Libbraille makes it easy to access Braille displays and terminals. It can write text on a Braille display, directly draw Braille dots, or get the value of pressed keys. It is compatible with a wide range of Braille displays, and can autodetect some of them. A virtual GTK+ display is provided so that developers can test how their application would be rendered in Braille.
(Serial Ports on) Steroids enables users to execute remote C functions in a Python shell over a serial interface. It is useful for embedded system testing and industrial automation. It generates C code for the target and a Python script for the host automatically from a C header file.
The Tinyserial library is a space-saving alternative to the Arduino software distribution's libraries for reading and writing characters and strings to the USART0 serial port on the Atmel ATmega168 and ATmega328p MCUs found on Arduino Diecimilla and Duemilanove boards. While the Arduino software distribution's libraries provide interrupt-driven serial I/O with far more features and support more MCUs, the Tinyserial library provides only the most basic polling-based serial I/O. However, the Tinyserial library uses far less Flash and SRAM, thereby giving you room to implement larger and more complicated applications on your boards. The Tinyserial library respects the GNU libc ABI, so you can call into it from C and C++ programs.
Qodem is a re-implementation of the Qmodem DOS shareware communications package, updated for more modern uses. Major features include Unicode support, scrollback buffer, capture file, screen dump, dialing directory, keyboard macros, script support, Xmodem, Ymodem, Zmodem, and Kermit. It can connect over serial port, telnet, ssh, rlogin, and command line, and supports multiple terminal emulations including ANSI.SYS, Avatar, VT100/102, VT220, and Linux.
