This port is connected in parallel to the external COM2 port. Both ports can
therefore only be used as alternately. They are assigned such that a 1:1
connection can be established to a 9-pin D-SUB socket when insulation
displacement connectors are used. The maximum cable length is 100 cm at a data
rate of 9.6 kbaud.
