Establishing dial-out calls through terminal-server connections
Establishing dial-out calls through terminal-server
connections
The terminal server provides a way for users on the MAX unit’s local network connect to issue
AT commands to the modem as if they were connected locally to the modem’s asynchronous
port. The dial-out can occur in one of two ways:
•
Immediate modem dial-out, in which users Telnet directly to a port on the MAX for
immediate dial-out service, without accessing the terminal-server interface.
•
Nonimmediate modem dial-out, in which users on a workstation connect by Telnet to the
MAX terminal server for dial-out service.
To set up the MAX for digital modem dia-out, define the following:
•
Whether the modem dial-out function is enabled (the Modem Dialout parameter).
•
If you are using immediate mode, whether the immediate modem mode is enabled,
permitting users to Telnet to the MAX for dial-out service without accessing the
terminal-server interface (the Immediate Modem parameter).
•
If you are using immediate mode, the port number for immediate modem dial-out, which
specifies that all Telnet sessions initiated with this port number require modem access (the
Imm. Modem Port parameter).
•
If you are using immediate mode, an optional password of as many as 64 characters for
modem access (the Imm. Modem Pwd parameter).
Using immediate modem dial-out
To access a modem directly, the user performs the following procedure:
1
From a workstation, Telnet to a MAX unit, specifying the immediate-modem port number
on the command line. For example:
telnet max01 5000
Replace
max01
with the system name of the MAX unit and
5000
with the immediate
modem port number.
2
Use standard Rockwell AT commands to dial out on the modem. For example:
ATDT 1V1 ^M
3
Press Ctrl-C to terminate the connection.
Using nonimmediate modem dial-out
To access a modem through the terminal server, the user performs the following procedure:
1
From a workstation, Telnet to a MAX unit. For example:
telnet max01
2
When the Telnet session has been established, access the terminal-server CLI (System >
Sys Diag > Term Serv).
3
At the terminal-server prompt, enter the Open command:
ascend% open
