Enter the password on the keyboard, one letter at a time. For each letter of the password you
enter, the RFL 9660 will echo back an asterisk (*).
NOTE
Passwords are case-sensitive.
If the super-user stored the password as all CAPITALS, you must
enter it that way. Otherwise, the RFL 9660 will reject it.
When you finish entering the password, press the
[ENTER]
key. If the RFL 9660 accepts the
password, your terminal will be connected to the device port. If it does not accept your
password, you will have to re-enter it.
Once your terminal is connected to the device port, the RFL 9660 is transparent to the
system and will only respond to the deselect code sequence ("BYE"). If this code interferes with
any of the application programs, notify the super-user. Only the super-user can change this
code. (See Section 5.)
4.8 DESELECTING A PORT
When you are finished using the device port, type in the deselect code, without pressing the
[ENTER]
key. (The
deselect code is usually "BYE," unless the super-user has stored another code in the RFL 9660's memory.)
Format: BYE
(no
[ENTER]
)
When the RFL 9660 receives the deselect code, it will disconnect you from the port (after a delay period that
can be changed by the super-user). Your normal prompt will appear again, and will be able to select another
port, or use any of the other general access commands. Also, other users will be able to use the device port you
were using.
If you forget to enter the deselect code and simply stop using your terminal, a timer inside the RFL 9660 starts
keeping track of the time. This timer is set at the factory for 10 minutes; it can only be reset by the super-user.
Once this timer times out, the RFL 9660 will disconnect your terminal from the device port. The RFL 9660 does
this to prevent one user from tying up a device and keeping other users from accessing it.
NOTE
The RFL 9660 will not respond if CTS/RTS or DTR/DSR flow control is involved and there is no device
connected to the selected port. You will have to wait for the timeout period to pass before the port will
be de-selected.
