- MS-DOS Kermit 2.31 Release Notes, 1 July 1988
-
- This file lists the differences between version 2.31 and 2.30.
-
- A WIDER RANGE OF COMMUNICATION OPTIONS:
-
- - SET PORT COMn (n = 1 to 4). Support for COM1 through COM4 on the IBM PC/AT
- and PS/2 series. Previously only 1 and 2 were supported.
-
- - SET PORT BIOSn (n = 1 to 4). Support for communication ports 1 to 4, using
- Bios-level drivers, like those supplied with certain local area networks.
-
- - SET PORT NET [<nodename>] as in 2.30, for NetBios-based local area networks.
-
- - SET PORT UB-NET1 for Ungermann-Bass Net/One.
-
-
- COMMUNICATION IMPROVEMENTS:
-
- Echoed XOFFs are now detected and no longer cause a deadlock.
-
- Under network operation, files opened read-only now have the DOS DENY-NONE bit
- set so that competing tasks may access them simultaneously, such as when they
- are run by Pushing or RUN within Kermit.
-
-
- FILE ATTRIBUTES:
-
- Kermit File Attributes packets are now exchanged with other Kermit programs
- that know about them. This lets MS-DOS Kermit know the size of incoming files
- in advance, lets it reject them if there's not enough disk space, and lets
- MS-Kermit display the percent done for incoming as well as outbound files.
- Attribute packets also allow arriving files be stored with their original
- creation dates and times. This mechanism has been tested successfully with
- Kermit-370 on IBM mainframes, PDP-11 Kermit, and with MS-DOS Kermit itself.
-
- A new MAIL command, that lets MS-Kermit send a file to a Kermit server with
- instructions (in an Attribute packet) to deliver it as mail to a specified user
- (as yet, no Kermit servers can do this).
-
- USER AND SYSTEM INTERFACE:
-
- A new HELP command was added (just a concise screenful of text, nothing fancy).
-
- CD is now a synomym for CWD.
-
- DO is no longer required to invoke a macro; a macro name can be typed by
- itself... with parameters! (see below)
-
- Improved operation under MS-Windows (screen scrolling via PgUp/PgDn now works).
-
- Error messages have been redesigned to be more helpful, and the command parser
- is more understanding. There is greater consistency among the commands about
- what forms they will accept numbers in, etc.
-
- The Kermit command line interface now permits full 8-bit character inputs, with
- only NUL, ESC, DEL/BS, ^W (delete word), ^U (delete line), and ^C being
- special. This is to enhance support for various languages and keyboards.
-
- Long Kermit commands (e.g. in TAKE files) can now be continued onto subsequent
- lines by hyphenating them. WARNING: This means that if you had lines in your
- old TAKE or initialation files that ended with dash (like "set key \330 -"),
- you should change them by adding a comment or changing the dash to \45, as in
- "set key \330 - ; keypad dash", or "set key \330 \45".
-
- MS-DOS Kermit can now accept commands from DOS files via DOS redirection (as in
- "kermit < todo.lst > todo.log"), or from other DOS processes via pipes (as in
- "sort < todo.lst | kermit").
-
- Kermit's return status code is now user-settable, via SET ERRORLEVEL. Also,
- automatic ERRORLEVEL setting by the SEND command was broken in 2.30, now fixed.
- There is now a transaction log, for recording the progress of file transfers
- (LOG TRANSACTIONS). This is in addition to the session and packet logs
- supported in 2.30.
-
- There are now many new SHOW commands for displaying SET parameters by
- category: SHOW COMMUNICATIONS, SHOW TERMINAL, SHOW PROTOCOL, etc. And macro
- definitions can now be shown individually.
-
- A file TRANSACTION log is available to record the filenames, times and dates,
- sizes, status, etc of files sent or received. The CLOSE command now requires
- the kind of log file to close, such as SESSION, PACKET, TRANSACTION, or all.
-
- TERMINAL EMULATION:
-
- The Tektronix 4010 emulator has been improved and made more like a real
- Tek 4010 terminal. The user may allow Kermit to select the active graphics
- display adapter (default) or may override that choice via the command
-
- SET TERMINAL GRAPHICS Auto-sensing | CGA | EGA | VGA | HERCULES | ATT
-
- ATT includes Olivetti M24/M28/DEC VAXmate/Toshiba T3100/AT&T 6300/6300+.
- VGA invokes a 640x480 dot color display but the bottom 73 lines are not
- saved due to display adapter memory limits.
-
- New Tektronix text overwrites old material without clearing a character cell.
- Echo supression, typically for GIN mode, obeys Tektronix "bypass mode" rules.
- The GIN mode cursor position is remembered. Dots can be given individual
- colors via the ANSI (and Kermit) standard escape sequence ESC [ 3x ; 4x m
- where x is 0-7 to represent the sum of colors, as in SET TERMINAL COLOR.
