Memory Mapped serial UARTs (TL16C2550) to physical port.

[morphinejh]

This feature adds Serial UART functionality to the emulator. It connects a real-world serial port on the host computer, USB or bus attached, to one of two possible emulator UARTs. It replicates the TL16C2550 - including FIFO, triggers, and interrupts.

It does not replicate Zimodem firmware, but allows it's addition through additional hardware (USB attached ESP32 or ESP8266).

It is MIT Licensed software and is placed in EXTERN folder.

Usage:

-uart1 [<COM port>]
        example: [/dev/ttyUSB0] (Posix) COM1 (Windows)
        Connect the system COM port devices to the the first UART
        This option is experimental.
-uart2 [<COM port>]
        example: /dev/ttyACM0 (Posix) COM2 (Windows)
        Connect the system COM port devices to the the second UART
        This option is experimental.
-uartaddr [<address>]
        If not specified, defaults to '$9FE0'
        UART2 is always UART1 address + 8.
        This option is experimental.

Secondarily it adds the release type to the make file build process.
-DCMAKE_BUILD_TYPE=Release
