I haven't fooled with XMODEM for years, but I know it is widely
used in many of the FIDONET BBS's.  You might get some information
from one of their sites.

I believe ZMODEM has all those features, plus being able to
restart from interruption point on reconnection as well.  It
has sort of become the current 'standard' among many of the
downloaders.
