6.8.5 Fake Tape virtual files

6.8.5.1 Function

Fake Tape virtual files contain a complete tape in one file. FakeTape files consist of variable length
EBCDIC blocks. Each block is preceded by a 12-byte ASCII-hex-character header. Filemarks are
represented by a 12-byte character header with no data. The FakeTape format is used by the Flex-ES
system from Fundamental Software Inc (FSI). The argument specifies the location of the FakeTape file
(for example “ickdsf.fkt”). "FLEX-ES" and "FakeTape" are trademarks of Fundamental Software, Inc.

6.8.5.3 Parameter

devaddr

This is the device address.

devtype

This is the device type. Valid device types are 3410, 3420, 3422, 3430, 3480, 3490,
8809 and 9347.

fakefile

The filename (and path) of the Fake Tape virtual file or “*”. An asterisk defines an
empty tape station. The tape must be manually be loaded on request.

If the filename starts with the “@” character (at sign), the file then describes a list of
tape emulation files to be loaded in succession. The syntax of each line in this file is
identical to the information that can be coded directly after the device type in the
overall configuration file. Any emulation file name parameter specified in this file
may be substituted by the character “*”, in which case it specifies a set of options to
be applied to all additional emulation files specified in the list.

This function emulates an Automatic Cartridge Feeder (ACF. The ACF is a feature
on Cartridge type tape drives (3480, 3490, etc..) that automatically loads a new
tape when a tape is removed from the drive. There is no real control over this de-
vice by the host as it just keeps on feeding tapes one after the other. Although the
ACF feature is unique to cartridge type systems, the emulation accepts the use of
