Overview This document describes the use of ANSI escape codes to control a network-connected display board. It includes instructions for text coloring, screen control, and cursor positioning, as well as guidance on establishing a network connection to the display board or a Lantronix UTS Serial Adapter.

ANSI Escape Codes Screen Control:

Clear Screen: '\033[2J' clears the entire display.

Reset Cursor: '\033[H' moves the cursor to the home position (top-left corner). Cursor Positioning:

Position Cursor: '\033[{line};{column}H' moves the cursor to the specified line and column. Color Configuration:

COLOR_GREEN_BLACK: Green text on a black background. ANSI Code: chr(27) + '[31{'.

COLOR_RED_BLACK: Red text on a black background. ANSI Code: chr(27) + '[30{'.

COLOR_ORANGE_BLACK: Orange text on a black background. ANSI Code: chr(27) + '[29{'.

COLOR_BLACK_GREEN: Black text on a green background. ANSI Code: chr(27) + '[63{'.

COLOR_BLACK_RED: Black text on a red background. ANSI Code: chr(27) + '[62{'.

COLOR_BLACK_ORANGE: Black text on an orange background. ANSI Code: chr(27) + '[61{'.

Network Connection to Display Board TCP/IP Connection:

To control a display board over a network, establish a TCP socket connection. IP Address: Replace '10.200.200.98' with the actual IP address of your display board. Port: Use port 23 for standard Telnet connections to the display board. Connection to Lantronix UTS Serial Adapter:

For connecting to devices through a Lantronix UTS Serial Adapter, use Telnet. IP Address: The IP of the Lantronix adapter. Port: Use port 9999 for the Lantronix UTS Serial Adapter (Model: Snr 1363-058 V3.6).

import socket import time

COLUMNS = 32 LINES = 4

COLOR_GREEN_BLACK = chr(27) + '[31{' COLOR_RED_BLACK = chr(27) + '[30{' COLOR_ORANGE_BLACK = chr(27) + '[29{' COLOR_BLACK_GREEN = chr(27) + '[63{' COLOR_BLACK_RED = chr(27) + '[62{' COLOR_BLACK_ORANGE = chr(27) + '[61{'

1. Constants

DISPLAY_TEXT = "Hack RVA" DISPLAY_DELAY = 2 # Delay for display in seconds

1. Establish socket connection

host = '10.200.200.98' # Replace with the correct host port = 23 # Replace with the correct port sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect((host, port))

1. Clear the display

sock.sendall(chr(27).encode() + "[2J".encode())

1. Reset cursor

sock.sendall(chr(27).encode() + "[H".encode())

1. set cursor position

cursor_position = chr(27) + f'[{2};{10}H' sock.sendall(cursor_position.encode())

1. Display the text in

message = COLOR_BLACK_RED + DISPLAY_TEXT sock.sendall(message.encode())

1. Wait for a while

time.sleep(DISPLAY_DELAY)

1. Close the socket

sock.close()
