The BitSURFR Pro supports most authentication methods in conjunction with single-link
PPP by "passing through" all authentication messages.

The BitSURFR Pro supports the following three authentication methods in conjunction
with the multi-link PPP: Password Authentication Protocol (PAP), Challenge-Handshake
Authentication Protocol (CHAP) and Shiva Password Authentication Protocol (SPAP).

CHAP supports multiple authentication algorithms, and the BitSURFR Pro supports two
of these algorithms: CHAP-MD5 and CHAP-MS.

The CHAP feature supports two message modes: Pass-through and Respond.  In 
Pass-through mode the BitSURFR Pro passes all challenge messages to the DTE.  In
Respond mode the BitSURFR Pro responds to all challenge messages by using the
provided password and the built-in algorithm.  You must use Respond mode for
proper operation of Windows 95 Dial-up Networking when used with MD5-CHAP.

Your BitSURFR Pro defaults to the Pass-through mode.  Respond mode is invoked either
by entering the AT command AT@M20="password" or the dial-string modifier 
>P="password".  The password in the dial-string modifier takes precedence over the 
password stored by the AT@M20 command.

SPAP offers encryption of PAP passwords and is commonly used by Shiva Remote Access
Servers.

The AT command "AT@M2" is no longer needed to enable PAP or CHAP.

-------------------------------------------------
New AT Command:

The command "AT@B2=n", where "n" is a value 0-255, may be used to limit the number
of times the BitSURFR Pro will attempt to connect the second channel of a Multi-link
PPP call, if the first attempt fails.  The default limit is 5.  If you set the limit
to 0, then the BitSURFR Pro will continuously try to connect the second channel until
the first channel is dropped.
