As do lots of devices used in the lab today. They are con-
nected via the serial port (you often can set if parity is
to be used) andthere are still lots of them and even quite
a number of new devices still can be controlled via serial
port, although they normally also have a GPIB or USB con-
nector or are networked. Can be quite useful for debugging:
for USB, GPIB or network you typically need to write pro-
grams to talk to them, while with the serial interface you
plug them in, start a program like 'minicom' and then you
can directly communicate with the device by typing in com-
mands and see what's the reply.
