[comp.sys.mac.programmer] Mac Xmodem ???

Does anyone know the Mac Binary Xmodem protocol or where I can get specs ?
It seems to tack on creator and type attributes and, I think, does both
forks.

I'm pretty sure that the MacBinary (and MacBinary II) protocol is seperate
from the XModem protocol.  Certainly, you could write code to handle both
at the same time, but neither is dependent on the other.  Xmodem is for
ensure data integrity, whereas the MacBinary protocol deals with the
transmittal of Finder and Mac System-specific information.

The worst thing about this followup is that I don't have any useful
information on either and so you still don't have what you were looking
for.  Sorry!  I wish I could help more...
