The uTerm2-S (micro Term2 stand-alone) is an easy to build multi-emulation RS232 terminal using an ESP32-Wroom-32 module and the great FabGL library (http://www.fabglib.org). More, using an ESP32 gives the opportunity to use the uTerm2-S in a lot of different ways easily using the Arduino IDE with the ESP32 core.
These the main specs of uTerm2-S:
RS232 serial port;
"transparent" port for a serial-USB adapter (as in the uTerm-S);
secondary serial port for ESP32 programming using a serial-USB adapter;
RTS/CTS support between the RS232 and the "transparent" port (as in the uTerm-S);
on board power supply;
colors, graphics and sounds capabilities (FabGL library);
multi language keyboard support (FabGL library);
various terminal emulations (FabGL library);
PS/2 connectors for keyboard and mouse;
on board amplifier for an external speaker.
