Introduction/Use
~~~~~~~~~~~~~~~~~~

One way transfer should work with any xpr aware commprog if option XN is used,
birectional transfer will need commprog to understand unofficial xpr2.001.
Remember that this protocol is aimed to use only with error correcting modems
(v42/mnp). Of course you can use dmodem without that kind of modem but I
strongly recommend not to. This not mean that error detecting isn't secure.
It's only that protocol isn't designed to handle multiple errors efficiently.

There is major speedup when using DreamTerm 1.x with DModem, this is achieved
using internal double buffering in xprdmodem. This technique offers possibility
handle RXD while TXD is still running, this is very important when doing
bidirectional transfer.
(This was the main reason why I was forced to upgrade xpr2.0.)
