===============================
XMODEM file transfer protocol
===============================
.. $Id$
This is a literal implementation of XMODEM.TXT_, XMODEM1K.TXT_ and
XMODMCRC.TXT_, support for YMODEM and ZMODEM is pending. YMODEM should
be fairly easy to implement as it is a hack on top of the XMODEM
protocol using sequence bytes ``0x00`` for sending file names (and some
meta data).
.. _XMODEM.TXT: doc/XMODEM.TXT
.. _XMODEM1K.TXT: doc/XMODEM1K.TXT
.. _XMODMCRC.TXT: doc/XMODMCRC.TXT
Data flow example including error recovery
==========================================
Here is a sample of the data flow, sending a 3-block message.
It includes the two most common line hits - a garbaged block,
and an ``ACK`` reply getting garbaged. ``CRC`` or ``CSUM`` represents
the checksum bytes.
