CHAP - The Challenge-Handshake Protocol is used to pass authentication
information between the client and server.  This information is encrypted
using either MD5 or DES techniques.  The Motorola implementation will
permit MLPPP CHAP sessions to MD5 servers (Ascend, Cisco, etc.) using
WIN95 clients.  This is accomplished by allowing the BitSURFR Pro to
authenticate the second channel.  Currently the Microsoft WIN95 client
does not support this second challenge.  Other clients on the market can
support the second challenge and do not require the @M20 command described
below for operation.

CHAP OPERATING PROCEDURE


To enable Challenge-Handshake Authentication Protocol , enter: 

	AT@M2=C for CHAP-MD5 
	
			or	

	AT@M2=M for CHAP-DES (Microsoft)

	and 
	
	AT@M20= "SECRET" where SECRET is the password you have entered in 
	your WIN95 dialer or internet communication package.   This is only
	for MD5 Multilink.  CHAP-DES Multilink is not supported for WIN95. 
	Other dialers may use "" to clear this field and operate in clear 
	CHAP mode.  Win95 cannot accept multiple challenges.

Notes: 
Please enter the double quotes shown above in addition to the password.

To clear out the password enter AT@M20="".

If you are not using Win95 with the BitSurfr Pro, the @M20 command is set 
to "".

The Dial String Modifier option allows you to enter a Password in each 
dial string. If this option is used in conjunction with the @M20 command,
the Dial String Modifier will supersede the password assigned in the 
@M20 command. 

To use the Dial String Modifier enter >P="secret" after the dial string.
(e.g. atd9,5551212>P="motorola").  The double quotes are required.
