Device names and interactive subsystem descriptions

For a long time, there were standards where I work as to naming
conventions for devices. But, since the system is on the way out in
maybe a year, other people are dictating things.

In the case of the above, the person who assists others establishing a
remote connection through the firewall has decided that it would be
easier if the device name was same as the user id.

We have two interactive subsystems. Each has a number of workstation
entries - composed of three characters followed by an asterisk.

I had forgotten about those entries when I created device descriptions
that start with C0 (a digit zero).

My day off today, and I received a call from work that the remote
users only got a blank screen. So, I added the C0* entry. I was told
later that it still did not work.

I am guessing that the subsystem needed to be restarted for the change
to take effect. Am I right, or is there something else that needs to
be done?
