Establishing Access Security on a Port
Although the password feature is available, it is not required as a factory default.
If used, it ensures access security before device control is passed to a device
connected to a port. The password configuration option can be individually set for
the COM or MODEM port, or both if security is needed on both port types. The
default is None. The password itself is set separately (refer to the following
section,

Setting a Password

).
Procedure
To establish access security on a port:
1. From the top-level menu screen, select Cnfig.
2. Select the configuration option set to be copied into the Edit area by using the
appropriate Function key. Use the scroll keys, if necessary.
3. Select Edit.
