COM1 and COM2 RS-232
~~~~~~~~~~~~~~~~~~~~
COM1 is connected to ser0 on ETRAX 100. /dev/ttyS0 in Linux/ETRAX.
COM2 is connected to ser2 on ETRAX 100. /dev/ttyS2 in Linux/ETRAX.
The DTR, RI, DSR and CD signals are connected to the general port
PA and PB bit 4-7.

RS422/RS485 screw terminal block connector
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Either an 8 pin 3.81 mm (X9) or an 12 pin 2.5 mm (X19) can be mounted.
The RS422/RS485 port is connected to ser3 on ETRAX 100. /dev/ttyS3 in
Linux/ETRAX.
The direction of the combined RX/TX pair on pin 5 and 6 on X9 (7 and 9 on X19)
is controlled by the RTS signal. When RTS is active (low), the driver is set
in receive mode.
The combined pair is used for half duplex RS-485.

pin 26 is the direction (output).
The LPT1 port is connected to par0 on ETRAX 100. /dev/lp0 in Linux/ETRAX.
The par0 port has a bidirectional buffer/driver on the data lines and
the outputs are connected through inverting drivers (not OUTPUT_ENABLE).

~~~~~~~~~~~
The TEST button is connected to general port pin PA1 (input),
when the button is pressed the value will be 0, otherwise 1.
STATUS LED
~~~~~~~~~~
The STATUS LED is connected to general port pin PA2 (output),
when the bit is set to 0, current will be sinked through the LED
and it will light.
