A full list of available clients

HDSware Installation of HDSperx
The HDSware installation feature of the ViewStation is a simple
way to utilize the HDSperx clients and menus. When you use HDSware to
get started (specifying the HDSware host and path), the ViewStation
automatically locates the ./hds-fx/ config/clients.config file
and the HDSperx clients themselves in the HDSware directory, ./hds-fx/bin,
and automatically adds them to the window manager's menu file so they
are easily accessible from a submenu on your local window manager's
root menu. You must restart the ViewStation after you make the HDSware
entries so the configuration file will be read; you probably also want
to save these values in NVM.
Pre-loading Motif Libraries
The HDSperx clients, as well as HDSterm, use the Motif
libraries Xm and Xt in their operation. These libraries can be
preloaded when the ViewStation starts up so they are ready when you
select the clients. This can speed up the loading of the first client
you select. The default for the preload option is No.
hds.library.motif.preload: yes
There are
further resources in the ./hds-fx/config/clients.syntax.config
file to control this library loading feature: hds.client.<name>.shareCode:
[ no | yes ]
hds.client.<name>.shareFree: [ no | yes ]
hds.library.<name>.shareFree:
[ no | yes ]
These resources indicate whether the client named
should share its code with other instances of the same client, or
whether a separate copy of the code should be loaded. They can also
specify whether the code should be freed when the last instance of the
client exits. The same free characteristic applies to the libraries
loaded for the clients.
