New Features for DTS/TIO Subsystem
connection is allowed to each system. This is because each system must
configure the DTC port on a specific LDEV (nailed devices). if the
connections are to HP3000 systems using PC-based management, then
more than one connections is allowed. This is because it is allowed to
configure the DTC port to use non-nailed LDEVs. If the DTC port on
the PC-based system is configured as nailed, then only one connection
is allowed to that system.
This feature is configured on the terminal profile switching
configuration screen. The maximum number of connections is five and
the default is one.
Number Of Hosts Sharing Printer
Host-based printer switching allows the serial printer connected to a
DTC port to be shared by more than one HP 3000 host. You can now use
NMMGR to configure the DTC port to allow a printer to be shared by up
to 5 hosts. This feature is configured on the printer profile switching
configuration screen. The maximum number of systems that can share
at one time is 5 and default is 1. Thus the number of HP 3000 hosts
that can share a printer is increased.
Dynamic Configuration of New Port Fields
Dynamic Configuration provides the capability to perform DTS/TIO
configuration tasks without the need to shutdown the HP 3000 system.
With MPE/iX release 6.0, you can now change the following new fields
in a terminal, printer or host profile dynamically:
• Change "Data Length/Parity list" field in a terminal or printer
profile.
• Change "Number of Stop bits" field in a terminal or printer profile.
• Change "Enable Flow Control" field in a terminal or printer profile.
• Change "Enable Keep Alive" field in the profile for a switching port.
• Change "Maximum Number Of Sessions" field in the terminal profile
for a switching port.
• Change "Number of Hosts Sharing Printer" field in the printer
profile for a switching port.
• Change "Save Port Config in Binary" field in the terminal and
printer profile for a switching port.
You can now make dynamic configuration changes of these new fields
by using NMMGR to modify the configuration file
NMCONFIG.PUB.SYS, then invoking the command DTCCNTRL.
DTCCNTRL can be invoked by NMMGR after DTS validation has
successfully completed, or later by you from the CI prompt.
