Some of the programs are distributed only in source code form, because they need to be configured by editing strings in the source. The binary can then be assembled using the ASSEMBLE program.
Serial chat (Source) A simple program that reads data from stdin and sends it to a serial port, and reads data from the serial port and writes it to stdout. Can be used with redirected stdio.
Base64 encoder (Source) Reads data from stdin, encodes it to base64 and writes the base64 encoded data to stdout. (19. 6. 2023 fixed a bug in the stdout writing routine)
Base64 decoder (Source) Reads base64 encoded data from stdin, decodes it and writes the decoded data to stdout.
Telnet server (Source) Listens to a TCP port. When a socket is established, runs a payload program (for example the command prompt) and redirects its stdio to the socket.
HTTP server (Source) A simple HTTP server.
HTTP Request tools Tools to download files via HTTP protocol.
