Internal Serial Port COM2 (V.24)
This port is connected in parallel to the external COM2 port. Both ports can
therefore only be used alternatively. The assignment is executed in such a way
that a 1:1 connection to a 9 pin subminiature Cannon socket can be made when
using insulation piercing connecting devices. The maximum cable length is 100cm
with a data transfer rate of 9.6 Kbps.