-
- VT102 screen scrolling has been speeded up the case where the top and bottom
- display lines do not scroll (scrolling regions). A new \Kholdscrn verb has
- been added (VT100 "hold screen"). The VT102 emulator now supports the escape
- sequence pair ESC [ 1 2 h/l to let the host control local echoing.
-
- Ctrl-@ now sends ASCII NUL (0) by default.
-
- VT52 printer-control escape sequences ESC W and ESC X now work.
-
- MS-Kermit's reply to the ESC Z "what are you?" query has been changed from
- "ESC [ ? 6 ; 2 c" to "ESC [ ? 6 c", which is what a VT102 actually reports.
-
- Automatic 132 column support has been expanded to include the EGA/VGA boards
- ATI EVA-Wonder, Everex EV-659 (ega) and -673 (vga), Video 7 VEGA Deluxe (ega)
- and VGA (vga), and Tseng Labs EVA w/132 column kit.
-
-
- SERVER IMPROVEMENTS:
-
- The SERVER command now accepts an optional time limit, to make the server
- shut down after a certain amount of elapsed time or at a given time of day.
-
- The SPACE command no longer requires presence of CHKDSK.COM, and therefore
- no longer hangs the MS-Kermit server if it finds something wrong.
-
- SCRIPT LANGUAGE:
-
- Kermit's script language has been significantly expanded. It has become a
- regular little programming language, similar to what's found in recent releases
- of Crosstalk, Smartcom, etc. Here are some examples:
-
- - Substitutable parameters in macro invocations, similar to DOS Batch.
- - Variables can be defined, referenced, and undefined.
- - GOTO and labels for transfer of control within a TAKE file or macro
- - IF statements for testing conditions including SUCCESS or FAILURE of the
- preceding command (like SEND, GET, RECEIVE, INPUT, etc), or the time of
- day, or whether a file exists, or whether a variable is defined, etc.
- - A loop counting mechanism.
- - A way to reexamine text that has already been INPUT.
- - A way to test for the modem signals CD, CTS, and DSR.
- - Limited interaction with user ("Type any key when ready...")
-
- OTHER CHANGES:
-
- Some internal forward references were juggled so that MS-Kermit 2.31 can
- be assembled with Microsoft MASM 5.1 (2.30 could not be...). However, the
- increased size of some files means that one needs MASM version 4 or later
- to build the sources.

- From: <JRD%USU.BITNET@cuvmb.cc.columbia.edu>
- Subject: File MST23A.UPD (change notes for 2.31/A beta 2 Oct 1988)
-
- MS Kermit beta test 2.31/A 2 October 1988
-
- Corrections and additions following 2.31 1 July 1988 and mid-August
- maintenance release. These apply to all MS DOS machines unless noted
- otherwise.
-
- New to 2.31/A since maintenance release (with affected source files):
-
- - Accept any character, except the start of packet character, in the
- End of Line position of a packet. (msscom.asm)
-
- - Account for file destinations of screen and printer when checking for
- sufficient disk space while receiving files. Correct bug of using incorrect
- disk when checking space available. (mssfil.asm)
-
- - Show current Kermit Connect mode escape character in main HELP display
- rather than just the default Control-]. (mssker.asm)
-
- - Add copyright notice display, to save repeated explanations that Kermit is
- not in the Public Domain, yet it may be distributed at no cost. (mssker.asm)
-
- - Correct file size test for attribute packet, use block device identification
- for bridged or joined drives. (mssrcv.asm)
-
- - Display messages in ACK packets, permit interspersed 'M' message packets.
- Change formatted file transfer screen line "Last warning" to read
- "Last message". (mssfil.asm, mssrcv.asm, msssen.asm)
-
- - Let SET EOF {Ctrl-Z | Noctrl-Z} end of file test apply to TRANSMIT command.
- SET EOF Ctrl-Z now ends the file when a Control-Z is read. (mssscp.asm)
-
- - Correct bug requiring spaces after formal labels and bug clearing VT102
- Connect mode tab stops when CLEAR command is issued. (mssscp.asm)
-
- - Allow TRANSMIT command prompt be a literal ascii character or a \number.
