CYCLICAL REDUNDANCY CHECK UTILITY Release Level SAT JAN 02 1993 12:49PM This application consists of one runfile: CRC.Run Product Name : CRC Supported On : B24, B26, B27, B28, B38, B39, and all SuperGen hardware Supported OS : BTOS II, CTOS I, CTOS II, CTOS III Description : This program allows the computation of a 32-bit CRC of a list of files. Directions/Use : Program to compute the 32-bit CRC used as the frame check sequence in ADCCP (ANSI X3.66, also known as FIPS PUB 71 and FED-STD-1003, the U.S. versions of CCITT's X.25 link-level protocol). The 32-bit FCS was added via the Federal Register, 1 June 1982, p.23798. FIPS PUB 78 says that the 32-bit FCS reduces otherwise undetected errors by a factor of 10^-5 over 16-bit FCS. The polynomial is X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+ X^4+X^2+X^1+X^0. Note that we take it "backwards" and put the highest-order term in the lowest-order bit. The X^32 term is "implied"; the LSB is the X^31 term, etc. The X^0 term (usually shown as "+1") results in the MSB being 1. The CRC utility will accept one mandatory parameter, either a file name or list of files and will then calculate the CRC for each inputted file. COMMAND /CRC File List
