    The files above are the CMU PCIP package. In addition to those you
    will need the ARCNET-specific files (be careful when extracting as
    some member filenames are the same as those in other ARCs).

    Filename Type Bytes CRC

    Directory PD1:<MSDOS.ARCNET-PCIP>
    ARCNET.ARC.1 BINARY 19889 4B5CH
    ARCNET-RFC.TXT.1 ASCII 5622 E04CH
    CUSTOM.ARC.1 BINARY 16061 8391H
    INCLUDE.ARC.1 BINARY 9294 7B81H
    INTERNET.ARC.1 BINARY 17017 A921H

I will take this chance to clarify a few things (my fault: I was
too lazy to write a README). The ".ARC" extension means ARChive,
the format the files are grouped as; previous users of SIMTEL20
will recognize this. The first two files above are the device
driver for an ARCnet interface (PDI, DATAPOINT, or SMC) and the
accompanying RFC that describes IP over ARCNET. CUSTOM includes
some generic modifications to support memory (not IO) mapped
devices (which ARCNET IFs tend to be). INCLUDE and INTERNET
are changes to the standard distribution that offer increased
functionality to IP and ICMP -- some of that functionality was
required to support ARCNET, but is not ARCNET specific. For
instance, fragmentation/reassembly had to be added to get decent
performance out of ARCNET, but will work equally well with
pronet, ethernet, and token ring. The files in INCLUDE, INTERNET,
and CUSTOM are meant to replace their counterparts in the CMU
distribution in \INCLUDE, \SRCLIB\INTERNET, and \SRCCMD\CUSTOM
respectively. You may want to back up these files before
replacing them.

Enjoy,
