TN3270 Attention Key Sequence
This parameter determines the sequence of characters sent to the host whenever the TN3270 Attention key is pressed. Unfortunately, there is no industry standard method of sending the TN3270 Attention key using basic TN3270. As a result, PASSPORT supports the TN3270 Attention key differently depending upon the TN3270 Server. Select Telnet if you use a non-IBM TCP/IP host package. Select IBM if you use an IBM TN3270 Server or IBM mainframe TCP/IP host program. When TN3270E is configured, this configuration parameter is not available and ignored, as TN3270E offers a standard method to send the TN3270 Attention key to the host.

Backspace Key Method
This setting determines how the backspace key performs. The backspace key method can be set to any of the following:

Show Unprotected Fields
Enable and select one of the following to determine how unprotected fields are displayed on the screen: Dot, Underline (default) or Reverse Video.

Automatically Unlock Keyboard and Reset X SYSTEM
If you press the ENTER key or some other host key and the X SYSTEM stays on the OIA line and does not go away, then select this check box. This can occur when the IBM Host application does not send the Keyboard Unlock command to PASSPORT. This rarely happens, but when it does, it is usually with very old mainframe programs, and with CICS.

Numeric Field Checking
When enabled, this function allows only the numbers "0" through "9", the "+", the "-", the "." and the "," characters to be entered into TN3270 fields that are marked as numeric entry fields. "NUM" is displayed in the Operator Information Area (OIA) whenever the cursor is positioned on a numeric field.

Send Reset key before Tab and Arrow Keys
If you check this option and you use any of the up, down, left or right arrow keys, or the Tab, Back Tab, Home or Newline keys, the Reset key is sent first to release any keyboard inhibit condition. A keyboard inhibit condition is indicated by the X in the OIA status line. Then the up, down, left or right arrow key is sent to move the cursor accordingly.

Display 3270 Program Check Error
If you check this option, any invalid 3270 data stream program check error messages are displayed in the Operator Information Area (OIA) in the form of X PROG xxx. The user must issue a RESET command to clear the error and continue. Un-check this option to ignore the invalid data stream and prevent the program check errors from displaying. For a list of possible messages, please refer to Program Check Errors in the Technical Reference section.

Reset Insert Mode when AID Sent to Host
When enabled, insert mode is turned off whenever and AID key (Enter, PF1, etc.) is sent to the host. When disabled, insert mode is not affected when AID keys are sent to the host.

Allow Cursor Movement to Unprotected Fields Only
When enabled, the cursor can only be moved to unprotected fields. If an attempt to move the cursor to a protected field is made the cursor is not moved. When disabled, the cursor can be positioned anywhere on the host screen including both protected and unprotected fields.

Display Host Response Time on OIA Line
Enable this option to display in seconds the host response time after an AID key is pressed. This option is disabled by default.
