     NAME
          in71 - a filter to read a program from an HP71B

     SYNOPSIS
          in71 [-b] < input_device > output_file

          in71 -?

     DESCRIPTION
          The HP71B Handheld computer, when fitted with the HP82401A
          HPIL Interface can copy files not only to mass-storage
          peripherals but also to any other HPIL device. The format of
          data sent in the latter case consists of a 32 byte header
          which is identical to a directory entry on a LIF volume
          followed by the file date padded out (with arbitrary
          characters) to make it a multiple of 256 bytes.

          in71 strips off the header (displaying some of its
          information to standard error), and (by default) truncates
          the last block of the file, thus recovering the original
          file data. It can thus be used for the direct transfer of
          files from an HP71B to a linux system using (e.g.) an
          HP82164 RS232 interface.

     Options
          -b   Pass the all the bytes of the file, do not truncate the
               last block.

          -?   Print a message giving program usage to standard error
               and exit

     FILES
          hardware/* : Information on linking an HP71B to a PC

     EXAMPLES
          If an HP71B is connected to the linux device /dev/cua0 via a
          suitable interface, then the command

          in71 < /dev/cua0 | hptext

          will read an HP71B text file (sent, e.g. by COPY MYTEXT TO
          :RS232 on the HP71), decode it, and write the result to
          standard output.

     REFERENCES
          The data sent by an HP71B when it copies a file to a non-
          mass-storage device is documented in Volume 1 of the HP71
          HPIL Internal Design Specification
