TERMINAL SERVERS
Each command group affects either the Permanent Data Base (PDB)
or the Operational Data Base (ODB) setup of the Terminal Server.The PDB
resides in non-volatile memory so its contents are saved even without external
power connected to the Terminal Server. The ODB, however, resides in
regular RAM (Random Access Memory) which means that any changes made
to the ODB will be lost if the Terminal Server is disconnected from its power
source or is reinitialized in any other way.
When the Terminal Server is switched on, the contents of the PDB are
copies to the ODB. In fact, parameters associated with the serial and parallel
ports of the Terminal Server are copied from the PDB to the ODB each time
that port is accessed or disconnected.
Table 4-4
shows the confines of each management command: (A
√
indicates that the specified database is influenced by the relevant command
while an X means that it is not influenced).
