Greetings,

	I am trying to do some simulations on CRC codes.  I have found several
sources that have code for generating CRC's.  The only problem is that
these algorithms are based on 16 or 32 bit CRC's and table lookups.  I
would like to be able to use a 4 or 8 bit CRC.  I have not
been able to successfully figure out how to convert these algorithms
to an arbitrary length CRC.  The tables (XOR's with the generator and
all possible one byte data characters) are used for efficiency.  I'm
not so concerned about speed.  I just want to be able to change the 
CRC generator polynomial.  I can run my simualtions overnight so the 
time wasted using bit shifts to compute the CRC the way hardware does
is ok.

If you can help please e-mail me at  RENEGADE@DNACO.NET

If anyone using Linux is interested in scripts to connect to the 
Internet via PPP also let me know.  I have developed perl
scripts to make a PPP connection to the Internet.  These
scripts will re-dial if the line is busy, and can handle dynamic IP
addressing.

	Thanks in advance,
