047 for the default file character set EBCDIC, following IBM recognition of the de facto standard and the registration of that character set. The fix: SC92113. ---------------- 92/4/29 ----------------------------------------------- Kermit-370 has changed the calling sequence of the KERMAIL, KERMPRT, and KERMSUB commands that it invokes in support of local mail, print, and job submission. At the first invocation (for verifying that the desired operation is feasible), Kermit passes a dummy filespec consisting of the single character "." instead of passing none at all. The fix: SC92120. ---------------- 92/5/13 ----------------------------------------------- Kermit-MUSIC is now at level 4.2.3. The fix: SC92134. ---------------- 92/6/17 ----------------------------------------------- Kermit-370 has a new TDUMP option available when the assembly-time TRACE option is enabled. Specifying TDUMP TRACE prints a dump of the trace table. Note that the new option is permitted only if TRACE is enabled. The fix: SC92169. ---------------- 92/6/26 ----------------------------------------------- In order to satisfy the restrictions of the F assembler (still used at many sites running CICS under VSE), the TITLE and PRINT ops at the start of open code have been moved after the definitions of global variable symbols. The fix: SC92178. ---------------- 92/8/20 ----------------------------------------------- Kermit-370 now supports the Thai character set. The fix: SC92233. ---------------- 92/12/17 ---------------------------------------------- Kermit-370 now uses TTABLE logic for both the DEBUG and SIM subcommands. The fix: SC92352. ---------------- 93/1/14 ----------------------------------------------- Kermit-370 now prints a nominal efficiency rating in the STATUS report if SPEED is defined. The fix: SC93014. ------------------------------------------------------------------------
