Dave,
The very best, inexpensive resource for XMODEM, in *my* opinion, comes
in the book, "The Programmer's Guide to Serial Communications". This
book, by Tim Kientzle and published by Coriolis Group Books, covers the
XModem, YModem, ZModem and Kermit communications protocols and gives C
source. If you're writing for an 8051, you'll find C source incredibly
useful as many good 8051-C compilers and cross-compilers exist. It runs
$39.95 with disk-USDollars and has the ISBN 1-883577-20-9.
