BBC KERMIT 1.33
===============
BBC Kermit 1.33 is now online. This is a bug fix release with no new facilities
over the previous release 1.30. Problems cured are:
- Reverse screen scrolling in VT52 mode now works correctly. This was a bug
in OS1.20 which has been circumvented. I am not particularly happy with
the appearance of the result, and as time permits I shall try to improve
the way this and similar operations are handled.
- Function keys are reset to their correct power-on defaults on EXIT or OS
command. This cures a problem whereby WordWise users found that
SHIFT-Cursor
did not work after using Kermit
- A lost ACK to an S packet sent by BBC Kermit is now handled correctly.
- BBC Kermit will now talk to systems that send pad characters between the
block-check and the end-of-packet marker.
-----------------------------------------------
BBC KERMIT 1.42
===============
BBC Kermit version 1.42 for models B, B+, B+128 and Master 128 is now
available. The features and changes in the new release are as follows:
- The Master 128 is now fully supported, the minor incompatibilities which
existed in version 1.33 being cleared.
- ADFS is now fully supported. BBC Kermit will generate local file names of
length appropriate to the selected filing system.
- The character used when modifying non-unique names has been changed to be
a "+" as "&" is not legal under ADFS or some Econet file server systems.
- The disc based version will utilise the shadow screen on the B+, B+128 and
Master 128 and will provide a VT52 terminal emulation.
- The SET VT52 and SET VDU-WIDTH commands are removed, and a new command SET
TERMINAL introduced. This takes a parameter describing the emulation
needed, which can be one of TT40 or TT80 for teletype emulations, or VT52.
For future use, additional types of VT100, TEK, A and B are also
selectable but will not, of course, be usable (see below).
- The default terminal type will be set automatically from the machine type.
The ROM version will default to VT52 always; the RAM version will default
to VT52 on the B+, B+128 and Master 128, and to TT40 on the B.
- Files are no longer closed on entry, so that the system can be started
from auto-boot with set up commands in the !BOOT file. A new command CLOSE
alllows all open files to be closed if this is necessary. Since there are
now two commands beginning with "C", a new command "C" has been provided
as a synonym for CONNECT, so that the commonly-used abbreviation will
still work.
- The RAM version now sets OSHWM to lie above the program image, so that
commands such as *COPY will not destroy the program. The mode to be
selected on reset is changed to 7 to avoid corruption when BREAK is
pressed. Note that the change to OSHWM is not undone if, for example, a
*BASIC command is issued to leave KERMIT: the EXIT command shoud always be
used.
- CONTROL-BREAK now exits the RAM version.
- The code for sending break levels on the comms line has been changed and
should reduce or eliminate the garbling that occurred in earlier releases.
- A new command SET FILE NAME controls how file names sent by a remote
Kermit are handled. NORMAL, the default, treats them as "name.type" as
before; UNTRANSLATED uses the name exactly as sent, so it must be a legal
BBc file name.
- User vectors have been removed (no-one responded to a newsletter question
on whether this feature was used). The JSR command had been removed on the
pre-release 1.40n versions, but has been re-instated.
- A file being received from a remote Kermit is now correctly deleted if the
remote sends an EOF(D) packet.
- An ACK(X) or an ACK(Z) in response to a data packet sent by BBC Kermit is
now handled correctly.
- The system no longer forces selection of the parallel printer, so debug or
file transfer to network printer should now work. It's up to the user to
make sure he doesn't have the serial printer selected!
- OSBYTE calls with A=70 (decimal) are now used by BBC Kermit, so there may
be interactions if run in a machine with another ROM that responds to this
call.
- The bug in DFS 2.24 on the Master 128, which affects the OSFIND call to
close all files, is substantially circumvented, but the real solution to
this must be to obtain DFS2.25 or remember to use the correct release of
the CONVERT utility.
- The source is now compatible with both the ADE assembler and the free
65C02 assembler distributed with it. A question is output at the start of
an assembly to determine which is being used.
- A new command, TRANSFER, allows raw uploading of files with full flow
control to systems without Kermit.
- The Master 128 keypad is used in VT52 mode to emulate a real VT52 pad.
Version 1.42 also contains code to make use of terminal emulation in other
ROMs. The main program (both ROM and RAM versions) will make a service call
with OSBYTE 70 if the currently-selected terminal type is not one they support:
the Terminal Extension ROM may take the call and provide terminal emulation if
it wishes.
From this version on, the source can be assembled with the Lancaster 65C02
Sideways-RAM/ROM based assembler, supplied free with BBC Kermit. The
commercially available ADE assembler can still be used, but the Lancaster
Assembler is the preferred tool to use.

BBC KERMIT VERSION 1.43
=======================
This is a minor bug fix release. Version 1.42 and earlier all suffered from a
bug in handling the receive-quote character (with B7 set) sent from the remote
side if 8th- bit prefixing was not in use. The symptoms were that the character
would be stored in the file with B6 inverted.
As the default mode of operation of BBC Kermit is to select space parity and
hence always try to negotiate the use of 8th-bit prefixing, it took a long time
for this bug to come to light.
Thanks to Arjen Raateland of Helsinki, Finland for pointing the bug out.
------------------------------------------------------
BBC KERMIT 1.44
===============
BBC Kermit 1.44 is a minor bug-fix release that contains no new user facilities
The changes from version 1.43 are as follows:
- Quoting and 8th-bit-prefixing are done correctly in G packets (i.e. those
containing the command strings generated by the REMOTE command.) In previous
versions, for example, any REMOTE command such as REMOTE DIR ABCDEF, which
generated a 6-character sub-field, would fail to pass the field length byte
correctly.
- REM CWD now sends the password correctly.
- Bit 7 (the parity bit) is now stripped from all bytes received from the
remote system in terminal mode, before they are output to the screen.
- Wildcard file send will now not attempt to send any files that are in fact
sub-directories (on ADFS for example). Sub-directories can still be sent as
files if they are named explicitely.
---------------------------------------------
BBC KERMIT 1.45
===============
BBC Kermit 1.45 is now available. This corrects a serious bug that appeared in
1.44, which prevented it talking to Kermit servers if 8th-bit-prefixing was
not in use. Any server command would immediately fail with a message "Too
many retries", with only the I packet interchange being done.
