New Features for DTS/TIO Subsystem
With MPE/iX release 6.0, you can now use NMMGR to configure a
parameter in the Host-based TIO profiles to enable or disable flow
control. If this feature is enabled in NMMGR for terminal/ printer, the
data flow between the DTC port and the connection device is made with
Xon/Xoff characters. If this feature is disabled, the XON/XOFF
characters sent from device are not interpreted by DTC. This function is
also known as "software handshake." This new feature can be
supported on all DTCs except for DTC 16RX. Any value entered for this
type will be ignored.
Enable Keep Alive
This new feature allows you to specify whether "keep alive" mechanism
is to be activated. When there is no data transfer between the DTC and
the system, then a mechanism called "keep alive" is activated to detect
if the connection is still there. This new feature is only applicable to the
telnet/TCP connections. It is only available for switching screens for
terminal, printer and host profiles.
If this configuration is enabled, the "keep alive" mechanism is to be
activated to detect if a connection is still there when there is no data
transfer between the DTC and the system. This new feature can be
supported on all DTCs except DTC48 without the memory extension.
Save Port Config Binary
This new feature allows you to specify whether the port configuration
parameters- data length and parity get forced when binary mode is
selected. If set to YES, then the port configuration remains the same
when binary mode is selected. If set to NO, then data length is 8 bits
and parity is forced to none when binary mode is selected. This new
feature is only applicable to telnet/TCP connections. This parameter is
accessed from the terminal and printer profile switching configuration
screen and the host profile screen.
This new feature can apply only to the new DTCs — DTC 72MX, DTC
16MX and DTC 16iX.
Specify the Maximum Number of Sessions for a Switching
Port
Host-based terminal switching allows you to connect to other systems
on the LAN from a terminal connected to a DTC that is using
host-based management. In previous releases, each port on the DTC
was restricted to one connection per port. Connections from PAD ports
are still restricted to the system that is managing the DTC. To connect
to these systems, you needed to log off or close the connection before
connecting to an other system.
With MPE/iX release 6.0, you can now use NMMGR to configure each
DTC port to allow up to 5 connections at the same timer. If connections
are to HP3000 systems using Host-based management, then only one
