DTELDR.DOC -- Changes from V2(26) to V4(35)
July 1979
1.0 SUMMARY
DTELDR is a program to dump and bootstrap front ends connected to the
KL10 (1080 to 1099 systems) via DTE20s. This release of DTELDR will
support DN20s on 1091 systems. The console line of a DN20 is
connected to a line on the master front end instead of a terminal as
on a DN87S. A pending ECO will do the same to DN87Ss sometime in the
future and will be installed at field service's discretion. The new
DTELDR features will not affect DN87Ss until TOPS-10 7.00.
DTELDR will run on all TOPS-10 KL based systems under 6.03 and later
monitors. There is no point in running DTELDR on KA or KI based
systems.
System notebook documents that reference DTELDR include the Networks
Software Installation Guide and the DECsystem-10 Operator's Guide.
2.0 EXTERNAL CHANGES
DTELDR now logs all loads and dumps of front ends in ERROR.SYS.
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
Refer to DTE2.DOC.
5.0 INTERNAL CHANGES
DTELDR now performs a DAEMON UUO to log all reloads in ERROR.SYS.

Operator's Guide (AA-51504A-TB).
2.0 EXTERNAL CHANGES
The major change in this release is to attempt to log CHK11 and other
output from DN20s on the terminal controlling DTELDR. This is
possible by the hardware configuration of DN20s and eventually DN87Ss.
These communication front ends (FEs) have their console DL11 line
connected to another DL11 in the master front end (RSX-20F). Thus
output to a comm. FE CTY shows up as input to the DEC-10 and DEC-10
output shows up as input to from the FE's CTY.
If DTELDR is used as version 1 was, all comm. FE output (e. g. CHK11)
will be intercepted by the DTELDR running in automatic mode and
printed on its terminal. Two new switches modify this operation.
2.1 /IGNORE:XY:XY:...:XY
This switch takes a list of FEs and will ignore anything that happens
to them and will not access their CTYS. This command is useful mainly
to system programmers who don't want a FE they are debugging
automatically reloaded.
2.2 /NOLISTEN:XY:XY:...:XY
This switch also takes a list of FEs and tells DTELDR not to access
the FE's CTY line except when reloading the FE. This is useful for
systems programmers who want FEs automatically reloaded but also want
total access to a FE for their own needs.
DTE2.DOC Page 4
Both these swtiches leave the CTY lines of all FEs referenced
available to any job and should not be used except by sites without
problems from malicious users. Once used, the only way to undo the
effect of these switches is to CTRL/C DTELDR and restart it.
2.3 /TALK:XY
This switch may be used either alone or with the /AUTOMATIC or /RELOAD
switches. When used alone, it takes a single FE as an argument and
will "crosspatch" the controlling terminal to that FE's CTY. This
allows users to talk to diagnostics and debuggers. The only way to
break the crosspatch is to CTRL/C DTELDR and then restart or reenter.
When used to modify /AUTO or /RELOAD, /TALK does not accept an
argument. These commands will enter talk mode when new code is loaded
(the initializing message) and leave when the code requests to start
primary protocol (the "started" message). If used with /RELOAD,
analogous operation will occur except that no timeout will occur while
waiting for primary protocol to start since the user is in control of
the situation.
2.4 Minor changes
All messages of the form "PDP-11 loading", "PDP-11 started", etc. are
now of the form "front end XY loading". This will make automatic mode
more informative.
DTELDR will no longer send the "front end XY has just been reloaded"
message to OPR since DTELDR messages normally print on OPR anyway.
DTELDR will now load FEs on any CPU (this depends on release 7.00 of
TOPS-10).
3.0 KNOWN BUGS AND DEFICIENCIES
None.
4.0 INSTALLATION INSTRUCTIONS
Unchanged since release 1 (see section 4.0 in DTE1.DOC).
DTE2.DOC Page 5
5.0 INTERNAL CHANGES
The major change to implement communication with the FE CTY lines was
to build a data structure for each FE that can possibly exist in a
system. For each FE (including RSX-20F FEs) there is a DTE control
block (DTB). Information in each DTB includes flags, ASCII and binary
representations of the FE, the UDX of the FE's CTY line (if any), and
a line assembly buffer for data from the FE.
Since DTELDR has to maintain open IO channels across commands, (i. e.
a MPX channel used to listen to FE CTYs), the restart logic has been
cleaned up so that it no longer has to use a RESET UUO after each
command.
