or station PC, the station type is stored for a specific user or a specific computer.
User-specific relevance:
The Terminal Server Client checkbox is activated. The station type is defined for
the user. The user-specific parameters in the DNC database are updated.
Computer-specific relevance:
The Terminal Server Client checkbox is deactivated. The station type is defined
for the computer. The computer-specific parameters in the DNC database are
updated irrespective of the user logged on.
The following station types are available:

Only machines that are assigned to the terminal-specific station are displayed.
Data transfer is possible to the machines displayed.

All machines are displayed irrespective of whether they are assigned to the
terminal-specific station. Data transfer to the machines is not permitted.

Display all machines, data transfer only to assigned machines:
All machines are displayed irrespective of whether they are assigned to the
terminal-specific station. Data transfer is only permitted to machines that are
assigned to the terminal-specific station.

