Devices are described as follows:
Speaker
an 8 ohm speaker can be directly connected to pins 7 and 8. All
necessary drivers are installed.
Reset
a Normally Open Push button can be connected to reset the TEK733
(electrical short between pin 13 and 14).
Hard Disk LED
the onboard IDE interface drives an external LED during the drive
activity. Anode must be connected to pin 16. No external current
limiting resistor is required since one is already present.
6.6 Serial Port #2 Connector

The TEK-AT4L
PLUS
features two UARTs which are functionally equivalent to the
NS16450. Both are configured as DTE.
