    FAQ [EMB-H81A]

    What's the max speed of each com port ?
    Com1 & Com2 →super I/O NCT6791D UART description: The NCT6791D-A provides two high-speed serial communication port (UART), which includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem-control capability, and a processor interrupt system. The UART supports legacy speeds up to 115.2k bps as well as even higher baud rates of 230K, 460K, or 921K bps to support higher speed modems. Com3~com6→super I/O NCT5104D: The NCT5104D is a LPC to UART IC, which supports 4 high-speed serial communication port (UART). Each UART includes a 128-byte send/receive FIFO, a programmable baud rate generator, complete modem-control capability, and a processor interrupt system. The UART supports legacy speeds up to 115.2K bps as well as even higher baud rates of 230K, 460K, or 921K bps to support higher speed modems.
