Multiserver 5000
114
Note: The wild card (*) can be used to access a
range of ports. To access any async port in the
Multiserver identified by the name
NEW_YORK, you would type the following:
NEW_YORK/*
2. The CLASS PASSWORD prompt will appear
on the screen. If the destination port has been
configured as part of a class, enter the class
password.
3. If the port is not available, the screen will
display one of the following configurable
dialog messages:
Busy. The port is already connected to
another user. Try again.
No Answer. There is no answer from the
destination port. Causes include:
• Remote port did not respond to
connection protocol.
• There was no response within the call
time out period, although the port is
known by the local Multiserver.
Unavailable. The resource exists, but is not
in service (not operational), or receive inhibit
is enabled.
Unassigned. The node, class, or port is
unknown in the network. It could also mean
that you have entered a class password
incorrectly.
4. A connection message will appear on the
screen when the connection is complete across
the link.
Note: Matrix switching can be disabled on a
per-channel basis.
To disconnect from a matrix connection, press the
<break> key three times within six seconds. When
the connection is broken, the disconnect message
will be displayed on the screen of the calling port.
10.6 Matching Capability for Asynchronous
Channels
Feature matching automatically selects and sets the
minimum feature set for connecting async ports
during switching operations. The Multiserver does
not match features in force-connected async
channels.
Three features are automatically converted for
asynchronous channels:
• Speed. Called and calling ports do not need to
have the same speeds unless unbalanced rates
are set to OFF. The Multiserver will flow-control
the faster port to prevent overrunning the
slower port.
• Flow Control/Buffer Control. Ports with
different flow-control and buffer-control
mechanisms will be converted through the
Multiserver.
Note: Ports using no flow control connecting
with those using character (DC1/DC3,
DC2/DC4, and so forth) flow control may have
problems if they use the complete ASCII code
set, since the flow-control characters will not be
stripped out of the data stream.
• Parity. Even, odd, mark, and space will be
converted automatically at the receiving
Multiserver to match the required parity. See
Section 9.3, Asynchronous Channels, for
configuration specifics. Parity conversion works
on force-connected channels.
