|
SOH Clears Screen |
Select this option to clear the page containing the cursor when T27 receives an SOH character from the host. This ensures that the host has an empty page on which to write data. If you clear this option, T27 takes no action when it receives an SOH character. This option applies to nonforms mode only. |
|
SOH Exits Forms |

|
ETX Advance |
Select this option to move the Datacomm pointer one position to the right of the ETX location when T27 receives an ETX character (end of text character) from the host. If you clear this option, T27 moves the Datacomm pointer to the ETX location. |
|
Forms Transmit To Cursor |
Select this option to transmit all transmittable fields between home and the cursor position when the session is in forms mode. If you clear this option, T27 transmits all transmittable fields on the page. |
|
Line At A Time Transmit |
Select this option to transmit only the line containing the cursor. If you clear this option, T27 transmits the entire page. NOTE:This option does not affect transmissions when you press the minus key (-) on the numeric keypad. |
|
Raw 8-Bit Data |
Select this option to transmit extended characters to the host and preserve the values above ASCII 127. If you clear this option, T27 transmits extended characters as 7-bit characters. |
|
Enable Mobile Home |
Select this option to allow host sequences to set a mobile home. If you clear this option, any host sequence that sets a mobile home will be ignored. |
