Description
PICS software was used for automation of off-line sorting of letters in the
post offices. The aim was to store information about all coded letters in the
PICS computer. When the next letter was fed into the sorting machine a signal
was transmitted along the network to PICS. It located the ZIP code of the letter
and sent the result back to the sorting machine within a very short time. Following
the PICS result the sorter was then able to sort the letter. As one PICS served
up to 70 sorters, each sending a lot of signals to PICS, to reach the required
real-time demands up to 2100 inquiries and answers per second with only one
time-out for 50 000 letters allowed) 1 GB RAM was used which stores the whole
information. For network communication datagram sockets for real-time critical
data, stream sockets and AnsaWare were used. Besides the sorters, PICS exchanged
information with a lot of other computers and systems using 3 network Ethernet
interfaces and one modem line. PICS was delivered to many customers in the world.
