Configuring an Interactive Device for LAT Sessions

Specifying AUTOPROMPT
The AUTOPROMPT characteristic is only used with the LAT protocol. This
characteristic controls the initiation of a login process on some service nodes when a
session begins. The access server sends the status of the AUTOPROMPT
characteristic whenever you establish a new LAT service session.
By default, AUTOPROMPT is enabled. If the service node supports AUTOPROMPT,
the service node performs a system-specific login sequence, such as displaying a
service announcement or login prompt.
If you disable AUTOPROMPT and the service node recognizes this, the service node
does not perform any login sequence. Since devices without keyboards cannot respond
to a login sequence, you should disable AUTOCONNECT for these devices.
Example: Disabling AUTOPROMPT
The following example shows how to disable AUTOPROMPT:
Local> CHANGE PORT 5 AUTOPROMPT DISABLED
Specifying the Default Protocol
The following options are available with the SET/DEFINE/CHANGE PORT
DEFAULT PROTOCOL command:
• LAT — The access server defaults to the LAT protocol when the user does not
specify a protocol in the CONNECT command.
• SLIP — The access server defaults to the SLIP protocol when the user does not
specify a protocol in the CONNECT command.
• TELNET — The access server defaults to the Telnet protocol when the user does
not specify a protocol in the CONNECT command.
• ANY — The access server first searches the network resources on the LAT
network when the user does not specify a protocol in the CONNECT command.
If unsuccessful, the access server then searches the network resources on the TCP/
IP network. The AUTOCONNECT characteristic must be disabled when the
default protocol is set to ANY.
• PPP — The access server defaults to the PPP protocol if the user does not specify
a protocol with the CONNECT command.
• AUTOLINK — The access server passively examines characters received from
the attached device. If the access server detects a PPP or SLIP connection, it
attempts to change the current session into the appropriate data link session type,
PPP or SLIP. If the access server cannot identify the data as PPP or SLIP, it starts
and interactive session.
An adjunct to the AUTOLINK protocol is AUTOLINK authentication. See
