Keywords: NT960 QNX2
Date: October 6, 1994
Under QNX 2.xx the NT960 utilizes an enhanced command line editor for terminals connected to the NT960 ACM ports.
Special features of NT960 firmware fqni0005.hex
The Nt960 firmware has a 20 line, 512 character per line, command line buffer, its special editing features are enabled when the +edit option is used. The command line is not passed to QNX2 until the enter (return) key is hit.
The backspace key works at the end of a line or within the command line. Depressing the key will delete characters to the left of the cursor and will move the preceding characters to the left. The command prompt can not be deleted, a warning bell will sound indicating the beginning of line.
Right and Left Arrows
Depressing these keys allow the user to navigate the cursor from left to right, within the command line. A beep is issued if you attempt left at the beginning of a line or right at the end of a line.
Up and Down Arrow Keys
The up and down keys allow the user to scroll thru the 20 line command line buffer. When the oldest command line is reached or the newest line in the line buffer is reached a beep is sounded.
Depressing the Insert key will place a “<<” character on the terminal screen indicating “insert mode”. The user can now insert characters into the command line. Depressing the key again, will remove the “<<” character and discontinue insert mode.
The home key will place the cursor at the beginning of a line.
The end key will place the cursor at the end of a line.
Will get the oldest command line from the line buffer.
Will get the most recent line entered in the line buffer. This will be blank line if no characters have been entered since the last return.
When within a command line the delete key will delete characters and move the preceding characters to the left.
