The TS-UART drivers that come with the board (the tsuart0.o core drive and
tsuart-73.o loader driver) should be all you need to use these additional
serial ports. Assuming you are not interested in 9-bit serial, the mapping
is as follows:
COM Primary------> CTS/RTS
3 /dev/ttyT8S0 -> /dev/ttyT8S4
4 /dev/ttyT8S1 -> /dev/ttyT8S5
5 /dev/ttyT8S2 -> /dev/ttyT8S6
6 /dev/ttyT8S3 -> /dev/ttyT8S7
So for example if you open /dev/ttyT8S4 then the RTS/CTS lines on the "COM3"
header will be used as Tx/Rx for ttyT8S4.

The TS-UARTs (FPGA UARTs) were designed to be very small, therefore it is
only possible to use one of the built-in baud rates:
2400, 4800, 9600, 19200,38400,57600,115200
