7. To disconnect, enter a reset request.
Managing Connections and Access
Enter these commands at the EXEC prompt to manage your connections and access to the terminal.
Ctrl ^ X
Escape sequence command you use to escape out of the current connection and return to the EXEC prompt, where you can make another connection or enter other EXEC commands. Allows multiple connections.
To enter this sequence, simultaneously press the Ctrl and Shift and 6 keys, let go, then type the X key. (This sequence can be redefined by your system administrator.)
lock
Locks access to the terminal by requesting a temporary password that must be re-entered to access the terminal.
login
Allows you to change your login name by prompting for a new user name and password.
name-connection
Displays prompts to rename a connection number. Connection names and numbers are displayed by the where command.
resume [connection]
<Return>
Resumes the previous connection unless the optional connection argument is entered to resume a specific connection number or name. Pressing the Return key also resumes the previous connection. Use the where command to display open connections.
where
Lists all open connections. List includes connection number, host address, and name.
Monitoring Connections
Enter these commands at the EXEC prompt to monitor your connections.

Use only when the exit or quit commands do not terminate a connection. The optional connection argument specifies a connection number.
{exit|quit}
Either command terminates the EXEC and closes any active terminal
session.

X.121-address--X.121 address.
hostname--Defined X.25 host name.
/cud text--Switch that includes text in the Call User Data field of the outgoing Call Request Packet.
/debug--Switch that causes the informational level of logging messages to be printed whenever the remote host changes an X.3 parameter setting or sends any other X.29 control packet.
/reverse--Switch that causes Reverse Charge calls to be accepted on a per-call, rather than a per-interface, basis.
Example:
CPT>pad 77630 /reverse
Setting X.3 PAD Parameters
Enter these commands to set X.3 PAD parameters. See Table 1 for parameter numbers and values.
resume [connection] [/keyword] [/set parameter:value]
Resumes PAD connections and allows changing local X.3 parameters during a connection.
connection--Connection number.
The argument /keyword is one of:
/line--Enables line-mode editing.
/noline--Disables line mode and enables character-at-a-time mode, which is the default.
/debug--Displays informational messages whenever the remote host changes an X.3 parameter or sends an X.29 control packet.
/nodebug--Disables the informational display, which is the default.
/echo--Enables local echo, which is the default.
/noecho--Disables local echo.
The /set switch sets the X.3 parameters defined by parameter number and value, separated by a colon. These parameters and their values are described in Table 1 at the end of this booklet.
For outgoing connections, the X.3 parameters default to the following:
2:1, 3:2, 4:1, 7:4, 16:127, 17:21, 18:19
All other parameters default to zero, but can be changed using the /set switch.
For incoming PAD connections, software sends an X.29 SET PARAMETER packet to set only the following parameters:
2:0, 4:1, 7:21, 15:0
Example:
Reset the outgoing connection default for local echo mode.
CPT>resume 3 /set 2:1
x3
Sets local PAD parameters directly, without using a command switch.
Example:
Reset the outgoing connection default for local echo mode.
CPT>x3 2:1