6.0 SUGGESTIONS
The major suggestion is to log CHK11 output in ERROR.SYS.

DTELDR.DOC -- V1(21)
December 1976
1.0 SUMMARY
DTELDR is a program to dump and bootstrap front ends connected to the
KL10 (1080 or 1090 systems) via the DTE20. Presently, this includes
the KL Front End (RSX20F) and the DN87S in TOPS-10 6.03.
DTELDR will run only on 6.03 and is required to run on all 1080 or
1090 systems.
2.0 EXTERNAL CHANGES
As DTELDR is an entirely new program, the HELP file is reproduced here
in its entirity.
DTELDR is a program to dump and bootstrap front ends connected to the
KL10 via a DTE20. Command format is:
*DEV:FILE.EXT[P,PN,SFD,SFD,. .]/SWITCH/SWITCH
or
*/SWITCH/SWITCH
DEV:FILE.EXT[P,PN,SFD,SFD, . .] is the file specification for the
file to load into the -11. Default is DSK:DTEL<X><Y>.BIN, where <X>
is the CPU number (only 0 allowed in current implementation) and <Y>
is the DTE number (0,1,2 or 3). This specification is only meaningful
if the -11 is loaded over the DTE20. (See /SWITCH)
Dumps are written out to DSK:DTED<X><Y>.BIN, .B00, .B01, etc. Using
path of job that runs DTELDR.
Action switches: (<FE#> indicates front end number, <CPU#><DTE# from
0-3>
/AUTOMATIC - automatically reload front ends that crash
/HELP - type this text
/TERMINATE:<FE#> - shut down specified front end
/RELOAD:<FE#> - reload specified front end and start primary protocol
/INITIALIZE:<FE#> - start primary protocol on specified front end
Modification Switches:
/IMAGE - .BIN file is in image format
/NODUMP - do not do dump of -11 core
/SELECT:<10,11> - select place to reload -11 from
/SWITCH:<VALUE> - use octal <VALUE> instead of old -11 switch value
/NOLOG - suppress error logging
DTE1.DOC Page 7
A DUMP file specification may be given for /AUTOMATIC. The switches
/NOLOG, /NODUMP, and /SWITCH may also be specified with /AUTOMATIC.
/SELECT:10 reloads the front end over the DTE20 from the reload file
specification. /SELECT:11 reloads the front end from the -11 device
specified in /SWITCH, or from the original -11 load device if /SWITCH
is not specified.
If /SELECT is not given, default is "11" if the -11 is the master,
"10" otherwise.
/TERMINATE and /INITIALIZE must not appear with any other switches.
/SWITCH is used when the reload source is the -10 to tell the ROM
which -11 device to obtain the reload file from. RSX20 also uses the
switch setting to determine whether to enter KLINIT or not.
Masks for Values:
3400 - unit number field
200 - If one, use RP04. Otherwise, use Floppy or DECtape,
in that order (with BM873-YH ROM)
7 - KLINIT Field
0 - Ignore Switches
1 - Enter KLINIT, give default answers to questions
3 - Do not enter KLINIT
5 - Same as 3
7 - Enter KLINIT dialog
3.0 KNOWN BUGS AND DEFICIENCIES
There are no known bugs or deficiencies in this version.
4.0 INSTALLATION INSTRUCTIONS
The DTELDR package contains the following files:
DTE1.RND
DTELDR.HLP
DTELDR.MAC
DTELDR.CTL
DTELDR.EXE
Since DTELDR only works on a 1080 or 1090 system there is no need to
install it on other systems. For systems that need DTELDR, its .EXE
file should be put on SYS: and the .HLP on hlp:. Systems that do not
have a DN87S should add the following to OPR.ATO to provide for the
automatic reloading of the console front end processor.
DTE1.DOC Page 8
:SLOG
:DEF DTE=
DTE-R DTELDR
DTE-/AUTO
Systems with DN87S's must also add INITIALIZE switches for the DTE's
they are connected to. For example, a site with 2 DN87S's, one on DTE
#1 and the other on DTE #2 should have in their OPR.ATO :
:SLOG
:DEF DTE=
DTE-R DTELDR
DTE-/INIT:1
DTE-/INIT:2
DTE-/AUTO
5.0 INTERNAL CHANGES
As DTELDR is newly released, this section is not applicable.
6.0 SUGGESTIONS
None.
