UART5 (connector X8) is selected as RS-232 at default setting.
JP79
Select, whether SIN5 is connected to RS-232- or LIN-transceiver
JP81
Select, whether SOT5 is connected to RS-232- or LIN-transceiver
JP84
Select, whether RS-232- or LIN-transceiver is connected to X8 pin2 (shared pin)
JP78
Some terminal programs needs a connection between CTS and RTS
JP80
Selects, whether DTR or RTS will be used for system
reset generation
JP85
Enables the LIN transceiver
JP86
Selects, whether UART5 will be LIN master or LIN
slave
