Do Not Enter The Do Not Enter ( ) symbol appears when input from the keyboard or mouse is not accepted by the host (except Reset and SysReq). Symbols to the right of this indicate the reason. Pressing the Reset key removes some of these symbols from the status line. Note that the emulation includes typeahead capability so that in most cases you can continue to enter data without waiting for the Do Not Enter message to clear as the data is stored until the host is ready. Indicates that a programming error in the data from the host has been detected, possibly due to incompatible application software. Press the Reset or SysReq key to remove this indicator and unlock the keyboard. Indicates that you must wait while the requested function is performed. Indicates that you tried to enter an invalid character into a numeric field when the numeric-lock feature was active. The keyboard numeric-lock feature can be overridden by using a Shift key. The keyboard can be unlocked and the indicator removed by pressing the Reset key. Indicates that you tried to enter data in the wrong location. This occurs when you attempt to do any of the following: • Enter, insert, erase, or delete a character when the cursor is in a protected field or at a field attribute location. • Perform a cursor-select operation when the cursor is not in a valid cursor-select field. • The keyboard can be unlocked and the indicator removed by press- ing the Reset key. Indicates that you cannot enter any data because the application program has disabled the keyboard following an entry. Indicates that you attempted to insert characters into an unprotected field when the cursor was at the end of the field, or you attempted to word wrap to the next line when there were not enough spaces to enable a word wrap. The keyboard can be unlocked and the indicator removed by pressing the Reset key. 6-6 IBM 3270 Emulation
