USES:
USES:
In summary, the printer port affords a very simple technique for interfacing with external circuitry. Twelve output bits are available, eight on the Data Port and four on the lower nibble of the Control Port. Inversions are necessary on three of the bits on the Control Port. Five inputs are available on the Status Port. One software inversion is necessary when reading these bits.

Serial Port
RS-232 was created for one purpose, to interface between Data Terminal Equipment (DTE) and Data Communications Equipment (DCE) employing serial binary data interchange. So as stated the DTE is the terminal or computer and the DCE is the modem or other communications device.

RS-232 Level Converters:
Almost all digital devices which we use require either CMOS (chemical metal oxide semiconductor) logic levels. Therefore the first step to connecting a device to the RS-232 port is to transform the RS-232 levels back into 0 and 5 Volts. As we have already covered, this is done by RS-232 Level Converters. Two common RS-232 Level Converters are the 1488 RS-232 Driver and the 1489 RS-232 Receiver. Each package contains 4 inverters of the one type, either Drivers or Receivers. The driver requires two supply rails, +7.5 to +15v and -7.5 to -15v. As you could imagine this may pose a problem in many instances where only a single supply of +5V is present. However the advantages of these IC's are they are cheap. Another device is the MAX-232. It includes a Charge Pump, which generates +10V and -10V from a single 5v supply. This I.C. also includes two receivers and two transmitters in the same package. This is handy in many cases when you only want to use the Transmit and Receive data Lines. You don't need to use two chips, one for the receive line and one for the transmit. However all this convenience comes at a price, but compared with the price of designing a new power supply it is very cheap. There are also many variations of these devices. The large values of capacitors are not only bulky, but also expensive. Therefore other devices are available which use smaller capacitors and even some with inbuilt capacitors. (Note: Some MAX-2321 can use 1 microfarad Capacitors). However the MAX-232 is the most common,

TRAINING AND TESTING OF NEURAL NETWORKS:
TRAINING AND TESTING OF NEURAL NETWORKS:
TRAINING
The process of training the neural system is like newly studying a subject. This a time consuming process. The system while training is given both the input and its corresponding output when used under the supervised learning mode.
TESTING
The neural system will also take only a short time to answer the questions posed to it. It is to note that only the questions are posed to us and not is answer and so we give only the input to the neural system while testing the neural system.
