- <H1>SCI Viewer - Terminal Emulator</H1>
- <P>The 68HC12 Simulator simulates one SCI port, SCI0. To maximize its usefulness, it is assume connected to a
- terminal emulator.</P>
- <P>The terminal emulator will display printable ASCII characters, and responds to the linefeed ($0a) character (by
- moving the cursor down), carriage return ($0d, moving the cursor to the left margin), bell ($07), and backspace
- ($08) character (backs up the cursor). It will also erase the screen with a $1a character, or by pressing the "clear"
- button. When the terminal has been selected for input, the cursor will appear in red.</P>
- <P>The keyboard input only supports ASCII characters, not the function keys, arrow keys, Insert/Delete, et cetera. </P>
- <P>The "Turbo" check box makes the serial port run at about 80 megabits per second, which is convenient for
- simulations since they will run faster. With turbo turned off, communications run at the configured rate. The "Binary
- Display" check box will cause the binary values of the characters to be displayed rather than the characters
- themselves. This can be useful for debugging strange output.</P>

- <P>When an input character code is displayed as in the figure above, it has yet to be transmitted. You probably won't
- see one displayed unless you are stepping through a program rather than just running it with "Go".</P>
- <P>It is important not to type input faster than it can be received. If the program being simulated echoes characters,
- wait until a character is echoed before typing an additional character. Otherwise, only type characters when no input
- character is indicated.</P>
