Keylock
The keyboard lock connection is lo-
cated on JK1. Utilizing this header
allows you to inhibit any actions
made on the keyboard, effectively
"locking" it.
Serial Ports
The COM1 (J3) and COM2 (J4) se-
rial ports are located under the
parallel port (see Figure 2-3). See
the table on the right for pin defini-
tions.
