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

---------------- 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
