Subject: MS-DOS Kermit v3.16 ready for testing
Date: 17 Feb 98 19:58:31 MDT
Message-ID: <JdQV8BHfzD6y@cc.usu.edu>
Announcing public testing of MS-DOS Kermit v3.16 pre-release.
Experience has shown that interesting bugs appear only when people
really push software, and thus we are asking you to do just that with this
pre-release of MS-DOS Kermit 3.16.
The basic file set is in binary file MSK316.ZIP, 186KB, located in
directory kermit/test/bin on kermit.columbia.edu. There is no installation
instruction nor support scripts etc in this test situation so please use your
existing files. Patches will not work so please comment out instruction PATCH
in your startup material while testing.
Please pass bug reports and comments to Kermit-support@columbia.edu
and send a copy directly to me at jrd@cc.usu.edu.
What's new is indicated in this copy of file msk316.chg. Notice that
some bugs existing in MSK v3.15 are unpatchable and are fixed in v3.16.
We would like to release this edition as soon as bugs are fixed and
our (and your) temptation to add features is restrained (temporarly).
Thanks for helping the project, and we won't charge you to be a tester.
Joe D.
--------------
File msk316.chg -
Changes between the MS-DOS Kermit v3.16 alpha 3 and alpha 2.
15 Feb 1998
1. Write the extra Line Feed to the session log when SET TERMINAL
CR-DISPLAY is CR/LF (CR arrives, act as if CR/LF had arrived).
2. Correct bug in IF statments within SWITCH statments that read too
many bytes for the IF statment command and hence confused SWITCH too.
Changes between the MS-DOS Kermit v3.16 alpha 2 and alpha 1.
24 Jan 1998
1. Correct bug in command SWITCH which resulted in loss of \%1..\%9.
2. Stop a memory leak with keyboard macros.
3. Correct bug whereby command REMOTE QUERY KERMIT would not permit \%char
variables to be replaced with their definition in the command argument.
4. Add command REMOTE SET TRANSFER MODE {AUTOMATIC, MANUAL}.
5. Correct a serious problem of sending incomplete Kermit packets over a
serial port connection.
6. Add display of optional message on the QUIT and EXIT commands.
Changes between the MS-DOS Kermit v3.15 and v3.16 alpha 1.
8 Dec 1997
1. Correct bug in IP intruder detection (conflicting IP addresses).
2. Correct bug which times out active TCP/IP Listen connections.
3. Correct bug which disabled use of macro on_exit.
4. Add TCP delayed ACKs to reduce network traffic on busy links. The
delay is nominally 50ms. This heuristic may be removed later.
5. Extend TCP reply timeout to several minutes, for especially slow links.
6. Turn off Kermit packet level timing during file transfers over internal
TCP/IP. This heuristic is subject to modification later.
7. Add granularity to command SET TCP DEBUG {OFF, STATUS, TIMING, ON}.
ARP packets and round trip timing appears only with TIMING and ON.
TCP states and normal operating messages appear with STATUS and ON.
ON means both STATUS and TIMING.
8. Add an 8KB autocache for reading disk files during file transfers.
9. Add fast block-mode byte transfers while reading Kermit packet data
field bytes, as a speed improvment on fast comms links.
10. Allow binary 0 to appear as an unprefixed code in Kermit packets.
11. Enforce prefixing of codes 127, 255, packet start of header (normally
1, Control-A), packet end of line (normally 13, Carriage Return),
and 3 (Control-C).
12. Revise SHOW CONTROL-PREFIXING to display both prefixed and unprefixed
control codes.
13. Add Kermit protocol streaming mode. SET STREAMING {ON, OFF}, default
is off. Heuristics are still being adjusted. STATISTICS command has a
new field saying streaming was used on last file transfer. Formatted
file transfer screens show streaming rather than windowing information.
Fastest transfers use SET DISPLAY QUIET (reduces per-packet overhead)
and the file sender uses SET CONTROL UNPREFIX on as many codes as the
comms channel will support (but always prefix Control-C (3) and packet
start (1) and end (13) codes and their high-bit-set counterparts, plus
Telnet 127 and 255. In short form: set control unprefix all, set control
prefix 1, 3, 13, 127, 129, 131, 141, 255).
14. Remove command SET RECEIVED IGNORE-CHAR for being obsolete and awkward.
15. Add command SET TRANSFER CRC {ON, OFF}, default is off, and variable
\v(crc). This calculates the CCITT-16-CRC checksum across all files
sent or received in a group.
16. Add new options /RECURSIVE and /NONRECURSIVE to the SEND and GET commands
to send or request files from directory trees. Default is /nonrecursive.
MS-DOS Kermit Server mode also supports recursive requests. Directories
are created as needed. Recursive requests can be rooted or relative to
the current location depending on the filename pattern given. The syntax
is SEND /RECURSIVE filespec and so on; a /switch is optional.
17. Add functions \frdirectories() and \frfiles() to support recursive tree
walking. \frdirectories(pattern) yields the number of directory names
in the tree fitting the pattern, and \frfiles(pattern) does the same for
filenames. Function \fnextfile() remembers whether the recursive or plain
file counting functions, \frfiles() or \ffiles(), were invoked and it
produces a new filename accordingly on each call.
(End)
Frank again. Many of these features -- streaming, recursive directory
traversal, unprefixing 0 -- parallel those in C-Kermit 6.1 and
K95 1.1.16, both of which are yet to be announced, and can be used in
conjunction with those versions as soon as they are available. Watch
this space and/or the comp.protocols.kermit.announce newsgroup for
further news.
