	To begin with let's start with MNP - the MicroCom Networking Protocol -
which is now becoming an industry standard for data compression and error
correction in modems.  You should be able to take advantage of this function-0
ality with any other modem which also supports MNP-5, of which more and more are
appearing daily.  You can, of course, talk to any other 300/1200/2400 standard
modem w/o the MNP extras.
	Since MNP is hardware specific, in terms of configuring the modem to
use the 'auto-reliable mode' (MNP ON), MicroPhone II takes no special actions
in supporting MNP, as it does not need to!  As long as you have properly 
configured the modem (using those AT commands), then MPII (and any other
comm program) will talk to the modem and if the modem connects to another MNP
capable modem then the modems will take advantage of the MNP connection, and
the software won't/doesn't care!  You can, however, use protocols such as
YMODEM-G which will give you 96% (or more) effiecienty in speed due to it
assuming an error correctioin connection (ie. MNP On).
	If you do purchase MicroPhone II, our technical support staff will be
more than glad to help you through the setting up of the modem into 'auto-
reliable mode' as well as any other help you need.  Just a phone call (or
EMail messag) away.