- (mssscp.asm)
-
- - Allow dollar signs in received error messages. (msssen.asm)
-
- - Correct long standing problem of local 8-bit quoting requirment not
- following current operating conditions. (msssen.asm, mssset.asm, mssdef.h)
-
- - Add REMOTE LOGIN {username {password {account}}} command. All three items
- may contain embedded spaces and Kermit non-editing characters. Username
- may be on the same line as REMOTE LOGIN; password and account are always
- solicited via prompts. This command applies only to a remote Kermit server
- and not to a remote operating system; an MS Kermit server does not
- understand the command. (mssser.asm)
-
- - Allow password for REMOTE CWD command to contain embedded spaces and other
- Kermit non-editing characters. (mssser.asm)
-
- - Add one more presence test for AT&T/Olivetti machines in Tektronix graphics
- mode for IBM-PC version of MS Kermit. (msgibm.asm)
-
- - Small internal changes to serial port management details. (msxibm.asm)
-
- - Revise printing strategy within Connect mode to buffer 132 characters and
- to send XOFF/XON to the host while the buffer is written to DOS. This helps
- prevent serial port overruns noted with slow PCs at high baud rates when the
- printer is attached to a network or similar. (msyibm.asm, mszibm.asm)
-
- - Absorb without action the escape sequences ESC * char, ESC + char, and
- ESC <left curly brace> in the VT102 emulator. (mszibm.asm)
-
- - Verify that MS Kermit operates across DECnet using the NetBios emulator
- supplied with DECnet-DOS 2.0 (aka PSCA). The portion of my DECnet-DOS
- startup file MSNET.INI to use NetBios (with a Micom NI5010-1 or a Digital
- DEPCA Ethernet board in this example) reads:
-
- start netbios
- schpc
- dll /irq:5
- dll802 /p:-1 /m:-1 /b:-1 /s:-1
- dnpethpc
- \netrun netbios /msn:-1 /rem:-1 /nbs:-1 /cmd:-1 /lan:0 /nam:-1 /m:e /i2a:-1
-
- Start the network via DOS command NET START NETBIOS. For reasons best known
- to Digital the local machine name is not inserted in the NetBios name table.
- Adding the Redirector via the line
- \netrun redir /*
- does insert the local machine name but prevents Kermit-Kermit communications
- if both sides have this line; I don't know why. Digital has problems.
-
- -----------------------
-
- Changes to MS Kermit 2.31 (IBM-PC) between 1 July and mid-August versions:
-
- - A maintenance release to correct several problems.
-
- - Ungermann Bass Net One support had two fatal bugs, now fixed.
-
- - The Bios in some machines objected to the stray interrupt generated when
- Kermit disconnected from the serial port. Fixed. Also solves problem of
- an earlier task, such as Smartcom II or PC-Talk III, forgetting to replace
- the serial port interrupt it borrowed and causing a crash during Kermit
- operations.
-
- - A serial port with COM2 addressing (port 02E8H, IRQ 3) placed in the
- COM1 Bios data area, such as happens with some PC jrs, could not be
- found. Corrected to switch to COM2 addressing if the Bios data area
- for COM1 is 02E8H. COM1 is normally port 03F8H and IRQ 4.
-
- - The main Kermit command line parser sometimes gave a spurious message
- "?more parameters are needed" when query mark help was used.
-
- - A bug in finding labels in scripts, as in the commands
- GOTO end
- :end1
- commands
- :end
- could let label ":end1" be jumped to by mistake if ":end1" appeared first.
- A note on the label in a GOTO phrase: the label can be a variable name,
- which is immediately replaced by the definition string. The target label,
- however, is not expanded by presence of variable names. Thus, GOTO lab\%b
- is replaced by GOTO lab<definition string of variable \%b> and can be
- used to select labels based on earlier text held in a variable.
-
- - The test for available disk space when receiving files with attributes
- packets inflated the disk space rather than the file size. Revised to
- proper form: inflate file size by 17/16, decline file if not enough
- disk space.
- Additionally, the disk is sought from DOS internal information, rather
- than from the filename string, so that bridged or joined disks can be
- used effectively in the space computation (uses the fundamental device
- rather than a pseudo device letter created by utilities). Thanks to
- Henrik Levkowetz for this as well as the Ungermann Bass material.
-
- - Two commands are present for scripts:
-
- ASK <name of macro or variable> <prompt string>
-
- This displays the indicated prompt and reads a line of text from the key
- board (or pipe if redirected) and stores it in the selected macro or
- variable. A variable (form of \%character) is the more useful of the two.
- The line is echoed and may be edited the same way as a Kermit command line.
- If a comma is entered it is stored in numerical form, \{44}, so that it
- is not mistaken for a command separator but is still a comma when the string
- is sent or used in other ways.
-
- IF [NOT] EQUAL word1 word2 command
-
- The two words are compared for the same spelling, and optionally the same
- case if SET INPUT CASE is set to OBSERVE, and if they match the following
- Kermit command is executed. Modifier NOT may be used to invert the sense
- of the test. Substitution variables may be used in this IF command, but
- if the variable's definition is more than one word it may confuse the
- testing; i.e.,
-
- Kermit-MS> ask \%a Enter your name:
- Enter your name: my name is Chris
- Kermit-MS> if equal \%a Chris goto welcome
-
- is immediately expanded to
-
- Kermit-MS> if equal my name is Chris Chris goto welcome
-
- and fails because the words being compared are "my" and "name", plus the
- command becomes "is Chris Chris goto welcome".
-
- If either word is stated as @filespec then the first word of the file
- is read and used as the test word; this is useful for some username/password
- automation in scripts. If the file starts with @filespec the process nests
- to the final file.
