Operation 12
Whenever a character appears in the last position of the top three rows, the cursor will move
to the leftmost position on the next row. Whenever a character appears in the last position on
the bottom row, the terminal will temporarily hide the cursor. After scrolling the screen up
one row, the TechTerm will display the next character in the first position on a new bottom
row followed by the cursor.
Operating Modes
TechTerms have several operating modes. The default mode is Terminal mode. It allows the
terminal to display characters, respond to commands sent by a connecting device, and send
characters to the connecting device as keys are pressed. Other modes, described later in this
manual, enable you to
set operating parameters and program function key definitions .
Host Control
The design of TechTerms allows a connecting device (or “ host ”) to control its functions
through the transmission of a string of special characters.
Referred to as “ Escape commands ” (because each character string begins with the ASCII escape
character), these character strings enable the host to move the cursor, sound an alert,
program the function keys and set any of the operating parameters.
