RDREG is a general purpose program to read and interpret the Massbus
|
|
registers in a device connected to an RH20. As such it is useful for
|
|
debugging hardware and software problems related to such devices.
|
|
|
|
RDREG can be assembled to run under both the TOPS-10 and TOPS-20 operating
|
|
systems based on a parameter in the universal file RDRREG. The program
|
|
itself is totally table driven based on tables in the universal file DEFS.
|
|
At present, universal files exist only for the DX20 (DX20.MAC). This file,
|
|
when assembled, creates DEFS.UNV that RDREG searches.
|
|
|
|
To build a program that reads and interpretes DX20 Massbus registers, you
|
|
must assemble RDRMAC.MAC, DX20.MAC, and RDREG.MAC in the following manner.
|
|
First, insure that the parameter "TOPS" in RDRMAC is correct for your type
|
|
of operating system, i.e., 20 for TOPS-20 or 10 for TOPS-10. Then assemble
|
|
RDRMAC.MAC to produce the universal file RDRMAC.UNV.
|
|
|
|
Second, assemble the device specific macro definitions file (in this case,
|
|
DX20.MAC). Note that the result from this assemble is DEFS.UNV; it does not
|
|
have the same name as the source file.
|
|
|
|
Finally, assemble RDREG.MAC. RDREG will search both RDRMAC.UNV and
|
|
DEFS.UNV. The result (RDREG.REL) should now be loaded and saved with the
|
|
name of the type of device it was assembled for, e.g., DX20.EXE for a
|
|
program that interprets DX20 Massbus registers.
|
|
|
|
The program must be run with WHEEL or OPERATOR capabilities enabled on
|
|
TOPS-20 and TRPSET privileges on TOPS-10. When the program is run, it asks
|
|
for the RH20 device code of the RH20 that controls the device. On a
|
|
multi-processor TOPS-10 system, RDREG will also ask for the CPU number to
|
|
which the DX20 is connected. You can find out what the answers to these
|
|
questions should be by asking your field service people. RDREG then reads
|
|
and interprets the Massbus registers for the specified device.
|
|
|
|
You should always run this program on a hard copy terminal so that the
|
|
output can be saved for future reference. In addition, the output should be
|
|
annotated with the date and time and the reason the program was run, i.e.,
|
|
describe the symptoms that caused you to run the program.
|
|
|
|
An example of the output produced by this program when run on a TOPS-20
|
|
system is as follows:
|
|
|
|
@ENABLE
|
|
$RUN DX20
|
|
|
|
RH20 device code: 560
