SunVTS 3.0 Test Reference Manual

Synchronous Testing Software Requirements

If you have zs(7D) serial ports on your machine, the synchronous devices may not exist. Look in the /dev directory for zsh (where h=0 and/or 1). If they do not exist, you can create them. Verify that the following two lines are in the /etc/ file. If they are not there, add them.

type=ddi_pseudo;name=zsh zsh\M0
type=ddi_pseudo;name=clone;minor=zsh zsh

Caution - Caution -

The white spaces in the lines above must be a single tab character before and after the zsh variables; using spaces will not work.

When these lines have been added to the /etc/ file:

  1. Change directories to /kernel/drv, and run the add_drv zsh command.

If this command does not work:

  1. run the rem_drv zsh command and then run the add_drv zsh command again.
