12. Packet Network Access
Valid values are: N (for None), 1, or 2, or 3.
Values 1 and 2 are generic supports for asynchronous data packet networks. If you choose one (l), the
LinkUp 5294 to generates cursor positioning as it usually does. If you choose two (2), the LinkUp 5294
relies on the network’s terminal node to perform cursor positioning by means of its local echo of escape
sequences, except in the following situations:
• When a screen wrap is required. This occurs when the cursor moves from the bottom to the top of
the screen, or from the right margin to the left margin.
• When fast cursor left and fast cursor right are invoked.
13. Auto Exit Enabled
Valid values are: YES or NO.
When YES is defined here, the LinkUp 5294 moves the cursor to the next System/3X input field after it
reaches the end of the field it is currently in, providing the field has been defined for auto-exit on your
3X host. To disable Auto Exit, specify NO for this parameter.
NOTE
When Parameter 12, Packet Network Access, is defined as N for none, then Parameter
13 cannot be defined as NO.

The Display Logical Unit Menu is shown below:
1. Associated Sync Port
Valid values are: 0 (for Port 0) or 1 (Port 1).
The value defined here lets the LinkUp 5294 know which physical synchronous port the LU under
configuration is assigned to. The 32 LUs available on the LinkUp 5294 may be assigned in whatever way
your application requires. For example, if you require only one synchronous port, then all the LUs can
be defined to that single port; if you require two synchronous ports to emulate two remote controllers,
you may divide the LUs between the two in any combination you wish.
