CHAPTER 7: Operation
67
An IBM 5251 Model 12 controller uses LSIDs numbered 0 and 2 through 9.
An IBM 5294 controller uses LSIDs numbered 0 through 9.
An IBM 5394 controller uses LSIDs numbered 0 through 0F.
4. Buffer Size
Valid value is: 1920.
There is only one value possible for this parameter. This is because 1920 is the standard buffer size of a
5250 Display.
5, 6. Number of Screen Rows/Number of Screen Columns
Valid value is: 24 (rows) by 80 (columns).
There is only one value possible for these parameters. This is because 24 by 80 is the standard size of a
5250 Display.
7. Password
Valid values are: Any combination of 1 to 6 alphanumeric characters, or NONE.
Specifying a password enables the LinkUp 5294 to protect the configured LU from being accessed
(during Connect Mode) by everyone but the terminal operator assigned to that LU (the one who knows
the password). When NONE is specified no password is defined, and the LinkUp 5294 cannot restrict
anyone from accessing the configured LU.
Whenever a password is defined at this parameter, the LinkUp 5294 can also offer you a second level of
password protection, called a Reconnect Password. A Reconnect Password allows the LinkUp 5294 to
restrict access to your LU (so that only you can re-access it, since you alone know the specified password)
in the event the LU session is interrupted due to a physical or logical disconnection; for example, if your
communication line drops or the LinkUp 5294 times out after reaching the specified Inactivity Time
Limit.
NOTE
Valid values for the Reconnect Password are: Any combination of 1 to 6 alphanumeric
characters or NONE. If NONE is specified, or if you simply skip over to the appropriate
Connect Mode prompt (by pressing <Enter>), the Reconnect Password defaults to the
first level password configured to the LU.
Once a password is defined, you cannot sign on to the LinkUp 5294 (during Connect
Mode, either initially or at a reconnect operation) until you successfully enter that
password. The LinkUp 5294 allows you three attempts before advising you that your
CONNECT REQUEST FAILED. When this message displays, the LinkUp 5294 also
reinitializes the affected asynchronous port. If you are remotely connected, your line
will be dropped.
8. Inactivity Time Limit
Valid values are: Any integer (representative of minutes) from 1 to 99, or NONE. When NONE is
specified, it means no inactivity time-out will occur.
