  Note: Depending upon your product type, this dialog may vary. This help context covers all possible configuration parameters. If your dialog does not contain certain parameters, they don't apply to the product you are configuring.
  Some features are only available for Terminal ports

NAU Name

  This optional field enables you to assign a name to the port. NAU names must be unique to the unit.
  Range: Up to eight alphanumeric characters

Initial State

  This option defines the port's state at system startup. If disabled, an operator must manually enable the port.
  Range: Disabled

Carrier

  This selects the type of carrier used by the port.
  Range: Switched (modem), or Constant

Clocking

  This option determines whether the port uses internal or external clocking.
  Range: Internal, External, X.21 Internal, or X.21 External

Target Host

  This parameter specifies which type of host your are connecting to. If the target host is SNA, the unit performs a bisync-to-SNA conversion to the attached CUs.
  Range: Bisync, SNA, or Tandem ICE

Speed

  This value determines the speed at which the port operates. If the port is externally clocked, the speed is determined by the clocking device, providing it doesn't exceed the maximum rate.
  Range: Dependent upon the attached devices

Signal Control

  Click on this button to define the conditions which determine the port's status.

Pause

  This value defines the amount of time that must elapse before a polling cycle repeats on the line.
  Range: 0 -- 25.5 seconds (in .05 increments)

Slow poll Timer

  This parameter defines the number of seconds the unit must wait between attempts to contact a PU that is off-line. This limits the wait time for off-line PUs to respond to polls.
  Range: 1 -- 99 seconds

Retry Count

  This value defines the number of times the unit attempts to complete a protocol exchange with a connected device before failing it. This prevents the unit from prematurely failing devices due to a temporary loss of response.
  Range: 1 -- 20 times

IBM 3270 Bisync

  This parameter enables the port to support non-IBM 3270 controllers.
  IBM 3270 BSC implementation requires an ESC character which some non-IBM 3270 BSC controllers cannot handle. If this port supports non-IBM controllers, disable this feature.
  Range: Enabled or Disabled
