Problem:
.run k10mit
TOPS-10 KERMIT version 3(134)
Kermit-10>set file (parameter) byte-size (to) 7
? Unrecognized switch or keyword: "7"
Kermit-10>set file (parameter) byte-size (to) ? one of the following:
7-bit 36-bit 8-bit auto-byte eight-bit
seven-bit thirty-six-bit
Diagnosis: The command table is not sorted properly. The new "36-bit"
parameter comes after "7-bit". It should be vice versa.
Cure: exchange two lines in the table FBS020 in K10MIT.MAC
[Ed. - Thanks, change made in K10MIT.MAC source.]

Re: Bugs/Bug Fixes for Kermit-10
Have discovered/fixed two bugs in Kermit for the DECsystem-10.
Both occur in the MACRO-10 module K10MIT.MAC.
(1) The new byte-size "TIRTY-SIX-BIT" does not work.
Cause: In routines GET%FILE and PUT%FILE, when checking for operation in
36-bit mode, the wrong symbol is used in the comparison instruction.
Fix: In routines GET%FILE and PUT%FILE, substitute the symbol $FBS36
for $FBS8 in the mode comparison instructions. Also fix comment
in the routine PUT%FILE to correctly reflect the results of the
test for the presence/absence of the high-order bit in a character.
(2) In the routine T$CON which connects a terminal, when checking
for connect to a non-network terminal, the wrong flavor of a compare
instruction is generated by a CAX?? macro expansion.
Fix: Place an extra pair of angle-brackets around the 2nd operand to the
CAX macro so that the comma in the XWD pseudo-op argument doesn't
confuse expansion of the CAX macro.
I have not changed the edit-numbers as I was not sure of the editing
scheme it was desired to use (for example, although edit 134 is mentioned
in the .MEM files which accompany the DECsystem-10 Kermit distribution,
KEREDT is set to 133 in my copy of K10UNV.MAC.
Below is a FILCOM showing the differences in the code between the released
K10MIT.MAC and the corrected version:

2) JRST TCON.E ; No, some other error
**************
Incidentally, the impending demise of VMSMIT Kermit (Kermit-32) raises
the question of the fate of Kermit-10, although it could be argued that it
will be doomed anyway with the slow and painful death of the KL10. What of
support of Kermit-10?
Keep up the fine work you are doing for the Kermit community.

Diagnosis: If a system-wide Kermit initialization file (INI:KERMIT.INI) has

Problem: When Parity is set to None and the Block-check-type is set to
3-Character-CRC-CCITT, binary file transfers between Kermit-10 and
Kermit running on microcomputers either fail or are incorrect.
Diagnosis: In the module K10MSG.BLI, in the routine CALC_BLOCK_CHECK which
calculates the block-check for a character-string, in the code for THE
case in which the 3-Character-CRC-CCITT is used, there is an IF-clause
which specifies the circumstances in which only seven bits of each
eight-bit character are to be used in the Block-check calculation.
As distributed, high-order bits of characters are to be ignored
when Parity None is in effect. This is incorrect. The high-order bit
of each character should be ignored when Parity is set to anything but
None.
Cure: In the module K10MSG.BLI, in the routine CALC_BLOCK_CHECK,
in the 3-Character case, change the EQL in the IF-clause to a
NEQ. A FILCOM showing the required change is shown below:
File 1) DSKE:K10MSG.BLI[10,50] created: 1705 19-Aug-89

1)45 IF .PARITY_TYPE EQL PR_NONE
1) THEN
****
2)45 IF .PARITY_TYPE NEQ PR_NONE
2) THEN
**************
In the Macro-10 module K10MSG.MAC generated from K10MSG.BLI, the
required change is accomplished as follows: (a) in the Bliss code
which appears as Macro comments, in the routine CALC%BLOCK%CHECK, in
the code for the 3-Character-CRC-CCITT case, in the IF clause, change
the EQL to NEQ to correctly reflect the program logic.
(b) in the Macro-10 code for this routine, change the statement
TRNN AC2,1
which follows label L342: to
TRNE AC2,1
Since I do not posess a Bliss-36 compiler, I am uncertain that this
is the *exact* code that would be generated with this logic change
but would assume so since, at this point in the program, AC2 is being
used as a flag to indicate that Parity None is in effect.

Re: Updated Helpfile for TOPS-10 Kermit
I have updated the help file for TOPS-10 Kermit, K10MIT.HLP, to reflect
the latest version of Kermit-10 (Version 3(134)). The file includes
text showing the THIRTY-SIX-BIT file byte-size as well as long packet
support. A FILCOM of the original help file (as found on OKSU dial-up)
with my revision is shown below, delimited by lines of asterisks.
Following this, delimited by asterisks, is a .COR-file (K10HLP.COR)
produced by the TOPS-10 program COMPAR, which, when applied to the
original file K10MIT.HLP with the TOPS-10 program UPDATE, will produce
an updated help file. Incidentally, I had to do extensive reformatting
of the source-files (MACRO-10 versions) as found on OKSU due to <CR><LF>
pairs being inserted in many places when lines were longer than 80
characters (which raised havoc with compilation). In order to make this
version function properly, one should also make my modifications to
K10MIT.MAC to fix bugs in handling of .INI-files, the THIRTY-SIX-BIT byte-size
and NODE. UUO arguments.
Thanks for the latest newsletter.
keep up the good work.
Send E-mail to me with BITnet address mailer@uwalocke with the message subject
dec10%"bpa". This is necessary to get the mail from the BITnet node uwalocke
(a Vax) to the DECsystem-10 to which I have access.

He called back today and said he'd solved the problem. He used
DDT, a tops-10 macro debugger, and ended up commenting out two lines in module
T$CONN: (which I see is in the file k10mit.mac). The two consecutive lines he
commented out are:
CAXE S1,<XWD .NDTCN,T1> ; Non-network system?
JRST TCON.E ; No, some other error
He says the problem was "the tty was an invalid tty", removing those two
lines fixed it for him. FYI.

Subject: Kermit-10 Problem
Well, I wonder if he's got the latest version of Kermit-10. As I recall, I
ran into this when I tried to compile the latest Kermit-10 (the one with
extended-length packets) and the problem was due to some lines in K10MIT.MAC
having been broken up in transmission to watsun. I've uploaded corrected
files. Have the gentleman FTP ~/kermit/b/k10*.mac to his site and try again.
If he's still having trouble, let me know and I'll look into it.
Alternatively, I can E-mail you a little Fortran program to run on the Ten
along with an ASCII representation of the SIXBIT translation of KERMIT.EXE
from our site that he can use the program to convert back into KERMIT.EXE and
try out. We won't be a DECsystem-10 site much longer (sigh) so after a few
more weeks won't be able to help him directly (though I'll keep source around
for awhile). BTW, the versions of the Galaxy universals used by K10MIT.MAC
aren't the latest ones -- they changed the def of the STOPCD macro so MACRO
complains using the latest ones. I can supply translated versions of the one's
K10MIT.MAC likes if needed.
By the way, those lines can be left in if <> is replaced by <<>> -- so that
the arguments to the macro get translated properly (later as one arg rather
than two).
