Asynchronous Network Interface
Configuration
This section shows how to configure the asynchronous Network Interface (NIF) by:
•
Setting up addressing.
•
Using the options in the PIPE.INI file.
The asynchronous network interface (NIFASY) allows two Piccolo systems to
communicate with each other over an asynchronous connection. The connection type
can be switched or dedicated using a null modem, dumb modem, or smart modem.
Each network interface controls a single communications device and any number of
network interfaces may be configured. A flexible script language allows you to control
smart modems during call answer and origination.
The asynchronous network interface resolves remote system addressing exclusively
from the Resolver section in the PIPE.INI configuration file. When a connection request
is received for a remote system, the Resolver section is searched for an entry that
matches the destination system name. The resulting address is examined for
asynchronous extended addressing tags, which are used to make the connection.
See Creating the [RESOLVER] Section (optional, for workstations only) on page 5-15,
for more information about the Resolver section.
Prerequisites to Configuring
To configure an asynchronous network interface, you should be familiar with the
asynchronous software that is installed on your system.
NIFASY NIF naming conventions follow the standard Piccolo NIF naming convention
and may be represented by any symbolic name in the PIPE.INI NifList option.
Whatever name is chosen, there must be a unique section specifying the NIF
configuration information.
Note. If you are using the NonStop, you must configure your asynchronous device using the
CMI or SCF. If you are using dialup or switched, you must enable CTSFLOW, TYPE (6,0), and
MODEM ON. If you are using leased or direct connect, you must enable TYPE (6,0) and
MODEM ON. CTSFLOW should also be configured to match the flow control of the
corresponding asynchronous device. See HP’s Communications Management Interface (CMI)
Operator Reference Manual or SCF Reference Manual for Asynchronous Terminals and
Printer Processes.
The asynchronous network interface is not compatible with large-message support. If you
attempt to start NIFASY while large messages are enabled, a critical error will be logged and
the NIFASY will not start.
