B. Backup Utility Types
1.00 Before Beginning Backup
It will not be possible to save or load the system
programming data and attendant console
database correctly if the backup device's
communications settings are not correct.
1. Are the baud rate, number of data bits, stop
bit and parity settings correct? They must all
be the same as the settings on the system
side. (Is there a communications format
setting? This must be set to full duplex.)
2. Is the backup device set up to sent X-on/X-off
codes to control the flow of the data from the
system? (X-on/X-off send) Also, is it set up to
receive X-on/X-off codes sent from the system
to control the flow of the data sent to the
system?
Both are essential.
3. Is the backup device set so that all control
codes corresponding to ASCII 00h-1Fh are
transmitted and written to the storage device?
Also, is the backup device set so that these
stored control codes can be sent without
limitation to the system?
The above settings are necessary to ensure
that the SOH, STX, EOT, ETX codes, etc.
specified in the transmission format
correspond to the control codes.
In addition, in order to perform a backup with
a protocol, the backup device must be set up
so that all codes form 00h-FFh are received,
stored and transmitted.
4. Does the setup specify automatic linefeeds
(the linefeed code is automatically added to
the data each time the data displayed reaches
the 80th column at the far right of the
screen)? If this function is enabled, the large
number of extra codes added to the data will
produce an "Illegal code detect" error
whenever data is loaded. The automatic
linefeed function must therefore be turned off.
