Interactive Connections

Using the MSS

5.2.1.4 Disconnect and Resume

Users need a method of controlling and disconnecting sessions from local mode. For example, if a session on a remote host freezes or hangs while executing code, the user can exit the session using the Break key, then terminate the connection by entering the Disconnect command at the Local prompt. A user may resume a session after returning to local mode by entering the Resume command. Both commands can affect any active sessions, not just the current session.

5.2.1.5 Session Limits

The number of active session a user can have on the MSS is limited by three factors: available server memory resources, a server-wide limit, and a port- speciÞc limit. The absolute maximum number of sessions for the MSS is eight. To reduce the limit further, enter the Change Session Limit command followed by a number from one to seven.

5.2.2 Outgoing Connections

The MSS can make outgoing connections to hosts on TCP/IP, IPX/SPX, and LAT networks.

NOTE: Outgoing connections can only be made from the serial port.

5.2.2.1 Telnet

To start an outgoing Telnet session to a remote host on a TCP/IP network, type Telnet at the Local prompt, followed by either the hostÕs name or its numeric IP address.

Local> TELNET 192.0.1.66

NOTE: If a preferred or dedicated service has been configured, a host name is not required.

You can also make a Telnet connection to a speciÞc port number, as described in Emulating a Direct Serial Connection on page 5-11.
