The MSDOSXFR Program
Note For Advanced Users:
In addition to the above products, the [M=[0=FF program may transfer data to other target devices.
The requirements for performing data transfer from M00=FF are a follows:
e HP-71 can communicate with target device via HP-IL.
e Target device has an accessory ID indicating that it is a mass storage device (between 16 and 31,
inclusive).
e Target device uses Subset/80 command protocol.
eo Target device contains an MS-DOS-format disc (or disc image).
13.3 FORMAT OF TARGET FILE
The MS-DOS file created is a PRN format file, much like that created by a ~FFF command in Lotus
1-2-3®. The file is directly compatible with the ~'FF I command in 1-2-3, and can be easily read into
1-2-3 for further analysis. Lotus 1-2-3 expects a file read in this way to have the . FFI extension.
For this reason, it is recommended that files created by M=[I01= IF be named with the . FFI extension,
although M=00% FF does not force you to do this.
13.4 COMMUNICATIONS BETWEEN HP-71 AND TARGET DEVICE
Before [z= FFE is run, it is important to understand some of the details of communicating with the
target device:
e It is necessary in MZ0=FE for you to specify the HP-IL address of the target device. While
the HP 9114A Disc Drive can be referenced by its device ID( HFY114 ) a host computer
running HPLINK does not have a device ID. It must be referenced by its loop address or by its
accessory ID.
e Many target devices support more than one disc drive. In this case, M=[I5FF will ask which
"unit" is to receive the data. For an MS-DOS machine running HPLINK, unit O corresponds to
disc "A", unit 1 corresponds to disc "B:", etc. For a multiple-unit disc drive, refer to the owner's
manual.
e When running M=[105% FF, the HP-71 is the loop controller. A host computer running HPLINK
is not loop controller, and cannot access other devices (such as disc drives) on the loop.
