Kermit-370 4.3.x "Beware File" - Known Bugs, Problems, Limitations. As of: 20:15pm Wednesday, 1995 May 31 The following is the generic BWR file -- most BWR entries, however, are system-specific. See the system-specific BWR for more information. Note that Kermit-370 release numbers are three-part (e.g., 4.3.0) and should be reported in full in any bug reports. ---------------- 90/5/8 ------------------------------------------------ A commonly reported "problem" is that Kermit-370 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-370 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-370 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). ---------------- 90/5/8 ------------------------------------------------ With a few exceptions, CONTROLLER will be set automatically when Kermit is invoked. Kermit-370 has been reported or rumored to work with many different types of front end. See IK0AAA.HLP for a current list. ---------------- 90/5/8 ------------------------------------------------ A new restriction has come to light concerning Kermit through Renex protocol converters, such as the TMS-1. It is necessary to make sure that typeahead is turned off in order to let graphics passthrough work. It may also be necessary to set the parity to MARK on both Kermits in both directions, thereby limiting the data channel effectively to a 7-bit width. ---------------- 91/10/10 ---------------------------------------------- Kermit-370 now supports the "end-of-attributes" attributes. If that causes the other Kermit to refuse files (or worse, as has been found in the case of Kermit-11), the new attribute can be suppressed by issuing SET ATTRIB END OFF to Kermit-370. N.B. The End attribute must be turned on in order to use level-1 recovery of a partly-transmitted file. ---------------- 92/4/28 ----------------------------------------------- When a file transfer or server mode ended, and the user reconnected back from MS-Kermit to the mainframe, the screen was (in the past) left with the "greetings", and it was necessary to refresh or clear the screen. That is no longer needed for versions of MS-Kermit 3.12 and higher. ---------------- 92/9/9 ------------------------------------------------ When the file character set is changed to one of the Kanji sets, and the previous setting was not one of those allowed with Kanji (CP290, CP500, CP281, and H-EBCDIK-DASH), the Kanji set is normally paired with the first of those (CP290), but the choice may be altered by changing the order of character sets listed at label TBVJP -- the first set is the default. For example, to change the default to CP281, use the following update: ./ * SC92252 - Make CP281 the default SBCS with KANJI ./ R 04118000 $ 4118000 100 10/18/91 ->4.3<- TBVJP DC CL(LALF)'CP281',CL(LALF)'CP500',CL(LALF)'CP290' @SC92252 ---------------- 94/11/15----------------------------------------------- Kermit-370 version 4.3 contains SETA instructions in open code that use count attributes. These are not permitted in open code by certain old assemblers. If your installation uses such an assembler, the following update provides compatibility. ./ * SC94307 - Move count attributes into a macro for old assemblers ./ I 00756000 $ 756050 50 11/03/94 17:29:08 *COPY GBLDEFS @SC94307 MACRO @SC94307 GBLDEFS &FSPCPRM,&OPRMUB,&OPRMUL @SC94307 .* Generate language-dependent constants @SC94307 GBLA &FMTOPT,&LOPRNUM,&LOPRMUS,&MSGFILL @SC94307 &FMTOPT SETA K'&FSPCPRM Length of "[first-last...]" @SC94307 &LOPRNUM SETA K'&OPRMUB Length through "be " @SC94307 &LOPRMUS SETA K'&OPRMUL+&LOPRNUM Total length @SC94307 MEND @SC94307 ./ D 01431000 11/03/94 17:24:27 ./ D 01431600 01431800 11/03/94 17:24:27 ./ I 01432400 $ 1432500 100 11/03/94 17:24:27 GBLDEFS , @SC94307 ---------------- 95/2/2 ------------------------------------------------ Kermit-370 has a feature that allows it to respond immediately with an error message if the file name given on a RECEIVE subcommand is invalid or conflicts hopelessly with existing file(s). This immediate handling of possible errors prevents Kermit-370 from handling level-1 recovery for a partly-received file. Such recovery works only if the name is supplied by the other Kermit. ---------------- 95/5/30 ----------------------------------------------- Kermit-370 deals with full-duplex SNA lines by issuing a SNA Inhibit Presentation control character when entering protocol mode. This is intended to inhibit the echoing of all the inbound packets during file transfers. However, it may have the additional effect on some systems of inhibiting outbound packets, effectively stopping any transfer. To avoid this problem, the following update can be applied. ./ * SC95150 - Avoid SNA presentation commands ./ D 08771500 05/30/95 18:55:38 ./ D 08784500 08786500 05/30/95 18:55:38 ------------------------------------------------------------------------
