2.Issue a Connect command to the desired port. CONNECT <port>

3.To end a device session that was initiated with a Connect command, issue a Disconnect command.

DISCONNECT

For more information, see Server CLI command on page 51, Connect Command on page 43 and Disconnect Command on page 43.

Configuring and using dial-in connections

You may attach an external modem to the serial CLI port for dial-in serial CLI access to the CPS appliance. This may be used as a backup connection if the unit is not accessible from the network. It may also be used as a primary connection at remote sites that do not have Ethernet network capability. The modem must be Hayes compatible.

To specify a modem initialization string:

1.Issue a Show Server CLI command to ensure that the port where the modem is connected has been defined as the serial CLI port.

SHOW SERVER CLI

2.Issue a Server CLI command, using the Modeminit parameter to specify the modem initializa- tion string.

SERVER CLI MODEMINIT=“<string>”

The string must be enclosed in quotes and must include at least the command settings ATV1 and SO=1, which cause the modem to issue verbose response strings and auto-answer the phone on the first ring. For more information, see Server CLI command on page 51.

The modem initialization string is sent to the cabled modem when any of the following conditions occur:

•CPS appliance initialization

•Detection of a transition of DSR from low to high

•Completion of a call when DCD changes from high to low

3.Upon successful modem connection, press the Enter key until the login prompt appears.

To display modem configuration information:

Issue a Show Server CLI command.

SHOW SERVER CLI

For more information, see Show Server CLI command on page 65.

Connecting to devices using PPP

The CPS network appliance supports remote PPP access using an auto-answer modem that answers calls and establishes the PPP protocol with a dial-in client.
