following characteristics:
Display: The minimum display size is 16 lines by 80 columns. The port provides both
carriage return and line feed characters to position the cursor at the start of the next line.
Destructive scrolling is also expected (new lines added at the bottom of the screen and top-
most lines disappear). Full duplex operation is required.
Alphabetic ASCII characters in
both upper-case and lower-case will be sent to the SAT, along with ASCII numerals and
some basic ASCII symbols. The device used must be capable of displaying ASCII alphabetic
characters when either upper-case or lower-case characters are received. However, upper-
to-lower case mapping (or vice-versa) for display is acceptable since no meaning is associated
with case.
Keyboard: The administration port requires ASCII alphanumeric characters as well as
some symbol characters.
If the keyboard generates only upper-case or only lower-case
alphabetic characters the administration port will respond appropriately, since upper and
lower case input is considered identical. The SAT should be capable of sending the following
