Asynchronous Protocols
Testing the Dial-In Connection
The access server and modem are now correctly configured for dial-in access. Before
configuring any additional protocols for the line (such as SLIP, PPP, or ARA), test the
dial-in connection.
Note Remember, the same configuration issues exist between the client DTE (PC) and
client modem. Make sure you have the correct EIA/TIA-232 cabling and modem
initialization string for your client modem.
The following is an example of a successful connection from a PC using a
U.S. Robotics Courier modem to dial into a Cisco 2500 series access server:
at&f&c1&d3&h1&r2&b1&m4&k1&w
OK

Asynchronous Protocols
The Cisco 2500 series access server supports a number of popular asynchronous protocols
for remote node connectivity. This section provides background information and
configuration guidance for accessing EXEC sessions and the asynchronous protocols PPP,
SLIP, and ARA.
It is important to be familiar with the concepts EXEC, autoselect, lines, and asynchronous
interfaces when you support asynchronous protocols.
