Is there anyone out there who can help me find a reasonable algorithm
for the CRC error checking scheme?  I have seen somewhere that the
"formula" is n^16 + n^12 + n^5 + 1 for the 2 CRC bytes found on floppy
disk formats.  I need a formula compatible with XMODEM protocol.  Is
it the same one?  If so what am I doing wrong...


thanx
