MAGTAPE (2.x/3.x Only) (Located in C:)
NAME
MAGTAPE [DEVICE devicename] [UNIT unitname] [RET or
RETENSION] [REW or REWIND] [SKIP numfiles]
SYNOPSIS
MAGTAPE was added in 2.x to specifically control the
A3070 tape backup unit. Computer tape drives are
sequential. In other words, All computer tape drives,
like video or audio tapes, must be manually "fast
forward" or "rewind" to get to a particular file.
Random-access devices such as floppy drives, harddrives,
CDRoms, etc directly acess the information.
KEYWORDS
DEVICE devicename
The devicename of unit to manipulate.
UNIT unitname
By default, MAGTAPE accesses SCSI unit four and
utilizes the Commodore scsi.device. This is used because
it is the factory defaults of the A3070. To change the
SCSI unit number of the tape drive, or use a controlling
device other than the scsi.device, you must specify both
the device name of the SCSI controller (eg gvpscsi.device)
as well as the unit number of the tape drive using both the
DEVICE and UNIT keywords. There are usually dip switches
in your unit that can be changed to correspond to any unit
number you like. If you are unsure of the SCSI device driver
your unit uses, then you should call the manufacturer. All
SCSI drivers end in the extension: .device.
RET or RETENSION
This re-tensions the tape by fast-forwarding to the end
then rewinding it.
REW or REWIND
Runs the tape to the beginning.
SKIP numfiles
Unit will run forward past a given number of files.
The variable 'numfiles' tells how many files to skip.
EXAMPLE
1. To rewind a scsi tapedrive attached to a GVP
controller whose unit number is set to two:
MAGTAPE DEVICE gvpscsi.device UNIT 2 REW
