Guidelines for Running VHS

If you use the VHSSTART file to start VHS, you do not need to be concerned with the

following run-time guidelines. However, if you run VHS from TACL, make sure you

follow these guidelines:

•

VHS must be run as a named process because it is opened by other processes

and has device subtype 30 (device emulation).

•

VHS should be run as a process pair because it must be always available to

receive messages.

•

To run VHS with High PIN support, ensure that the #HIGHPIN built-in variable is

set to On at the TACL prompt.

Caution. The hometerm of VHS can be a dynamic device, such as a Telnet window, but this

might cause problems when the window is terminated. It is safer to start VHS with a physical

(static) device.
