ATLAS 800 Series System Manual Async-232 Option Module
Configuration
In Ctrl Write security: 3; Read security: 5
Selects the method by which incoming calls are indicated to and controlled by
the DTE. Options include the following:
Dialout Write security: 5; Read security: 5
Includes all options that affect dialing outgoing calls. The record field indicates
the values of the key dialout subfields.
Submenus Description
At Cmds
AT commands and responses indicate and control calls. AT commands also
support port and allocated modem or ISDN resource configuration.
DTR-DCD
An activated data carrier detect (DCD) signal indicates that an incoming call is
answered from the Async-232 Module port. Upon call hang-up, the DCD
becomes inactive. The data terminal ready (DTR) signal must be active from the
DTE for an incoming call to be answered. If the port is part of a group assigned
in the
DIAL PLAN, then the first idle port with DTR active will answer the call. If
the DTE drives DTR inactive, the Async-232 Module port hangs up an active
call.
AT/MDM
Indicates that AT dialing of a modem is selected.
DTR/MDM
Indicates that DTR dialing of a modem is selected.
AT/ISDN
Indicates that AT dialing of an ISDN resource is selected.
DTR/ISDN
Indicates that DTR dialing of an ISDN resource is selected.
Submenus Description
Dialout Method
Write security: 3, Read security: 5
Selects the method by which outgoing calls may be initiated by the DTE.
DTR Dial When DTR is enabled by the DTE and a number has been entered
in the
DTR DIAL NUMBER field, an outgoing call attempt is made.
The call is hung up when DTR is dropped. If the call does not
connect, the call will continue to be retried as long as DTR
remains active.
AT Dial When enabled, AT commands may be used to dial outgoing calls.
Port an allocated modem or ISDN resource configuration is also
supported via AT commands. The DTR signal must be active
from the DTE to dial out. The call is hung up when DTR is
dropped or when the escape-to-command mode sequence (+++)
and ATH are issued. When the call is connected, the Async-232
port enables DCD.
