7.10 RAM Drive Events
The ASG Guard/ASG Guard Plus, in response to certain RAM drive conditions, will generate
events which are part of the standard software/firmware. These standard events are as follows:
.BUFREADY
A buffer file has been closed and is ready to be sent.
.DISKCRIT
The RAM drive has reached the critical level assigned in the Set
Disk Parameters screen.
.DISKFULL
The RAM drive is full and all further writes to the disk are
suspended.
7.11 Utility Programs
Two utility programs are available: CSUM.EXE and ZPAD.EXE.
7.11.1 CSUM.EXE
CSUM.EXE is a DOS utility that calculates an 8-character hexadecimal checksum of a file
Syntax: CSUM <filename>
Example:
C\:>CSUM UPDATE.CFG
Calculate the checksum of the file
UPDATE.CFG
75C2E91A
8-digit hex checksum is printed to screen.
C:\>
7.11.2 ZPAD.EXE
When a file is transmitted with the XMODEM protocol, up to 127 extra characters may be
appended to it. Therefore, a checksum calculated on the file before it is transmitted will not
match a checksum calculated on the received file, because XMODEM changes the file by adding
the extra characters. Run ZPAD.EXE to append the extra characters to the file while it is on your
PC, preventing XMODEM from altering it during transmission. A checksum is calculated after
running ZPAD.EXE and should match the checksum calculated when the file is received via
XMODEM.
