The optional Exclusive parameter requests exclusive access to the port. This is valid only if the port is not currently in use. See Session sharing on page 23 for more information.

If you do not specify a port, a menu will be displayed, listing the ports that are available for serial connection. Enter a port number or name, or press Enter to cancel the command. If a valid port is specified, a message Connected to port ... appears. This message includes the port name plus the configured settings for baud, data bits, parity, stop bits and flow control.

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 65, Connect Command on page 53 and Disconnect Command on page 54.

Configuring and using dial-in connections

You may attach an external modem to the console port for dial-in serial CLI access to the CCM appliance. This may be used as a backup connection if the appliance 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 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 S0=1, which cause the modem to issue verbose response strings and autoanswer the phone on the first ring. For more information, see Server CLI command on page 65.

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

•CCM appliance initialization

•Detection of a transition of DSR from low to high

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

2.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 81.

Using PPP

The CCM appliance supports remote PPP access using an autoanswer modem that answers calls and establishes the PPP protocol with a dial-in client. You may establish Telnet or SSH connections over PPP.
