Reset an Alarm
When the CCU receives a reset alarm command, the CCU acknowledges
the alarm and stops the MultiCall assigned to the alarm. A reset
command from the host computer is assumed to mean the alarm point
has returned to its normal status. The CCU processes the alarms the
same as if they were input from an AIU-100 Alarm Interface Unit.

The communication protocol for the host computer input is 9600 baud, 8
data bits, 1 start bit, 1 stop bit, and 1 even parity bit. Each command
consists of a 3- or 4-byte packet. The checksum byte in each packet is the
exclusive OR (XOR) of the remaining bytes in the packet.
